| Organization, Consolidation and Presentation of Financial Statements [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Nature of Business and Summary of Significant Accounting Policies | Nature of Business and Summary of Significant Accounting Policies Nature of business: Daktronics, Inc. and its subsidiaries are engaged principally in the design, manufacture and sale of a wide range of electronic display systems and related products which are sold in a variety of markets throughout the world and the rendering of related maintenance and professional services. Our products are designed primarily to inform and entertain people through the communication of content. Fiscal year: We operate on a 52 to 53 week fiscal year, with our fiscal year ending on the Saturday closest to April 30 of each year. When April 30 falls on a Wednesday, the fiscal year ends on the preceding Saturday. The fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011 each consisted of 52 weeks. Within each fiscal year, each quarter is comprised of 13 week periods following the beginning of each fiscal year. In each 53 week year, each of the last three quarters is comprised of a 13 week period, and an additional week is added to the first quarter of that fiscal year. Principles of consolidation: The consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries – Daktronics France SARL; Daktronics Shanghai, Ltd.; Daktronics GmbH; Daktronics UK, Ltd.; Daktronics HK Limited; Daktronics International Limited; Daktronics Canada, Inc.; Daktronics Beijing, Ltd.; Daktronics Australia Pty Ltd.; Daktronics Installation; Daktronics Japan, Inc.; Daktronics Brazil, Ltda.; Daktronics Singapore Pte. Ltd., and Daktronics Spain S.L. Intercompany balances and transactions have been eliminated in consolidation. Investments in affiliates over which we have significant influence are accounted for by the equity method. As of April 27, 2013 and April 28, 2012, we did not have any investments accounted for by the equity method. Prior to April 30, 2011, as explained in Note 16, we had various investments accounted for under the equity method. Investments in affiliates as to which we do not have the ability to exert significant influence over their operating and financing activities are accounted for under the cost method of accounting. We have evaluated our relationships with affiliates and have determined that these entities are either not variable interest entities or, in the case of variable interest entities, we are not the primary beneficiary and therefore they are not required to be consolidated in our consolidated financial statements. The equity method requires us to report our share of losses up to our equity investment amount, including any financial support made or committed to. At such time the equity investment is reduced to zero, we recognize losses to the extent of and as an adjustment to the other investments in the affiliate in order of seniority or priority in liquidation. Our proportional share of the respective affiliates' earnings or losses is included in other (expense) income in our consolidated statements of operations. As of May 1, 2010, we had a variable interest in Outcast Media International, Inc. (“Outcast”). During fiscal 2011, it became a cost method investee and ceased being treated as a variable interest entity. This occurred as a result of a reorganization of Outcast in connection with a sale of most of its assets. The results of the variable interest analysis we completed prior to fiscal 2011 indicated that we were not the primary beneficiary of this variable interest entity and, as a result, we were not required to consolidate it. Our analysis included reviewing the amount of financial support, equity risk, and board influence. As of April 27, 2013, our interest in Outcast consisted of a seven percent equity interest. During fiscal 2010, we had written down our equity investment to zero. During fiscal 2011, as described in Note 16, we exchanged certain debt and other obligations related to Outcast for a note from a third party related to Outcast. The aggregate amount of investments accounted for under the cost method was $106 at April 27, 2013 and April 28, 2012. The fair value of these investments has not been estimated, as there have not been any identified events or changes in circumstances that may have a significant adverse effect on their fair value, and it is not practical to estimate their fair value. Use of estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the estimated total costs on construction-type contracts, estimated costs to be incurred for product warranties, excess and obsolete inventory, the reserve for doubtful accounts, share-based compensation, goodwill impairment and income taxes. Changes in estimates are reflected in the periods in which they become known. Cash and cash equivalents: All highly liquid investments with maturities of three months or less at the date of purchase are considered to be cash equivalents and consist primarily of government repurchase agreements, savings accounts and money market accounts that are carried at cost, which approximates fair value. We maintain our cash in bank deposit accounts, the balances of which at times may exceed federally insured limits. We have not experienced any losses in such accounts. Restricted cash: Restricted cash consists of deposits to secure bank guarantees issued by our foreign subsidiaries. Inventories: Inventories are stated at the lower of cost (first-in, first-out method) or market. Market is determined on the basis of estimated net realizable values. Revenue recognition: Net sales are reported net of estimated sales returns and exclude sales taxes. We estimate our sales returns reserve based on historical return rates and analysis of specific accounts. Our sales returns reserve was $73 and $63 at April 27, 2013 and April 28, 2012, respectively. Long-term construction-type contracts: Earnings on construction-type contracts are recognized on the percentage-of-completion method, measured by the percentage of costs incurred to date to estimated total costs for each contract. Contract costs include all direct material and labor costs and those indirect costs related to contract performance. Indirect costs include charges for such items as facilities, engineering, and project management. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are probable and capable of being estimated. We combine contracts for accounting purposes when they are negotiated as a package with an overall profit margin objective, essentially represent an agreement to do a single project for a customer, involve interrelated construction activities, and are performed concurrently or sequentially. When a group of contracts is combined, revenue and profit are recognized uniformly over the performance of the combined projects. We segment revenues in accordance with contract segmenting criteria in Accounting Standards Codification (“ASC”) 650-35, Construction-Type and Production-Type Contracts. Equipment other than construction-type contracts: We recognize revenue on equipment sales, other than construction-type contracts, when title passes, which is usually upon shipment and then only if the terms of the arrangement are fixed and determinable and collectability is reasonably assured. We record estimated sales returns and discounts as a reduction of net sales in the same period revenue is recognized. Product maintenance: In connection with the sale of our products, we also occasionally sell separately priced extended warranties and product maintenance contracts. The revenue related to such contracts is deferred and recognized ratably as net sales over the terms of the contracts, which vary up to 10 years. We record unrealized revenue in deferred revenue (billed or collected) in the liability section of the balance sheet. Deferred revenue (billed or collected) excludes unrealized revenue from contractual obligations to be billed by us in future periods. Services: Revenues generated by us for services, such as event support, control room design, on-site training, equipment service and technical support of our equipment, are recognized as net sales when the services are performed. Net sales from services and product maintenance approximated 9.0 percent, 9.0 percent and 9.4 percent of net sales for the fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011, respectively. Multiple-element arrangements: We generate revenue from the sale of equipment and related services, including customization, installation and maintenance services. In these limited cases, we provide some or all of such equipment and services to our customers under the terms of a single multiple-element sales arrangement. These arrangements typically involve the sale of equipment bundled with some or all of these services, but they may also involve instances in which we have contracted to deliver multiple pieces of equipment over time rather than at a single point in time. When a sales arrangement involves multiple elements, the items included in the arrangement (deliverables) are evaluated pursuant to ASC 605-25, Revenue Arrangements with Multiple Deliverables and ASC 605-35, to determine whether they represent separate units of accounting. We perform this evaluation at the inception of an arrangement and as we deliver each item in the arrangement. We first consider the separation criteria of ASC 605-35. Deliverables not within the scope of ASC 605-35 are evaluated for separation under ASC 605-25. For those elements falling under the guidance of ASC 605-25, we generally account for a deliverable (or a group of deliverables) separately if the delivered item(s) has standalone value to the customer and if we have given the customer a general right of return relative to the delivered item(s) and delivery or performance of the undelivered item(s) or service(s) is probable and substantially in our control. When items included in a multiple-element arrangement represent separate units of accounting, we allocate the arrangement consideration to the individual items based on their relative fair values. The amount of arrangement consideration allocated to the delivered item(s) is limited to the amount not contingent on us delivering additional products or services. Once we have determined the amount, if any, of arrangement consideration allocable to the delivered item(s), we apply the applicable revenue recognition policy to determine when and by which method such amount may be recognized as revenue. We generally determine if objective and reliable evidence of fair value for the items included in a multiple-element arrangement exists based on whether we have vendor-specific objective evidence ("VSOE") of the price for which we sell an item on a standalone basis. If we do not have VSOE for the item, we will use the price charged by a competitor selling a comparable product or service on a standalone basis to similarly situated customers, if available. If neither VSOE nor third party evidence is available, we use our best estimate of the selling price for that deliverable. Software: We typically sell our proprietary software bundled with our video displays and certain other products, but we also sell our software separately. Pursuant to ASC 985-605, Software Revenue Recognition, revenues from software license fees on sales, other than construction-type contracts, are recognized when persuasive evidence of an agreement exists, delivery of the product has occurred, the fee is fixed and determinable, and collection is probable. For sales of software included in construction-type contracts, the revenue is recognized under the percentage-of-completion method starting when all of these criteria have been met. Long-term receivables and advertising rights: We occasionally sell and install our products at facilities in exchange for the rights to sell or to retain future advertising revenues. For these transactions, we recognize revenue for the amount of the present value of the future advertising payments if enough advertising is sold to obtain normal margins on the contract and we record the related receivable in long-term receivables. We recognize imputed interest as earned. On those transactions where we have not sold the advertising for the full value of the equipment at normal margins, we record the related cost of equipment as advertising rights. Revenue to the extent of the present value of the advertising payments is recognized in long-term receivables when it becomes fixed and determinable under the provisions of the applicable advertising contracts. At the time the revenue is recognized, costs of the equipment are recognized based on an estimate of overall margin expected. Any remaining costs are recorded in the costs of advertising rights. The cost of advertising rights, net of amortization, was $53 and $446 as of April 27, 2013 and April 28, 2012, respectively. Property and equipment: Property and equipment is stated at cost and depreciated principally on the straight-line method over the following estimated useful lives:
Leasehold improvements are depreciated over the lesser of the useful life of the asset or the term of the lease. Our depreciation expense was $15,379, $17,273 and $19,354 for the fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011, respectively. Long-Lived Assets: Long-lived assets other than goodwill and indefinite-lived intangible assets, as described in Note 4, which are separately tested for impairment, are evaluated for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. When evaluating long-lived assets for potential impairment, we first compare the carrying value of the asset to the asset's estimated future cash flows (undiscounted and without interest charges). If the estimated future cash flows are less than the carrying value of the asset, we calculate an impairment loss. The impairment loss calculation compares the carrying value of the asset to the asset's estimated fair value. We recognize an impairment loss if the amount of the asset's carrying value exceeds the asset's estimated fair value. If we recognize an impairment loss, the adjusted carrying amount of the asset becomes its new cost basis. For a depreciable long-lived asset, the new cost basis will be depreciated (amortized) over the remaining useful life of that asset. Our impairment loss calculations contain uncertainties because they require management to make assumptions and to apply judgment to estimate future cash flows and asset fair values, including forecasting useful lives of the assets and selecting the discount rate that reflects the risk inherent in future cash flows. Software costs: We capitalize certain costs incurred in connection with developing or obtaining internal-use software. Capitalized software costs are included in property and equipment on our consolidated balance sheets. Software costs that do not meet capitalization criteria are expensed immediately. Insurance: We are self-insured for certain losses related to health and liability claims and workers’ compensation, although we obtain third-party insurance to limit our exposure to these claims. We estimate our self-insured liabilities using a number of factors, including historical claims experience. Our self-insurance liability was $1,843 and $2,075 at April 27, 2013 and April 28, 2012, respectively, and is included in accrued expenses in our consolidated balance sheets. Foreign currency translation: Our foreign subsidiaries use the local currency of their respective countries as their functional currency. The assets and liabilities of foreign operations are generally translated at the exchange rates in effect at the balance sheet date. The operating results of foreign operations are translated at weighted average exchange rates. The related translation gains or losses are reported as a separate component of shareholders’ equity in accumulated other comprehensive (loss) income. Income taxes: We account for income taxes under ASC 740, Income Taxes, which requires recognition of deferred tax liabilities and assets for the expected future tax consequences of events included in our financial statements or tax returns. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. ASC 740 requires the consideration of a valuation allowance for deferred tax assets if it is “more likely than not” some component or all of the benefits of deferred tax assets will not be realized. Tax rate changes are reflected in income during the period such changes are enacted. We have benefited from a tax holiday in China that expired in fiscal 2012. In fiscal 2012 and 2011, we realized a benefit of approximately $249 or $0.006 per share and $77 or $0.002 per share, respectively. Our income tax returns, like those of most companies, are periodically audited by U.S. federal, state and local and foreign tax authorities. These audits include questions regarding our tax filing positions, including the timing and amount of deductions and the allocation of income among various tax jurisdictions. At any one time, multiple tax years are subject to audit by the various tax authorities. In evaluating the tax benefits associated with our various tax filing positions, we record a tax benefit for uncertain tax positions using the highest cumulative tax benefit that is more likely than not to be realized. A number of years may elapse before a particular matter for which we have established a liability is audited and effectively settled. We adjust our liability for unrecognized tax benefits in the period in which we determine the issue is effectively settled with the tax authorities, the statute of limitations expires for the relevant taxing authority to examine the tax position, or when more information becomes available. We include our liability for unrecognized tax benefits, including accrued penalties and interest, in income taxes payable on our consolidated balance sheets and in income tax expense in our consolidated statements of operations. Comprehensive (loss) income: We follow the provisions of ASC 220, Reporting Comprehensive Income, which establishes standards for reporting and displaying comprehensive income and its components. Comprehensive (loss) income reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. For us, comprehensive (loss) income represents net income (loss) adjusted for foreign currency translation adjustments and unrealized gains and losses on available-for-sale securities. The foreign currency translation adjustment included in comprehensive (loss) income has not been tax affected, as the investments in foreign affiliates are deemed to be permanent. In accordance with ASC 220 and ASU 2011-05, we disclose comprehensive (loss) income on a separate consolidated statement of comprehensive income. Product design and development: All expenses related to product design and development are charged to operations as incurred. Our product development activities include the enhancement of existing products and the development of new products. Advertising costs: We expense advertising costs as incurred. Advertising expenses were $1,584, $1,843 and $1,895 for fiscal years 2013, 2012 and 2011, respectively. Shipping and handling costs: Shipping and handling costs collected from our customers in connection with our sales are recorded as revenue. We record shipping and handling costs as a component of cost of sales at the time the product is shipped. Earnings per share (“EPS”): Basic EPS is computed by dividing income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution which may occur if securities or other obligations to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock which share in our earnings. The following is a reconciliation of the income and common stock share amounts used in the calculation of basic and diluted EPS for the fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011:
Options outstanding to purchase 2,672, 1,611 and 1,655 shares of common stock with a weighted average exercise price of $15.09, $19.17 and $19.23 per share during the fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011, respectively, were not included in the computation of diluted earnings per share because the weighted average exercise price of those instruments exceeded the average market price of the common shares during the year. Share-based compensation: We account for share-based compensation in accordance with ASC 718, Compensation-Stock Compensation. Under the fair value recognition provisions of ASC 718, we measure share-based compensation cost at the grant date based on the fair value of the award and recognize the compensation expense over the requisite service period, which is the vesting period. See Note 9 for additional information and the assumptions we use to calculate the fair value of share-based employee compensation. Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. The ASU amends guidance for the presentation of comprehensive income. The amended guidance requires an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate but consecutive statements. The previous option to report other comprehensive income and its components in the statement of shareholders’ equity has been eliminated. Although the new guidance changes the presentation of comprehensive income, there are no changes to the components recognized in net income or other comprehensive income under existing guidance. In the first quarter of fiscal 2013, we revised our presentation of comprehensive income to conform to the guidance in this ASU. In September 2011, the FASB issued ASU 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment. Under this new standard, entities testing goodwill for impairment now have an option of performing a qualitative assessment before having to calculate the fair value of a reporting unit. If an entity determines, on the basis of qualitative factors, it is more-likely-than-not the fair value of the reporting unit is less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. This ASU is effective for impairment tests after April 29, 2012. The adoption of this standard did not have an impact on our consolidated results of operations or financial condition, as this ASU impacts only the analysis performed. In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The amended guidance gives entities the option to perform a qualitative impairment assessment to determine whether it is more-likely-than-not an indefinite-lived intangible asset is impaired. An entity must identify and evaluate changes in economic, industry and entity-specific events and circumstances affecting the significant inputs used to determine the fair value of an indefinite-lived intangible asset and whether it is more-likely-than-not the fair value exceeds its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this amended guidance is not expected to have an impact on our consolidated results of operations or financial condition, as the ASU impacts only the analysis to be performed. |

