介绍一种新型彩色液晶显示系统。该系统以凌阳公司的嵌入式32位多媒体微处理器SPCE3200为主控制器，Sharp公司的LQ057Q3DC02彩色TFT LCD作为图像显示器。SPCE3200通过内置MPEG4/JPEG硬件编解码模块将Flash的图像数据解码后存入显示缓冲区内，LCD控制器产生驱动LCD所需的数据移位时钟、帧同步时钟与行同步时钟，并在时钟触发下将缓冲器内的图像数据传给LCD显示。给出彩色液晶显示系统的软硬件设计。
Abstract:
A new color LCD display system is introduced in this paper.The embedded 32-bit mulTImedia microprocessor SPCE3200 designed by Sunplus company is used as controller and LQ057Q3DC02 color TFT LCD designed by Sharp company is used for displayer by the system.Image data will be wrote into buffer from Flash after decoding by built-in MPEG4/JPEG hardware module.And then the data in the buffer will be transmitted into LCD with the help of data transfer clock,frame synchronizaTIon clock and line synchronous clock,which are produced by LCD.The hardware and software design are given.
