1、 毕业设计说明书 基于基于 Proteus 的的 LED 汉字汉字显示显示屏电路设计屏电路设计 院（系）名称 信息工程学院 专业名称 电子信息工程 2011 年 5 月 15 日 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

2、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。 关键词：关键词：LED，单片机，Proteus 仿真 The Design Of Chinese Characters Display Circuit Based On Proteus LED Abstract As a new display dev

3、ice 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 microcomputer technology and the display of high-brig

4、htness 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 incomparable 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