| Segment Reporting | Segment Reporting We have organized our business into five segments which meet the definition of reportable segments under ASC 280-10, Segment Reporting: Commercial, Live Events, Schools and Theatres, Transportation, and the International business unit. These segments are based on the type of customer and geography. Our Commercial business unit primarily consists of sales of our video, Galaxy® and Fuelight™ product lines to resellers (primarily sign companies), outdoor advertisers, national retailers, quick-serve restaurants, casinos and petroleum retailers. Our Live Events business unit primarily consists of sales of integrated scoring and video display systems to college and professional sports facilities and convention centers and sales of our mobile display technology to video rental organizations and other live events type venues. Our Schools and Theatres business unit primarily consists of sales of scoring systems, Galaxy® displays and video display systems to primary and secondary education facilities and sales of our Vortek® automated rigging systems for theatre applications. Our Transportation business unit primarily consists of sales of our Vanguard® and Galaxy® product lines to governmental transportation departments, airlines and other transportation related customers. Our International business unit consists of sales of all product lines outside the United States and Canada. Segment reports present results through contribution margin, which is comprised of gross profit less selling costs. Segment profit excludes general and administration expense, product development expense, interest income and expense, non-operating income and income tax expense. Assets are not allocated to the segments. Depreciation and amortization, excluding the portion related to non-allocated costs, are allocated to each segment based on various financial measures. In general, segments follow the same accounting policies as those described in Note 1. Unabsorbed costs of domestic field sales and services infrastructure, including most field administrative staff, are allocated to the Commercial, Live Events, Transportation, and Schools and Theatres business units based on cost of sales. Shared manufacturing, building and utilities, and procurement costs are allocated based on payroll dollars, square footage and various other financial measures. We do not maintain information on sales by products; therefore, disclosure of such information is not practical. The following table sets forth certain financial information for each of our five operating segments for the periods indicated:
No single geographic area comprises a material amount of net sales or long-lived assets net of accumulated depreciation other than the United States. The following table presents information about net sales and long-lived assets in the United States and elsewhere:
We have numerous customers worldwide for sales of our products and services; therefore, we are not economically dependent on a limited number of customers for the sale of our products and services. |

