摘　　要：论述集成场致发射显示系统的工作原理,主要包括了数字视频图像的转换和处理、视频数据的传输、列灰度驱动集成HV632PG和行集成驱动器STV7697芯片的接口电路以及FPGA控制技术等。采用集成FED驱动系统研制出了彩色FED显示器样机,首次用于大屏幕低逸出功型印刷式场致发射显示器,能显示彩色视频图像。FED驱动电路的集成化大大地降低电路结构的复杂性,使整个驱动电路的稳定性提高,厚度变薄、重量减轻。样机亮度已达200 cd/m2、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63.5 cm(25 in)。The principle of field emission display integrated system was presented, which includes the transform and processing of digital video image and the transmission of video data, the interface circuit about HV632PG, the gray-shade column driving IC, and STV7697, the raw driving IC, as well as, FPGA control technology. Using this system, colour FED model was fabricated and used in the large screen low work function printing FED that could display color images for the first time. The integration of the system strongly reduced the complexity of the circuit, improved the stability of the system, made it thinner and lighter. The sample obtained its screen brightness about 200 cd/m^2 , contrast ratio 600：1, resolution 480×240, 256 circuit gray scales and 63.5cm（25 in） display size.
