Design and Implementation of Three Primary Color LED Display Screen
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 single-chip 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.
