采用PWM和FRC混合算法实现256K彩色LCD驱动芯片的灰度调制

Algorithm of PWM and FRC Grayscale for 256 K Color LCD Driver

讨论了一种支持256 K彩色无源液晶显示驱动芯片中的灰度调制算法。该算法达到64级灰度,采用了PWM和FRC混合调制,并在硬件结构上进行了改进设计,可以减少硬件逻辑,降低频率要求。

This paper describes the algorithm which mixed PWM and FRC grayscale used in 256 K color LCD driver. This arithmetic implementation reduces hardware logic gates and frequency.
