摘　　要：LCD日益广泛应用于嵌入式系统实现人机交互。本文介绍了LCD显示与帧缓冲的基本原理，给出了每像素16比特模式下帧缓冲的组织形式，设计了ARM微处理器PXA270与TFT型LCD液晶屏LQ64D343的硬件接口，阐述了LCD控制器的操作流程和寄存器初始化方法，分析了帧描述符的操作方法，实现了中文字符和图片的显示。The LCD is applied widely in the embedded system. It is used to realize the Man-computer interaction systems. This paper introduces the basic operational principle of LCD display system and the frame buffer. It presents the frame buffer organization in 16bpp mode and the design of hardware interface based on PAX270 and LQ64D343. It also introduces the LCDC operation procedure, register initialization,frame buffer operation and display of Chinese and picture.
