基于ARM的真彩LCD驱动程序设计

Based on ARM's True Color LCD Driver Design

该文首先研究了SAMSUNG S3C2440 ARM芯片的LCD控制模块及液晶屏的接口,然后研究了NEC NL2432 3.5寸LCD真彩液晶屏的逻辑及成像原理。在此基础上,基于LINUX操作系统,对LCD驱动程序进行研究和实验,实验结果表明:本文研究出的LCD驱动程序适应性好,能够适应上述硬件芯片环境;系统稳定性好,能够得到清晰稳定的真彩画面。

First of all,we've done some research on the LCD controller of SAMSUNG S3C2440 and the interface of clearvision.Then we've discussed the logical and imaging principle of 3.5 inch color screen.With this background,we’ve done some experiment of LCD driver in LINUX operation system.The experiment results indicate that the diver is fit for the device above;and the driver is stable,some clear and stable pictures could be shown on the screen.
