FED平板显示器灰度调制电路的设计
The design of a gray-shade modulation circuit for FED
【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。
【Abstract】 A 256 levels gray-shade modulation circuit which has 32 channels is designed for field emission displays.It is capable of 256 levels of gray shading by PWM conversion,and possesses POL and blank signals.POL signal can invert the polarity of the output pulse,and blank signal can set all outputs to low.The design idea and achievement of the 8-bit counter,which is an important module of this circuit is stated in detail.At last,this module is verified by MAX_PLUS II software and the correct result is given.
