The control system included the following units : video decode unit, data format conversion unit, fpga controller, cache unit and d / a monitor. the above self - design control unit plus row and column power supply units make the whole fed driving system, thus drove the 25 inch sample and realized color video display. the 25 inch vga sample thus fabricated could display video images, and obtained its brightness 400cd / m2, contrast ratio 1000 : 1, 256 circuit gray scale
本文介紹了fed驅動系統的工作原理，重點論述了基於fpga的vga級彩色fed新型驅動控制系統的研製，這種新型fed驅動控制系統主要包括視頻解碼電路、數據格式轉換電路、 fpga控制電路、數據緩存電路和d / a監控電路，配合后級列灰度調制單元和行掃描單元，組成完整的fed驅動系統，可以驅動25英寸vga級fed顯示屏，實現彩色視頻顯示，樣機亮度達400cd / m2 、對比度為1000 : 1 ，灰度等級為256級。 -
For the anticounterfeiting of printings ( such as certificate ), the existent many ways ( such as rainbow holograms ) are not available as the need for special use : anti - distortion and anti - copy. basing in the double - random - phase transform, this article puts forward a new way that two - dimensional bar code is used as anticounterfeiting label with anti - printing ? scanning and anti - damage properties. the major job are : ( 1 ). basing in the ascii codes, numerals and alphabets are encoded and subsequently transformed into two - value bar code matrix figure. later, using amplitude - based double - random - phase transform, the enciphered gray scale figure is formed. by computer simulation ( 4f system ) and printing as well as scanning ( 20 times ), we get the result that the gray scale figure with little miscoding rate ( 0. 0026 ) by “ matrix expanding way ”
本文主要開展了以下三項研究工作: （ 1 ） .用自定義編碼方案，將數字和字母（ ascii碼）轉換成二值條碼圖;對該圖形進行振幅型雙隨機相位加密變換，得到原信息的加密灰度圖;通過4f光學系統計算機模擬和列印-掃描實驗，證明本文提出的「矩陣擴展法」灰度圖具有較小的誤碼率，對於20次列印-掃描實驗，誤碼率不大於0 . 0026 。 -
Finally, the anti - jamming system is discussed. through simulation analysis and experiment on signal integrity, the method of improving stability of the circuit is presented. circuit testing proves that the “ sub - row ” gray - scale modulating method is suitable for our printable fed with low work. the designed circuit has been applied to our fed sample which can display vga format video with 256 gray - scale and brightness of 400 cd / m2
實際電路測試證明，子行灰度調制的方法適用於印刷型低逸出功fed顯示屏，所設計的灰度調制驅動電路已成功應用於25英寸彩色fed樣機中，可顯示vga格式視頻圖像，灰度等級為256級，顯示亮度達400cd / m2 。 -
