Abstract

A design method of a TFT-LCD digital display controller based on FPGA is introduced in this paper.The functions such as TFT-LCD sequence generator, image information processing, alternate control of the double display RAM can be realized on a FPGA chip. According to the actual task and function requirement,the system security and flexibility are improved through cutting the interface function of special display and control chip.This LCD controller is applied to a DCU successfully,and can solve the actual problem.
