摘　　要： 设计一种基于单片机的大屏幕LED显示屏控制系统,由单片机、串行通信电路、存储器电路、显示屏及行列驱动电路组成。广泛应用于商场、学校、银行、邮局、机场、车站、码头、金融证券市场、文化中心等公共场所进行广告、新闻和信息发布,可显示M行N列汉字、字符、数字和图片,可实现上下、左右移动等显示方式。采用模块化结构设计,扩展容易,操作方便、使用灵活。详细介绍了控制系统设计方法,并给出了系统仿真运行结果。经实际应用表明,稳定可靠,效果良好。 This paper designs MCU-based control system for large LED display screen, which consists of MCU, serial communication circuit, memory circuit, display screen, and the row and column driving circuit. They are widely used in shopping malls, schools, banks, post offices, airports, railway stations, docks, financial and securities markets, cultural centers and other public places for advertisement, news and information releasing, which can display the MX N Chinese characters, characters, numbers and pictures and realize the vertical and horizontal displaying mode. The system based on modular design is easy to expand, convenient to operate and flexible to use. This paper introduces the design scheme of control system, and gives the system simulation results. The practical application shows that the system has the characteristics of stability, reliability and good effects.
