摘　　要：在数字视频处理系统中,液晶显示器的扫描刷新都是基于一定的时序和控制方式进行的.由于视频记录和监视常用的输出类型是PAL制,因此帧存控制技术在图形显示方面的应用尤为重要.通过液晶显示器显示刷新速度,阐述了SRAM双帧切换工作方式,同时重点描述帧存控制技术在PAL制图形显示系统中的实现和应用.In the digital video processing system, the scanning refresh of LCD is based on a certain time sequence and control mode. The common output type for video recording and monitoring is PAL, so the application of frame control technology in graphic display is very important. On the one hand, this paper explains the working mode of SRAM two-frame switching through the requirement of refresh speed of LCD display. On the other hand, it focuses on the realization and application of the control system in the PAL graphics display system.

关 键 词：扫描刷新 帧存控制 双帧切换
