为了满足更多用户需求,实现显示屏使用的简单化,设计了一套由控制器、单元板及上位机显示管理系统组成的异步LED显示控制系统。系统中下位机采用以STC89C52RC单片机为处理器的控制器,对LED显示屏的显示方式、亮度和时间等进行控制;屏体采用单元板拼接的方式构成,单元板由3.75双色点阵显示模块及行列驱动器件构成,大小为64×32点;上位机显示管理系统可实现显示数据、显示方式和内容等。通过实际的安装与测试表明,该系统具有较高的可靠性和稳定性,在显示方式上可以实现左移、上移和翻屏等多种显示方式。
In order to meet the needs of more users and simplify the use of the display, a set of asynchronous LED display control system composed of a controller, a cell board and a host computer display management system is designed. The lower computer in the system adopts STC89C52RC microcontroller as the controller of the processor to control the display mode, brightness and time of the LED display screen. The screen body is formed by the splicing of the cell plate, and the cell plate is composed of a 3.75 two-color dot matrix display module and The ranks of drive components, the size of 64 × 32 points; PC display management system can display data, display and content. Through the actual installation and testing shows that the system has high reliability and stability, in the display mode can be achieved on the left, up and flip and other display.
