摘　　要：针对液晶显示器用于便携式医疗仪器波形显示时的 RAM地址定位问题采用单片机设置地址扫描变换区 ,根据单片机采集数据的幅值通过查表的方法确定显示 RAM地址 ,从而确定出显示屏对应点的亮 /灭 。The problem of how to decide the video-RAM address when a liquid crystal display (LCD) is used in waveform display of small medical instruments is put forward. This paper recounts a method by building a address scanning change area in a microprocessor in single chip and using the sampling data to check the table of address change, so as to decide the address of video RAM and the bright/darkness of pots in screen to come true waveform display.

关 键 词：波形显示 液晶 地址扫描 医疗仪器 RAM地址定位问题
