基于WINCE5.0的差分接口LCD驱动的实现

The Implementation of the Differential Signal LCD Driver Based on WINCE 5.0

该文以S3C2440A为核心,以友达G065VN01 V2型号的差分信号接口TFT_LCD为例,阐述了LCD控制器的工作原理,实现了从控制器的CMOS/TTL信号到LCD接口LVDS(低压差分信号)的转换;同时介绍了在嵌入式操作系统WINCE 5.0下LCD驱动程序的结构模型,以及如何在S3C2440A平台上实现LCD驱动移植。

This paper takes S3C2440A as the core, uses AUO G065VN01V2 differential signal interface TFT _LCD as an example, elaborates the base functions of the LCD controller, realizes the conversion from the controller CMOS/TTL signal to the LCD interface low voltage differential signal（LVDS） ; at the same time it introduces the structure of LCD driver in WINCE5.0 and how to migrate the LCD driver based on S3C2440A platform.