| Marketable Securities | Marketable Securities We have a cash management program which provides for the investment of cash balances not used in current operations. We classify our investments in marketable securities as available-for-sale in accordance with the provisions of ASU 320, Investments – Debt and Equity Securities. Marketable securities classified as available-for-sale are reported at fair value with unrealized gains or losses, net of tax, reported in accumulated other comprehensive (loss) income. As it relates to fixed income marketable securities, we do not intend to sell any of these investments, and it is not more-likely-than-not we will be required to sell any of these investments before recovery of the entire amortized cost basis. The cost of securities sold is based on the specific identification method. Where quoted market prices are not available, we use the market price of similar types of securities traded in the market to estimate fair value. As of April 27, 2013 and April 28, 2012, our available-for-sale securities consisted of the following:
Realized gains or losses on investments are recorded in our consolidated statements of operations within other (expense) income, net. Upon the sale of a security classified as available-for-sale, the security’s specific unrealized gain (loss) is reclassified out of "accumulated other comprehensive (loss) income” into earnings based on the specific identification method. In the fiscal years ended April 27, 2013 and April 28, 2012, the reclassifications from accumulated other comprehensive (loss) income to net assets were immaterial. Realized gains and losses on sales and maturities of investments were immaterial in the fiscal years ended April 27, 2013 and April 28, 2012. All available-for-sale securities are classified as current assets, as they are readily available to support our current operating needs. The contractual maturities of available-for-sale debt securities as of April 27, 2013 were as follows:

| Goodwill and Intangible Assets Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Long-Lived Assets | Long-Lived Assets Goodwill and other intangible assets: We account for goodwill and intangible assets in accordance with ASC 350, Goodwill and Other Intangible Assets. Under these provisions, goodwill is not amortized but is tested for impairment on at least an annual basis. Impairment testing is required more often than annually if an event or circumstance indicates an impairment or a decline in value may have occurred. Such circumstances could include, but are not limited to, a worsening trend of orders and sales without a corresponding way to preserve future cash flows or a significant decline in our stock price. In conducting our impairment testing, we compare the fair value of each of our business units (reporting unit) to the related carrying value. If the fair value of a reporting unit exceeds its carrying value, goodwill is not impaired. If the carrying value of a reporting unit exceeds its fair value, an impairment loss is measured and recognized. We utilize an income approach to estimate the fair value of each reporting unit. We selected this method because we believe it most appropriately measures our income producing assets. We considered using the market approach and cost approach, but concluded they were not appropriate in valuing our reporting units given the lack of relevant and available market comparisons. The income approach is based on the projected cash flows, which are discounted to their present value using discount rates which consider the timing and risk of the forecasted cash flows. We believe that this approach is appropriate because it provides a fair value estimate based upon the reporting units’ expected long-term operating cash performance. This approach also mitigates the impact of the cyclical trends occurring in the industry. Fair value is estimated using internally-developed forecasts and assumptions. The discount rate used is the average estimated value of a market participant’s cost of capital and debt, derived using customary market metrics. Other significant assumptions include terminal value margin rates, future capital expenditures, and changes in future working capital requirements. We also compare and reconcile our overall fair value to our market capitalization. Although there are inherent uncertainties related to the assumptions used and to our application of these assumptions to this analysis, we believe the income approach provides a reasonable estimate of the fair value of our reporting units. The foregoing assumptions to a large degree were consistent with our long-term performance, with limited exceptions. We believe our future investments for capital expenditures as a percent of revenue will remain similar to the historical rates as a percentage of sales in future years with investments related to equipment replacements, new product line manufacturing equipment needs, and to keep our information technology infrastructure robust, and we believe long-term receivables will decrease as we grow. We also have assumed through the recent economic downturn, our markets have not contracted for the long term; however, it may be a number of years before they fully recover. These assumptions could deviate materially from actual results. We perform an analysis of goodwill on an annual basis. We completed this annual analysis during our third quarter of each fiscal year, based on the goodwill amount as of the first business day of our third quarter in fiscal 2013, 2012, and 2011. The result of our analysis indicated that no goodwill impairment existed for each fiscal year. The changes in the carrying amount of goodwill related to each reportable segment for the fiscal year ended April 27, 2013 were as follows:
As required by ASC 350, intangibles with finite lives are amortized. We evaluate indefinite lived assets for impairment annually and whenever events or changes in circumstances indicate their carrying value may not be recoverable. The net value of intangible assets is shown on our consolidated balance sheets. Estimated amortization expense based on intangibles as of April 27, 2013 is $228 for each of the fiscal years 2014 through 2016 and $95 for fiscal 2017. The following table sets forth the gross carrying amount and accumulated amortization of intangible assets by major intangible class as of April 27, 2013 and April 28, 2012:
Impairment of long-lived assets: We recorded a pretax asset impairment charge of $64, $538 and $355 for the fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011, respectively for other long-lived assets including property and equipment. The impairment charges related to technology or equipment obsoleted due to technology improvements or to custom demo equipment with no re-sale value. Impairment charges during fiscal 2013 were included primarily in selling expense. |

