摘要： 介绍了一种嵌入式LCD控制器的设计和实现方案。提出了实现对LCD控制器的两种设计方案构思,其中:一种方案采用一片CPLD和两片帧存的控制器设计方案;另一种只采用一片CPLD和一片帧存的控制器设计方案。分析了两种方案的优点和弊端,详细介绍了后一种方案,并给出了它的实现方法。该方案只要 稍作改动就能应用到其他的LCD上。

关键词: 视频时序控制器, 帧存控制器, CPLD

Abstract: The design of embedded liquid crystal display(LCD) controller is introduced and realized. Two proposals are brought forward, compared and analyzed, one of the two uses a CPLD that has more pins and two static random access memory (SRAM),the other uses a CPLD that has less pins and only one SRAM. Then it analyzes the advantage and disadvantage of the two proposals. The last one is introduced in detail. It can be easy applied to other type of LCD.
