论述基于FPGA的FED视频驱动显示控制系统的工作原理,包括了视频采集控制模块、缓存模块、时钟控制模块、集成灰度调制控制模块以及行集成控制模块等的FPGA控制技术。研制出了FED显示器样机,能显示彩色视频图像。样机亮度已达200cd/m^2,对比度达600:1.显示分辨率为480×240,电路灰度等级达256级,有效显示对角线尺寸为25in。
Presented the principle of large screen field emission display integrated system based on FPGA control technology which includes the video sampling module, buffer module, clock control module, integrated gray-modulation control module and the integrated row control module. The system thus fabricated the large screen sample that could display color images. The sample obtained its screen brightness about 200cd/m^2, contrast ratio 600:1,480 × 240 resolution, 256 circuit gray scales and 25 inch display size.
