Abstract

This paper introducuces the theory of large LED display screen based on 8031 chip microcomputer. When this driving circuit is designed, two column driving signal is used .The screen is divided in to two parts to scan.This improves the bright - ness and prevents flickering.The model of column is used for 74HC595 .When PC transmits data to the microcomputer with 8031 chip, the microcomputer with 8031 chip receives data and displays.The paper presents the block frame and the flow of software design.
