Application of Liquid Crystal Display Module with Chinese Graphical Lattice Stock to Laser Warning Receiver

在激光告警接收机中,为了直观显示激光的波长和入射方向,需要研究信息的显示技术。研究了字符点阵液晶显示模块(LCM 12864ZK)在激光告警接收机中的应用,实现了2线串行接口方式与单片机89C 2051通信,完成全中文人机交互图形界面。设计了简单方便的接口,编写了灵活的操作指令,其模块化的设计思想为多显示模并行应用提供方便。研究成果已经运用到激光告警设备中,能够实现快速显示敌方激光的波长与方向等信息。

In order to display the wavelength and incident direction of laser intuitionisticly, it is necessary to research information display technology in laser warning receiver. The application of Character Lattice Liquid Crystal Display （LCD） Module （LCM12864ZK） in laser warning receiver is researched in this paper. The communication between two lines serial interface mode and MCU 89C2051 and mutual graphical interface in Chinese between people and computer are realized. The convenient interface and flexible operating instructions are designed. The modularized design strategy of the paper will be convenient for the parallel application of multi-LCD. The production has been applied in laser warning receiver successfully and has realized fast information display of the laser wavelength and direction of the rival.
