HV632PG在彩色FED集成驱动系统中的应用

The application of HV632PG in color FED integrated driving system

论述集成场致发射显示系统的工作原理,包括HV632PG的性能以及作为列图像驱动器的接口电路、行集成驱动器STV7697芯片和FPGA控制技术等.采用HV632PG芯片研制出了彩色FED显示器样机,能显示彩色视频图像.样机亮度已达200cd/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25英寸(635mm).

Presented the principle of large screen field emission display integrated system which includes the performance and the gray - shade column driving IC interface circuit about HV632PG, and STV7697, the raw driving IC, as well as, FPGA control technology. The system thus fabricated the large screen sample that could display color images. The sample obtained its screen brightness about 200 cd/m^2 , contrast ratio 600：1, 480×240 resolution, 256 circuit gray scale and 25 inch display size.