| Receivables [Abstract] | |
| Receivables | Receivables We sell our products throughout the United States and in certain foreign countries on credit terms we establish for each customer. On the sale of certain products, we have the ability to file a contractor’s lien against the product installed as collateral and to file claims against surety bonds to protect our interest in receivables. Foreign sales are at times secured by irrevocable letters of credit or bank guarantees. Accounts receivable are reported net of an allowance for doubtful accounts of $2,729 and $2,398 at April 27, 2013 and April 28, 2012, respectively. We make estimates regarding the collectability of our accounts receivable, long-term receivables, costs and estimated earnings in excess of billings and other receivables. In evaluating the adequacy of our allowance for doubtful accounts, we analyze specific balances, customer creditworthiness, changes in customer payment cycles, and current economic trends. If the financial condition of any customer were to deteriorate, resulting in an impairment of its ability to make payments, additional allowances may be required. We charge off receivables at such time as it is determined collection will not occur. Charge offs of receivables and our allowance for doubtful accounts related to financing receivables are not material to our financial results. In connection with certain sales transactions, we have entered into sales contracts with installment payments exceeding six months and sales-type leases. The present value of these contracts and leases is recorded as a receivable as the revenue is recognized in accordance with generally accepted accounting principles, and profit is recognized to the extent the present value is in excess of cost. We generally retain a security interest in the equipment or in the cash flow generated by the equipment until the contract is paid. The present value of long-term contracts and lease receivables, including accrued interest and current maturities, was $16,132 and $18,452 as of April 27, 2013 and April 28, 2012, respectively. Contract and lease receivables bearing annual interest rates of 5.8 to 10.0 percent are due in varying monthly, quarterly or annual installments through July 2022. The face amount of long-term receivables was $18,731 as of April 27, 2013 and $21,494 as of April 28, 2012. Included in accounts receivable as of April 27, 2013 and April 28, 2012 was $803 and $783, respectively, of retainage on construction-type contracts, all of which is expected to be collected in one year. |

| Debt Disclosure [Abstract] | |||||||||
| Financing Agreements | Financing Agreements We have a credit agreement with a U.S. bank providing for a $35.0 million line of credit and includes up to $15.0 million for standby letters of credit. The line of credit is due on November 15, 2013. The interest rate ranges from LIBOR plus 125 basis points to LIBOR plus 175 basis points depending on the ratio of our interest-bearing debt to EBITDA. EBITDA is defined as net income before income taxes, interest expense, depreciation and amortization. The effective interest rate was 1.5 percent at April 27, 2013. We are assessed a loan fee equal to 0.125 percent per annum of any non-used portion of the loan. As of April 27, 2013, there were no advances under the line of credit. The credit agreement is unsecured and requires us to be in compliance with the following financial ratios:
We have an additional credit agreement with another U.S. bank which expires on November 15, 2013 and is intended to support our credit needs outside of the United States. The facility provides for a $35.0 million line of credit and includes facilities for letters of credit and bank guarantees and to secure foreign loans for our international subsidiaries. The U.S. credit agreement is unsecured and is cross collateralized with the $35.0 million line of credit described above. It contains the same covenants as the credit agreement above. As of April 27, 2013, there were no advances under the line of credit. We were in compliance with all applicable covenants as of April 27, 2013 and April 28, 2012.

| Shareholders' Equity and Share-Based Compensation | Shareholders’ Equity and Share-Based Compensation Common stock: Our authorized shares of 120,000 consist of 115,000 shares of common stock and 5,000 shares of “undesignated stock.” Our Board of Directors has the power to issue any or all of the shares of undesignated stock without shareholder approval, including the authority to establish the rights and preferences of the undesignated stock. Each outstanding share of our common stock includes one common share purchase right. Each right entitles the registered holder to purchase from us one one-tenth of one share of common stock at a price of $100 per common share, subject to adjustment and the terms of the shareholder rights agreement under which the dividend was declared and paid. The rights become exercisable immediately after the earlier of (i) 10 business days following a public announcement where a person or group has acquired beneficial ownership of 15 percent or more of our outstanding common shares (subject to certain exclusions) or (ii) 10 business days following the commencement or announcement of an intention to make a tender offer or exchange offer for our common shares, the consummation of which would result in the beneficial ownership by a person or group of 15 percent or more of our outstanding common shares. The rights expire on November 19, 2018, which date may be extended by our Board subject to certain additional conditions. Stock incentive plans: During fiscal 2008, we established the 2007 Stock Incentive Plan (“2007 Plan”) and ceased granting options under the 2001 Incentive Stock Option Plan, and the 2001 Outside Directors Option Plan (“2001 Plans”). The 2007 Plan provides for the issuance of stock-based awards, including stock options, restricted stock, restricted stock units and deferred stock, to employees, directors and consultants. Stock options issued to employees under the plans generally have a 10-year life, an exercise price equal to the fair market value on the grant date and a five-year vesting period. Stock options granted to independent directors under these plans have a seven-year life and an exercise price equal to the fair market value on the date of grant. Stock options granted to independent directors prior to fiscal 2010 vest over three years, and options granted in or after fiscal 2010 vest in one year. The restricted stock granted to independent directors vests in one year, provided that they remain on the Board. Restricted stock units are granted to employees and have a five-year vesting period. As with stock options, restricted stock and restricted stock unit ownership cannot be transferred during the vesting period. At April 27, 2013, the aggregate number of shares available for future grant under the 2007 plan for stock options and restricted stock awards was 798 shares. Full value awards such as restricted stock and restricted stock unit awards reduce the number of shares available for issuance by a factor of two, or if such an award were forfeited or terminated without delivery of the shares, the number of shares again become eligible for issuance would be multiplied by a factor of two. Although the 2001 Plans remain in effect for options outstanding, no new options can be granted under these plans. Restricted stock and restricted stock units: We issue restricted stock to our non-employee directors and restricted stock units to employees. The fair value of restricted stock and our restricted stock unit awards are measured on the grant date based on the market value of our common stock. The related compensation expense as calculated under ASC 718, net of estimated forfeitures, is recognized over the applicable vesting period. Unrecognized compensation expense related to the restricted stock and restrict stock unit awards was approximately $2,080 at April 27, 2013, which is expected to be recognized over a weighted-average period of 3.3 years. The total fair value of restricted stock vested was $666, $511, and $288 for fiscal years 2013, 2012, and 2011, respectively. A summary of nonvested restricted stock and restricted stock units for the years ended April 27, 2013, April 28, 2012 and April 30, 2011 is as follows:
Stock Options: We issue incentive stock options to our employees and non-qualified stock options to our independent directors. A summary of stock option activity under all stock option plans during the fiscal year ended April 27, 2013 is as follows:
The aggregate intrinsic value of stock options represents the difference between the exercise price of stock options and the fair market value of the underlying common stock at day's end for all in-the-money options. We define in-the-money options at April 27, 2013 as options having exercise prices lower than the $9.57 per share market price of our common stock. There were in-the-money options to purchase 917 shares exercisable at April 27, 2013. The total intrinsic value of options exercised during fiscal years 2013, 2012, and 2011 was $562, $624, and $1,945, respectively. The total fair value of stock options vested was $1,898, $2,497, and $2,628 for fiscal years 2013, 2012, and 2011, respectively. We estimate the fair value of stock options granted using the Black-Scholes option valuation model. We recognize the fair value of the stock options on a straight-line basis as compensation expense. All options are recognized over the requisite service periods of the awards, which are generally the vesting periods. The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options having no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility. ASC 718 requires us to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We use historical data to estimate pre-vesting option forfeitures and record share-based compensation expense only for those awards expected to vest. The following factors are the significant assumptions used in the computation of fair value of options: Expected life. The expected life of options granted represents the period of time they are expected to be outstanding. We estimate the expected life of options granted based on historical exercise patterns, which we believe are representative of future behavior. We have examined our historical pattern of option exercises in an effort to determine if there were any discernible patterns of activity based on certain demographic characteristics. Demographic characteristics tested included age, salary level, job level and geographic location. We have determined there were no meaningful differences in option exercise activity based on the demographic characteristics tested. Expected volatility. We estimate the volatility of our common stock at the date of grant based on historical volatility consistent with ASC 718 and SEC Staff Accounting Bulletin No. 107, Share Based Payments. Our decision to use historical volatility instead of implied volatility was based upon analyzing historical data along with the lack of availability of history of actively traded options on our common stock. Risk-free interest rate. The rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a term similar to the expected life of the options. Dividend yield. We use an expected dividend yield consistent with our dividend yield over the period of time we have paid dividends. The following table provides the weighted-average fair value of options granted and the related assumptions used in the Black-Scholes model:
Employee stock purchase plan: We have an employee stock purchase plan (“ESPP”), which enables employees after six months of continuous employment to elect, in advance and semi-annually, to contribute up to 15 percent of their compensation, subject to certain limitations, toward the purchase of our common stock at a purchase price equal to 85 percent of the lower of the fair market value of the common stock on the first or last day of the participation period. The ESPP plan requires participants to hold any share purchased under the plan for a minimum period of one year after the date of purchase. Compensation expense recognized on shares issued under our ESPP is based on the value of a traded option to purchase shares of our stock at a 15 percent discount to the stock price. The total number of shares reserved under the ESPP is 2,500. The number of shares of common stock issued under the ESPP totaled 214, 160, and 205 shares in fiscal 2013, 2012, and 2011, respectively. The number of shares of common stock reserved for future employee purchases under the ESPP totaled 1,185 shares at April 27, 2013. The ESPP is intended to qualify under Section 423 of the Internal Revenue Code of 1986. Total share-based compensation expense: As of April 27, 2013, there was $5,379 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted under all equity compensation plans. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures. We expect to recognize the cost over a weighted-average period of 3.1 years. The following table presents a summary of the share-based compensation expense by equity type as follows:
A summary of the share-based compensation expenses for stock options, restricted stock, restricted stock units and shares issued under the ESPP for the fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011 is as follows:
We received $1,316 in cash from option exercises under all share-based payment arrangements for the fiscal year ended April 27, 2013. The tax benefit related to non-qualified options and restricted stock units under all share-based payment arrangements totaled $346, $325, and $239 for fiscal years 2013, 2012, and 2011, respectively. |

