Share Repurchase Program [Abstract]
Treasury Stock [Text Block]	Note 3. Share Repurchase Program On June 17, 2016, our Board of Directors approved a stock repurchase program under which Daktronics, Inc. may purchase up to $40,000 of its outstanding shares of common stock. Under this program, we may repurchase shares from time to time in open market transactions and in privately negotiated transactions based on business, market, applicable legal requirements and other considerations. The repurchase program does not require the repurchase of a specific number of shares and may be terminated at any time. During the first quarter of fiscal 2017, we repurchased 284 shares of common stock at a total cost of $1,825, and there have been no other purchases during the second quarter of fiscal 2017. We may repurchase up to an additional $38,175 of common stock under the current Board authorization.
