介绍了一种基于ARM9的彩色薄膜晶体管液晶显示模块(TFT—LCD)的设计和实现方法。为了解决图像及字符在液晶模块上的实时显示，图像库及字符库存储在容量达64 Mbyte的NAND Flash闪存中，可以根据不同需求对图像库及字符库进行更新。模块支持24 bit彩色RGB格式图像的显示，还支持JPEG格式图像的显示，JPEG图像的解码功能在ARM9处理器上实现。模块采用串口方式与其他外接主控系统通信，-Introduces ARM9-based thin-film transistor color liquid crystal display module (TFT-LCD) design and implementation. In order to solve the image and character in real-time display on the LCD module, image database and character database is stored in the capacity of 64 Mbyte of NAND Flash memory, you can image database according to different needs and character of the library to be updated. Module supports 24 bit RGB format color image display, also supports the JPEG format image display, JPEG image decoding implemented on the ARM9 processor. Modules use serial mode communication with other external main control system,
