文档介绍：基于Proteus的LED汉字显示屏电路设计
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。由于单片机技术的不断发展和高亮度LED发光管的出现使得大屏幕高亮度LED电子广告屏成为可能,与传统的霓虹灯广告在显示效果以及可修改性上都有着无法比拟的优势,而且单片机的日益平民化以及LED技术的不断创新,使得高亮度高清晰的LED点阵广告牌与传统霓虹灯广告牌的成本日益接近。为了能简单的实现基于单片机的LED显示系统控制,本文设计了基于AT89C51单片机16×16 LED汉字滚动显示屏电路并运用Proteus软件仿真实现其显示功能。本系统的设计具有体积小、硬件少、电路结构简单及容易实现等优点。

The Design Of Chinese Characters Display Circuit Based On Proteus LED
Abstract
As a new display device LED dot matrix display is consists of several independent LED light-emitting diode encapsulation. LED dot matrix display can display numbers or symbols, usually used to display time, speed, system status, etc. As the continuous development of puter technology and the display of high-brightness LED glowing tube, It makes the emergence of large-screen high-brightness LED electronic advertising screen to be possible, compared to the display effect and modifiability of The traditional neon advertising it has parable advantage and the growing SCM Civilian and innovative LED technology makes the brightness and high definition of LED dot matrix billboards and neon signs of the cost of traditional increasingly close. In order to achieve the 16×16 LED chinese scroll screen and using the Proteus software simulation shows the function. The design of the screen is small, less hardware, simple circuit structure and easy to implement.