| Compensation and Retirement Disclosure [Abstract] | |
| Employee Benefit Plans | Employee Benefit Plans We sponsor a 401(k) savings plan under which eligible U.S. employees may choose to make voluntary contributions of such employee's compensation on a pretax basis, subject to certain Internal Revenue Service (IRS) limits. We make matching contributions equal to 25 percent (50 percent prior to August 1, 2010 and after January 29, 2011) of the employee's qualifying contribution up to six percent of such employee's compensation plus other discretionary contributions as authorized by our Board of Directors. Employees are eligible to participate upon completion of one year of service if they have attained the age of 21 and have worked more than 1000 hours during such plan year. We contributed $1,713, $1,618 and $905 to the plan for fiscal years 2013, 2012, and 2011, respectively. We have unfunded deferred compensation agreements with certain officers and a former director under which interest is credited each year to each participant’s account in an amount equal to the five-year Treasury note rate as of January 1 of each plan year. Total amounts accrued for these plans as of April 27, 2013 and April 28, 2012 were $629 and $625, respectively. Contributions for each of the fiscal years 2013, 2012, and 2011 were $23, $23 and $22, respectively. The amounts accrued under the plans are not funded and are subject to the claims of the participants’ creditors. Participants may elect various forms of withdrawals upon retirement, including a lump sum distribution or annual payments over five or 10 years. |

| Income Taxes | Income Taxes We are subject to U.S. Federal income tax as well as the income taxes of multiple state jurisdictions. As a result of the completion of examinations by the Internal Revenue Service on prior years and the expiration of statutes of limitations, fiscal years 2010, 2011 and 2012 are the only years remaining open under statutes of limitations. Certain subsidiaries are also subject to income tax in several foreign jurisdictions which have open tax years varying by jurisdiction beginning in fiscal 2005. On January 2, 2013, the President signed into law The American Taxpayer Relief Act of 2012. Under prior law, a taxpayer was entitled to a research tax credit for qualifying amounts paid or incurred on or before December 31, 2011. The 2012 Taxpayer Relief Act extends the research credit for two years to December 31, 2013. The extension of the research credit is retroactive and includes amounts paid or incurred after December 31, 2011. As a result of the retroactive extension, we recognized approximately $1,804 in tax benefits for the credit during fiscal year 2013. Income tax expense (benefit) consisted of the following:
A reconciliation of the provision for income taxes and the amount computed by applying the federal statutory rate to income before income taxes is as follows:
We operated under a tax holiday in China which expired in fiscal 2012. As noted above, the expiration of this tax holiday caused a $249 decrease in our income tax expense in fiscal 2012. The pretax income attributable to domestic and foreign operations was as follows:
The components of the net deferred tax asset were as follows:
We review deferred tax assets, including net operating losses, and to the extent we believe the asset may not be realized, we recognize a valuation allowance. At April 27, 2013 and April 28, 2012, we had recorded no valuation allowances as we believe our deferred tax assets will be fully realized based upon our estimates of the future taxable income. If our estimates of future taxable income are not met in future periods, a valuation allowance for some of these deferred tax assets may be required. We have not recorded U.S. deferred income taxes on certain of our non-U.S. subsidiaries’ undistributed earnings, as such amounts are intended to be reinvested outside the United States indefinitely. However, should we change our business and tax strategies in the future and decide to repatriate a portion of these earnings to one of our U.S. subsidiaries, including cash maintained by these non-U.S. subsidiaries, additional U.S. tax liabilities would be incurred. It is not practical at this time to estimate the amount of additional U.S. tax liabilities we would incur. The following presents the classification of the net deferred tax asset on the accompanying consolidated balance sheets:
We account for uncertainties in tax positions under the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes, an Interpretation of SFAS No. 109. ASC 740-10 creates a single model to address uncertainty in tax positions and clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. ASC 740-10 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The following table provides a reconciliation of changes in unrecognized tax benefits for fiscal 2013, 2012 and 2011:
We recognized an expense (benefit) of $10, $(1) and $(16) in net interest and penalties during the years ended April 27, 2013, April 28, 2012 and April 30, 2011, respectively. Interest and penalties recognized are recorded in income taxes in our consolidated statements of operations. We had accrued $11 and $24 in net interest or penalties as of April 27, 2013 and April 28, 2012, respectively. |

