摘　　要：许多设备和仪器往往要同时在１个屏幕上显示大量的复杂数据，如图形、曲线、汉字和功能符号，这是基于ＬＥＤ的显示技术所难以做到的。文章结合电力负荷控制终端的研制，以ＤＭＦ系列点阵式液晶显示器为例，对液晶显示器的工作原理、与单片机的接口电路。It is,sometimes,required to display complex data,such as figures,curves,chinese characters,and functional symbols etc,on a single screen of equipment and instrument at the same time.But this is difficult to realize based on LCD display technology.In conjunction with the development of load control terminal,with series DMF dot array LCD as an example,this paper describes the work principle of LED display ,the interface with single chip computer,and the driving program of C language in detail.
