16×16点阵LED电子显示屏的设计

摘要

LED点阵显示屏作为一种新兴的显示器件,是由多个独立的LED发光二

极管封装而成. LED点阵显示屏可以显示数字或符号, 通常用来显示时间、

速度、系统状态等。

本设计是16×

16

×16点阵LED电子显示屏的设计。整机以美国ATMEL公司

生产的40脚单片机AT89C51为核心，介绍了以它为控制系统的LED点阵电

子显示屏的动态设计和开发过程。通过该芯片控制一个行驱动器74LS154

和两个列驱动器74L373来驱动显示屏显示。该电子显示屏可以显示各种文

字或单色图像，采用4块8 x 8点阵LED显示模块来组成一个16x16点阵显

示模式。显示采用动态显示，使得图形或文字能够实现静止、移入移出等

多种显示方式。文中详细介绍了LED点阵显示的硬件设计思路、硬件电路

各个部分的功能及原理、相应软件的程序设计，以及使用说明等。

Abstract

As a popular display device component, LED dot-matrix display

board consists of several independent LED (Light Emitting Diode).

The LED dot-matrix display board can display the number or sign,

and it is usually used to show time, speed, the state of system

etc.

This design is 1 16 ×16 lattice LED electron display monitor

whole equipment is with the 40-pin AT89C51 MCU (Micro

Controller Unit) produced by the American ATMEL company at the

core, introduced take it as the control system LED lattice electron

display monitor dynamic design and the development process.

Controls good driver 74LS154 an two row driver 74L373 through this

chip actuates the display monitor demonstration. The electronic

screen can show all kinds of written or monochrome images, one full

screen display Chinese characters, four pieces of 8 x 8 dot-matrix LED

display modules to form the 16x16 dot matrix display mode. Show

dynamic show that makes static graphic or text can be achieved,

shifted out of various formats. This paper describes the

of the LED

dot matrix display, and the principle function of the various parts of