| Fair Value Disclosures [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value Measurement | Fair Value Measurement ASC 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. It also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The fair value hierarchy within ASC 820 distinguishes between the following three levels of inputs which may be utilized when measuring fair value. Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Observable inputs other than quoted prices included within Level 1 for the assets or liabilities, either directly or indirectly (for example, quoted market prices for similar assets and liabilities in active markets or quoted market prices for identical assets or liabilities in markets not considered to be active, inputs other than quoted prices that are observable for the asset or liability, or market-corroborated input.) Level 3 - Unobservable inputs supported by little or no market activity based on our own assumptions used to measure assets and liabilities. The fair values for fixed-rate contracts receivable are estimated using a discounted cash flow analysis based on interest rates currently being offered for contracts with similar terms to customers with similar credit quality. The carrying amounts reported on our consolidated balance sheets for contracts receivable approximate fair value and have been categorized as a Level 2 fair value measurement. The carrying amounts reported for variable rate long-term marketing obligations approximate fair value. Fair values for fixed-rate long-term marketing obligations are estimated using a discounted cash flow calculation which applies interest rates currently being offered for debt with similar terms and underlying collateral. The total carrying value of long-term marketing obligations reported on our consolidated balance sheets approximates fair value and has been categorized as a Level 2 fair value measurement. The following table sets forth by Level within the fair value hierarchy our financial assets and liabilities accounted for at fair value on a recurring basis at April 27, 2013 and April 28, 2012 according to the valuation techniques we used to determine their fair values. There have been no transfers of assets or liabilities among the fair value hierarchies presented.
The following methods and assumptions were used to estimate the fair value of each class of financial instrument. There have been no changes in the valuation techniques used by us to value our financial instruments. Cash and cash equivalents: Consists of cash on hand in bank deposits and highly liquid investments, primarily money market accounts. The fair value was measured using quoted market prices in active markets. The carrying amount approximates fair value. Restricted cash: Consists of cash and cash equivalents held in bank deposit accounts to secure issuances of foreign bank guarantees. The fair value of restricted cash was measured using quoted market prices in active markets. The carrying amount approximates fair value. Certificates of deposit: Consists of time deposit accounts with original maturities of less than three years and various yields. The fair value of these securities was measured based on valuations observed in less active markets than Level 1 investments from a third-party financial institution. The carrying amount approximates fair value. U.S. Government securities: Consists of U.S. Government treasury bills, notes, and bonds with original maturities of less than three years and various yields. The fair value of these securities was measured using quoted market prices in active markets. U.S. Government sponsored entities: Consist of Fannie Mae and Federal Home Loan Bank investment grade debt securities trading with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The fair value of these securities was measured based on valuations observed in less active markets than Level 1 investments. The contractual maturities of these investments vary from one month to three years. Municipal obligations: Consist of investment grade municipal bonds trading with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The contractual maturities of these investments vary from two to three years. The fair value of these bonds was measured based on valuations observed in less active markets than Level 1 investments. Derivatives – currency forward contracts: Consists of currency forward contracts trading with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. The fair value of these securities was measured based on a valuation from a third-party bank. See Note 14 for more information regarding our derivatives. The fair value measurement standard also applies to certain non-financial assets and liabilities measured at fair value on a nonrecurring basis. For example, certain long-lived assets such as goodwill, intangible assets and property, plant and equipment are measured at fair value in connection with business combinations or when an impairment is recognized and the related assets are written down to fair value. We did not make any material business combinations or recognize significant impairment losses during fiscal 2013 or fiscal 2012. |

| Derivative Instruments and Hedging Activities Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivative Financial Instruments | Derivative Financial Instruments We utilize derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates on those transactions denominated in currencies other than our functional currency, which is the U.S. dollar. We enter into currency forward contracts to manage these economic risks. We account for all derivatives on the balance sheet within other assets or accounts payable measured at fair value, and changes in fair values are recognized in earnings unless specific hedge accounting criteria are met for cash flow or net investment hedges. As of April 27, 2013 and April 28, 2012, we had not designated any of our derivative instruments as accounting hedges, and thus we recorded the changes in fair value in other (expense) income, net. The foreign currency exchange contracts in aggregated notional amounts in place to exchange United States Dollars at April 27, 2013 and April 28, 2012 were as follows:
As of April 27, 2013 and April 28, 2012, there was a net asset (liability) of $7 and $(95), respectively, representing the fair value of foreign currency exchange forward contracts, which was determined using Level 2 inputs from a third-party bank. |

| Commitments and Contingencies Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Commitments and Contingencies | Commitments and Contingencies Litigation: We are a party to legal proceedings and claims that arise during the ordinary course of business. We review our legal proceedings and claims, regulatory reviews and inspections and other legal matters on an ongoing basis and follow appropriate accounting guidance when making accrual and disclosure decisions. We establish accruals for those contingencies when the incurrence of a loss is probable and can be reasonably estimated, and we disclose the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for our financial statements to not be misleading. We do not record an accrual when the likelihood of loss has been incurred is probable, but the amount cannot be reasonably estimated, or when the loss is believed to be only reasonably possible or remote, although disclosures will be made for material matters as required by ASC 450-20, Loss Contingencies. Our assessment of whether a loss is reasonably possible or probable is based on our assessment and consultation with legal counsel regarding the ultimate outcome of the matter following all appeals. As of April 27, 2013, we did not believe there was a reasonable possibility any material loss for these various claims or legal actions, including reviews, inspections or other legal proceedings, if any, had been incurred. Accordingly, no accrual or disclosure of a potential range of loss has been made related to these matters. In the opinion of management, the ultimate liability of all unresolved legal proceedings is not expected to have a material effect on our financial position, liquidity or capital resources. Guarantees: In connection with the sale of equipment to various customers, we have entered into contractual arrangements whereby we agreed to repurchase equipment at the end of the lease term at a fixed price. Our total obligations under these fixed price arrangements were $1,285 as of April 27, 2013 and April 28, 2012. We have recognized a guarantee liability in accrued expenses for the amount of $185 in accordance with the provisions of ASC 460, Guarantees, in connection with these arrangements. Warranties: We offer a standard parts coverage warranty for periods varying from one to five years for most of our products. We also offer additional types of warranties including on-site labor, routine maintenance and event support. In addition, the terms of warranties on some installations can vary from one to 10 years. The specific terms and conditions of these warranties vary primarily depending on the type of the product sold. We estimate the costs incurred under the warranty obligations and record a liability in the amount of such estimated costs at the time the revenue is recognized. Factors affecting our estimate of the cost of our warranty obligations include historical experience and expectations of future conditions. We periodically assess the adequacy of our recorded warranty reserves and, to the extent we experience any changes in warranty claim activity or costs associated with servicing those claims, our warranty obligation is adjusted accordingly. Changes in our warranty liability for the fiscal years ended April 27, 2013 and April 28, 2012 consisted of the following:
Performance guarantees: We have entered into standby letters of credit and surety bonds with financial institutions relating to the guarantee of future performance on contracts, primarily construction type contracts. As of April 27, 2013, we had outstanding letters of credit and surety bonds in the amount of $6,169 and $13,287, respectively. Performance guarantees are issued to certain customers to guarantee the operation and installation of the equipment and our ability to complete a contract. These performance guarantees have various terms, which are generally less than one year. Leases: We lease vehicles, office space and various equipment for various sales and service locations throughout the world, including manufacturing space in the United States and China. Some of these leases, including the lease for manufacturing facilities in Sioux Falls, South Dakota, include provisions for extensions or purchase. The lease for the facilities in Sioux Falls, South Dakota can be extended for an additional three years past its current term, which ends December 31, 2016, and it contains an option to purchase the property subject to the lease from January 1, 2015 to December 31, 2016 for $8,400, which approximates fair value. If the lease is extended, the purchase option increases to $8,600 for the year ending December 31, 2017 and $8,800 for the year ending December 31, 2018. Rental expense for operating leases was $2,749, $3,159 and $3,738 for the fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011, respectively. Future minimum payments under noncancelable operating leases, excluding executory costs such as management and maintenance fees, with initial or remaining terms of one year or more consisted of the following at April 27, 2013:
Purchase commitments: From time to time, we commit to purchase inventory, advertising, and various other products and services over periods that extend beyond one year. As of April 27, 2013, we were obligated under the following conditional and unconditional purchase commitments, which included $1,000 in conditional purchase commitments.

| Noncontrolling Interest [Abstract] | |
| Investments in Affiliates and Related Party Transactions | Investments in Affiliates and Related Party Transactions We owned a seven percent interest in Outcast as of April 27, 2013 and April 28, 2012. Prior to February 2011, our interest in Outcast was 37.5 percent. As a result of certain transactions during fiscal 2011, Outcast ceased being an equity method investee and, as of April 30, 2011, was a cost method investee with a carrying balance of zero. These transactions during fiscal 2011 resulted in our release under our guarantees of certain debt of Outcast and resulted in the repayment of various loans and advances we had made to Outcast and related parties of Outcast. These transactions resulted in a gain of approximately $605 during fiscal 2011, which is included in other income. |

Nature of Business and Summary of Significant Accounting Policies (Policies)

