文档介绍：摘要
  LED显示屏作为一种新兴的显示媒体,随着大规模集成电路和计算机技术的高速发展,得到了飞速发展,它与传统的显示媒体相比较,以其亮度高、动态影像显示效果好、故障低、能耗少、使用寿命长、显示内容多样、显示方式丰富、性能价格比高等优势,作为新一代的显示媒体,已广泛应用于各行各业。特别是灰度显示屏以其现代化的姿态用于企事业单位形象宣传和公共场所信息显示,已成为无可替代的显示媒体。
本文采用单片机来控制整个LED点阵电路。需要显示的汉字较多时,直接将字库部分单独设置在整个电路的控制电路部分,掌握点阵汉字库的编码和从标准字库中提取汉字编码的方法。这样整个单片机系统的汉字编码就变得简单化。根据设计的总体要求,给出了该单片机点阵显示的硬件电路和软件程序,同时给出了单片机型号的选择、硬件设计、软件流程图。

Abstract
The LED display screen has been one kind of display medium new and developing , has been developed at full speed with the fact that the large-scale integrated circuit and puter art high speed develop,pares with the tradition display medium, the portrait demonstrates effect well, the malfunction is low, energy consumption is few, life time is elde, display content is various, the display way enriches, function price pared to advanced advantage with whose brightness height, development,be thenew generation display medium , apply to all professions and trades already broadly. Gradation demonstrates a screen especially being used to anxiously expect the institution image propagating sum a public place Visualization with the attitude that the person modernizes , already es the display medium having no but replacing.
The main body of a book is adopt to control the entire LED lattice ing monolithic machine. Need the Chinese character showing thecharacter warehouse part to be set paratively directly alone for a long time, in entire circuital control circuit part, method knowing lattice Chinese character warehouse code well and abstracting encode Chinese characters puters's from the standard in character warehouse. Such entire monolithic machine system encode Chinese characters puters esright away oversimplifying. According to the general requirement designingthat, have given the hardware owing a monolithic machine lattice display out circuit and the software program, choice , hardware design , software flow chart having given a monolithic machine out a type at the same time.
