三基色LED显示屏的设计与实现

Design and Implementation of Three Primary Color LED Display Screen

LED显示屏因其低成本、高亮度、易维护等优势,逐渐成为主流的大型显示设备。文章描述了运用单片机H8/3048和FPGA芯片EPF10K10TC144-4作为主控制器件的LED显示屏设计方案,该方案运用单片机进行算法控制产生显示的数据信号和同步的控制信号。同时,运用FPGA搭建逻辑功能模块,用于接收信号,存储信号,将信号从串行输入变换成并行输出,再将信号传递给三极管功率驱动器件和LED显示屏,从而生成可静止、可上下左右移动显示的性能稳定的绿色、红色和橙色的三基色LED显示屏。

LED display screens have gradually become mainstream large-scale display devices due to their advantages of low cost,high brightness,and easy maintenance.This paper describes a design scheme for an LED display screen using singlechip microcomputer H8/3048 and FPGA chip EPF10K10TC144-4 as the main control devices.The scheme uses a single-chip microcomputer for algorithm control to generate displayed data signals and synchronous control signals.At the same time,FPGA is used to build logic function modules for receiving signals,storing signals,converting signals from serial input to parallel output,and then transmitting the signals to triode power driving devices and LED display screens,thereby generating green,red,and orange three primary color LED display screens with stable performance that can be stationary and move vertically and horizontally.