12 Months Ended | ||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
|
Apr. 27, 2013
|
|||||||||||||||||||||
| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |||||||||||||||||||||
| Nature of business | Nature of business: Daktronics, Inc. and its subsidiaries are engaged principally in the design, manufacture and sale of a wide range of electronic display systems and related products which are sold in a variety of markets throughout the world and the rendering of related maintenance and professional services. Our products are designed primarily to inform and entertain people through the communication of content. |
||||||||||||||||||||
| Fiscal year | Fiscal year: We operate on a 52 to 53 week fiscal year, with our fiscal year ending on the Saturday closest to April 30 of each year. When April 30 falls on a Wednesday, the fiscal year ends on the preceding Saturday. The fiscal years ended April 27, 2013, April 28, 2012 and April 30, 2011 each consisted of 52 weeks. Within each fiscal year, each quarter is comprised of 13 week periods following the beginning of each fiscal year. In each 53 week year, each of the last three quarters is comprised of a 13 week period, and an additional week is added to the first quarter of that fiscal year. |
||||||||||||||||||||
| Principles of consolidation | Principles of consolidation: The consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries – Daktronics France SARL; Daktronics Shanghai, Ltd.; Daktronics GmbH; Daktronics UK, Ltd.; Daktronics HK Limited; Daktronics International Limited; Daktronics Canada, Inc.; Daktronics Beijing, Ltd.; Daktronics Australia Pty Ltd.; Daktronics Installation; Daktronics Japan, Inc.; Daktronics Brazil, Ltda.; Daktronics Singapore Pte. Ltd., and Daktronics Spain S.L. Intercompany balances and transactions have been eliminated in consolidation. Investments in affiliates over which we have significant influence are accounted for by the equity method. As of April 27, 2013 and April 28, 2012, we did not have any investments accounted for by the equity method. Prior to April 30, 2011, as explained in Note 16, we had various investments accounted for under the equity method. Investments in affiliates as to which we do not have the ability to exert significant influence over their operating and financing activities are accounted for under the cost method of accounting. We have evaluated our relationships with affiliates and have determined that these entities are either not variable interest entities or, in the case of variable interest entities, we are not the primary beneficiary and therefore they are not required to be consolidated in our consolidated financial statements. The equity method requires us to report our share of losses up to our equity investment amount, including any financial support made or committed to. At such time the equity investment is reduced to zero, we recognize losses to the extent of and as an adjustment to the other investments in the affiliate in order of seniority or priority in liquidation. Our proportional share of the respective affiliates' earnings or losses is included in other (expense) income in our consolidated statements of operations. |
||||||||||||||||||||
| Use of estimates | Use of estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the estimated total costs on construction-type contracts, estimated costs to be incurred for product warranties, excess and obsolete inventory, the reserve for doubtful accounts, share-based compensation, goodwill impairment and income taxes. Changes in estimates are reflected in the periods in which they become known. |
||||||||||||||||||||
| Cash and cash equivalents | Cash and cash equivalents: All highly liquid investments with maturities of three months or less at the date of purchase are considered to be cash equivalents and consist primarily of government repurchase agreements, savings accounts and money market accounts that are carried at cost, which approximates fair value. We maintain our cash in bank deposit accounts, the balances of which at times may exceed federally insured limits. |
||||||||||||||||||||
| Restricted cash | Restricted cash: Restricted cash consists of deposits to secure bank guarantees issued by our foreign subsidiaries. |
||||||||||||||||||||
| Inventories | Inventories: Inventories are stated at the lower of cost (first-in, first-out method) or market. Market is determined on the basis of estimated net realizable values. |
||||||||||||||||||||
| Revenue recognition | Revenue recognition: Net sales are reported net of estimated sales returns and exclude sales taxes. We estimate our sales returns reserve based on historical return rates and analysis of specific accounts. |
||||||||||||||||||||
| Revenue recognition - Long-term construction-type contracts | Long-term construction-type contracts: Earnings on construction-type contracts are recognized on the percentage-of-completion method, measured by the percentage of costs incurred to date to estimated total costs for each contract. Contract costs include all direct material and labor costs and those indirect costs related to contract performance. Indirect costs include charges for such items as facilities, engineering, and project management. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are probable and capable of being estimated. We combine contracts for accounting purposes when they are negotiated as a package with an overall profit margin objective, essentially represent an agreement to do a single project for a customer, involve interrelated construction activities, and are performed concurrently or sequentially. When a group of contracts is combined, revenue and profit are recognized uniformly over the performance of the combined projects. We segment revenues in accordance with contract segmenting criteria in Accounting Standards Codification (“ASC”) 650-35, Construction-Type and Production-Type Contracts. |
||||||||||||||||||||
| Revenue recognition - Equipment other than construction-type contracts | Equipment other than construction-type contracts: We recognize revenue on equipment sales, other than construction-type contracts, when title passes, which is usually upon shipment and then only if the terms of the arrangement are fixed and determinable and collectability is reasonably assured. We record estimated sales returns and discounts as a reduction of net sales in the same period revenue is recognized. |
||||||||||||||||||||
| Revenue recognition - Product maintenance | Product maintenance: In connection with the sale of our products, we also occasionally sell separately priced extended warranties and product maintenance contracts. The revenue related to such contracts is deferred and recognized ratably as net sales over the terms of the contracts, which vary up to 10 years. We record unrealized revenue in deferred revenue (billed or collected) in the liability section of the balance sheet. Deferred revenue (billed or collected) excludes unrealized revenue from contractual obligations to be billed by us in future periods. |
||||||||||||||||||||
| Revenue recognition - Services | Services: Revenues generated by us for services, such as event support, control room design, on-site training, equipment service and technical support of our equipment, are recognized as net sales when the services are performed. |
||||||||||||||||||||
| Revenue recognition - Multiple-element arrangements | Multiple-element arrangements: We generate revenue from the sale of equipment and related services, including customization, installation and maintenance services. In these limited cases, we provide some or all of such equipment and services to our customers under the terms of a single multiple-element sales arrangement. These arrangements typically involve the sale of equipment bundled with some or all of these services, but they may also involve instances in which we have contracted to deliver multiple pieces of equipment over time rather than at a single point in time. When a sales arrangement involves multiple elements, the items included in the arrangement (deliverables) are evaluated pursuant to ASC 605-25, Revenue Arrangements with Multiple Deliverables and ASC 605-35, to determine whether they represent separate units of accounting. We perform this evaluation at the inception of an arrangement and as we deliver each item in the arrangement. We first consider the separation criteria of ASC 605-35. Deliverables not within the scope of ASC 605-35 are evaluated for separation under ASC 605-25. For those elements falling under the guidance of ASC 605-25, we generally account for a deliverable (or a group of deliverables) separately if the delivered item(s) has standalone value to the customer and if we have given the customer a general right of return relative to the delivered item(s) and delivery or performance of the undelivered item(s) or service(s) is probable and substantially in our control. When items included in a multiple-element arrangement represent separate units of accounting, we allocate the arrangement consideration to the individual items based on their relative fair values. The amount of arrangement consideration allocated to the delivered item(s) is limited to the amount not contingent on us delivering additional products or services. Once we have determined the amount, if any, of arrangement consideration allocable to the delivered item(s), we apply the applicable revenue recognition policy to determine when and by which method such amount may be recognized as revenue. We generally determine if objective and reliable evidence of fair value for the items included in a multiple-element arrangement exists based on whether we have vendor-specific objective evidence ("VSOE") of the price for which we sell an item on a standalone basis. If we do not have VSOE for the item, we will use the price charged by a competitor selling a comparable product or service on a standalone basis to similarly situated customers, if available. If neither VSOE nor third party evidence is available, we use our best estimate of the selling price for that deliverable. |
||||||||||||||||||||
| Revenue recognition - Software | Software: We typically sell our proprietary software bundled with our video displays and certain other products, but we also sell our software separately. Pursuant to ASC 985-605, Software Revenue Recognition, revenues from software license fees on sales, other than construction-type contracts, are recognized when persuasive evidence of an agreement exists, delivery of the product has occurred, the fee is fixed and determinable, and collection is probable. For sales of software included in construction-type contracts, the revenue is recognized under the percentage-of-completion method starting when all of these criteria have been met. |
||||||||||||||||||||
| Revenue recognition - Long-term receivables and advertising rights | Long-term receivables and advertising rights: We occasionally sell and install our products at facilities in exchange for the rights to sell or to retain future advertising revenues. For these transactions, we recognize revenue for the amount of the present value of the future advertising payments if enough advertising is sold to obtain normal margins on the contract and we record the related receivable in long-term receivables. We recognize imputed interest as earned. On those transactions where we have not sold the advertising for the full value of the equipment at normal margins, we record the related cost of equipment as advertising rights. Revenue to the extent of the present value of the advertising payments is recognized in long-term receivables when it becomes fixed and determinable under the provisions of the applicable advertising contracts. At the time the revenue is recognized, costs of the equipment are recognized based on an estimate of overall margin expected. Any remaining costs are recorded in the costs of advertising rights. |
||||||||||||||||||||
| Property and equipment | Property and equipment: Property and equipment is stated at cost and depreciated principally on the straight-line method over the following estimated useful lives:
Leasehold improvements are depreciated over the lesser of the useful life of the asset or the term of the lease. |
||||||||||||||||||||
| Long-Lived Assets | Long-Lived Assets: Long-lived assets other than goodwill and indefinite-lived intangible assets, as described in Note 4, which are separately tested for impairment, are evaluated for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. When evaluating long-lived assets for potential impairment, we first compare the carrying value of the asset to the asset's estimated future cash flows (undiscounted and without interest charges). If the estimated future cash flows are less than the carrying value of the asset, we calculate an impairment loss. The impairment loss calculation compares the carrying value of the asset to the asset's estimated fair value. We recognize an impairment loss if the amount of the asset's carrying value exceeds the asset's estimated fair value. If we recognize an impairment loss, the adjusted carrying amount of the asset becomes its new cost basis. For a depreciable long-lived asset, the new cost basis will be depreciated (amortized) over the remaining useful life of that asset. Our impairment loss calculations contain uncertainties because they require management to make assumptions and to apply judgment to estimate future cash flows and asset fair values, including forecasting useful lives of the assets and selecting the discount rate that reflects the risk inherent in future cash flows. |
||||||||||||||||||||
| Software costs | Software costs: We capitalize certain costs incurred in connection with developing or obtaining internal-use software. Capitalized software costs are included in property and equipment on our consolidated balance sheets. Software costs that do not meet capitalization criteria are expensed immediately. |

