摘　　要：针对CRT显示器的缺点提出了对显示部件进行改进设计方案,采用当前在军事领域大量使用的LCD平板显示器和计算机控制技术,利用程控译码器和视频显示器的接口信号,实现显示目的并提高显示效果。在改进方案中采用了A/D转换技术、中断等技术,利用控制信号产生中断进行模拟信号的采集和数字信号的提取,译码后在LCD显示器上复现出来。改进后的显示器除能完成所有CRT显示器的功能外还具有自校准功能,且可以显示中文参数表页,使操作更加简便。The paper introduces a display system＇s improvement design project aiming at disadvantages of CRT display. In the design project, it adopt the LCD fiat panel display which is used widely in the military realm as the displaying part, and it adopts the computer technique such as program control encoder and video display＇s interface signal. The design could attain the display purpose and improve display quality. In the improvement design project, it also adopt A/D and interrupt technique which could produce interruptedly gathered simulative and digital signal which could re-display in the LCD after coding. The improved display not only has CRT＇s all function but also has self-checkout function. It could show Chinese character which could help manipulator and commander to read.
