摘　　要：介绍了一种适用于FED平板显示器的灰度调制电路的设计。根据FED显示器的多级灰度显示原理,设计并实现了一种32通道、256级灰度调制电路。该电路具有POL输出极性控制、blank屏幕消隐控制等功能。详细阐述了8位计数器模块的设计思想和设计实现。最后,用MAX_PLUS II软件对主要模块进行了仿真验证,并给出了仿真结果。A 256 levels mission displays. It is POL and blank signals. gray-shade modulation circuit which has 32 channels is designed for field ecapable of 256 levels of POL. signal can invert th set all outputs to low. The design idea and achie module of this circuit is and the correct result is stated in detail. At last, given. gray shading by PWM conversion, and possesses e polarity of the output pulse, and blank signal can vement of the 8-bit counter, which is an important this module is verified by MAX_PLUS Ⅱ software