| Foreign currency translation | Foreign currency translation: Our foreign subsidiaries use the local currency of their respective countries as their functional currency. The assets and liabilities of foreign operations are generally translated at the exchange rates in effect at the balance sheet date. The operating results of foreign operations are translated at weighted average exchange rates. The related translation gains or losses are reported as a separate component of shareholders’ equity in accumulated other comprehensive (loss) income. |
||||||||||||||||||||
| Income taxes | Income taxes: We account for income taxes under ASC 740, Income Taxes, which requires recognition of deferred tax liabilities and assets for the expected future tax consequences of events included in our financial statements or tax returns. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. ASC 740 requires the consideration of a valuation allowance for deferred tax assets if it is “more likely than not” some component or all of the benefits of deferred tax assets will not be realized. Tax rate changes are reflected in income during the period such changes are enacted. We have benefited from a tax holiday in China that expired in fiscal 2012. In fiscal 2012 and 2011, we realized a benefit of approximately $249 or $0.006 per share and $77 or $0.002 per share, respectively. Our income tax returns, like those of most companies, are periodically audited by U.S. federal, state and local and foreign tax authorities. These audits include questions regarding our tax filing positions, including the timing and amount of deductions and the allocation of income among various tax jurisdictions. At any one time, multiple tax years are subject to audit by the various tax authorities. In evaluating the tax benefits associated with our various tax filing positions, we record a tax benefit for uncertain tax positions using the highest cumulative tax benefit that is more likely than not to be realized. A number of years may elapse before a particular matter for which we have established a liability is audited and effectively settled. We adjust our liability for unrecognized tax benefits in the period in which we determine the issue is effectively settled with the tax authorities, the statute of limitations expires for the relevant taxing authority to examine the tax position, or when more information becomes available. We include our liability for unrecognized tax benefits, including accrued penalties and interest, in income taxes payable on our consolidated balance sheets and in income tax expense in our consolidated statements of operations. |
||||||||||||||||||||
| Comprehensive income (loss) | Comprehensive (loss) income: We follow the provisions of ASC 220, Reporting Comprehensive Income, which establishes standards for reporting and displaying comprehensive income and its components. Comprehensive (loss) income reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. For us, comprehensive (loss) income represents net income (loss) adjusted for foreign currency translation adjustments and unrealized gains and losses on available-for-sale securities. The foreign currency translation adjustment included in comprehensive (loss) income has not been tax affected, as the investments in foreign affiliates are deemed to be permanent. In accordance with ASC 220 and ASU 2011-05, we disclose comprehensive (loss) income on a separate consolidated statement of comprehensive income. |

| Shipping and handling cost | Shipping and handling costs: Shipping and handling costs collected from our customers in connection with our sales are recorded as revenue. We record shipping and handling costs as a component of cost of sales at the time the product is shipped. |

| Earnings per share (EPS) | Earnings per share (“EPS”): Basic EPS is computed by dividing income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution which may occur if securities or other obligations to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock which share in our earnings. |
||||||||||||||||||||
| Share-based compensation | Share-based compensation: We account for share-based compensation in accordance with ASC 718, Compensation-Stock Compensation. Under the fair value recognition provisions of ASC 718, we measure share-based compensation cost at the grant date based on the fair value of the award and recognize the compensation expense over the requisite service period, which is the vesting period. See Note 9 for additional information and the assumptions we use to calculate the fair value of share-based employee compensation. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. The ASU amends guidance for the presentation of comprehensive income. The amended guidance requires an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate but consecutive statements. The previous option to report other comprehensive income and its components in the statement of shareholders’ equity has been eliminated. Although the new guidance changes the presentation of comprehensive income, there are no changes to the components recognized in net income or other comprehensive income under existing guidance. In the first quarter of fiscal 2013, we revised our presentation of comprehensive income to conform to the guidance in this ASU. In September 2011, the FASB issued ASU 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment. Under this new standard, entities testing goodwill for impairment now have an option of performing a qualitative assessment before having to calculate the fair value of a reporting unit. If an entity determines, on the basis of qualitative factors, it is more-likely-than-not the fair value of the reporting unit is less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. This ASU is effective for impairment tests after April 29, 2012. The adoption of this standard did not have an impact on our consolidated results of operations or financial condition, as this ASU impacts only the analysis performed. In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The amended guidance gives entities the option to perform a qualitative impairment assessment to determine whether it is more-likely-than-not an indefinite-lived intangible asset is impaired. An entity must identify and evaluate changes in economic, industry and entity-specific events and circumstances affecting the significant inputs used to determine the fair value of an indefinite-lived intangible asset and whether it is more-likely-than-not the fair value exceeds its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this amended guidance is not expected to have an impact on our consolidated results of operations or financial condition, as the ASU impacts only the analysis to be performed. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef

The amount of the gain (loss) recognized by the parent and included in its attributable portion of net income for the period due to deconsolidation of a subsidiary or derecognition of a group of assets. The gain (loss) recognized and included in the net income attributable to the parent for the period is generally computed as the difference between: (a) the aggregate of: (1) the fair value of any consideration received; (2) the fair value of any retained noncontrolling investment in the former subsidiary at the date the subsidiary was deconsolidated; and (3) the carrying amount of any noncontrolling interest in the former subsidiary (including any accumulated other comprehensive income attributable to the noncontrolling interest) at the date the subsidiary was deconsolidated and (b) the carrying amount of the former subsidiary's assets and liabilities.
