摘 要 LED电子显示屏是随着计算机及相关的微电子、光电子技术的迅猛发展而形成的一种新型信息显示媒体。它利用发光二极管构成的点阵模块或像素单元组成可变面积和显示屏幕，以可靠性、使用寿命长、环境适应能力强、性格价格比高特点，在短短的十来年中，迅速成长为平板显示的主流产品。由于LED电子显示屏具有显示内容信息量大，外形美观大方，操作使用方便灵活，用户可随时任意自行编辑改显示内容，显示方式图文并茂等优点，因此被广泛应用于商场、学校、银行、邮局、机场、车站、码头、金融证券市场、文化中心、信息中心休息设施等公共场所。 关键词：LED电子显示屏，发光二极管，E2PROM2864，555定时器 Abstract The LED electron display monitor is one kind of new information demonstration media which along with the computer and the related micro electron, optoelectronic technology's rapid development forms. It uses the lattice module which or the picture element unit composition variable area and the screen the light emitter diode constitutes, by the reliability, the service life is long, environment adaptiveness is strong, the disposition price scaled height of burst characteristic, in the short ten years, grows rapidly into the panel display mainstream product. Because the LED electron display monitor has the demonstration content information content to be big, the contour elegant appearance, the operation easy to operate is flexible, the user may momentarily willfully voluntarily edit changes the demonstration content abundantly and elegantly, the display mode and so on merits, therefore is widely applied in the market, the school, the bank, the post office, the airport, the station, the wharf, the finance stock market, the cultural center, the message center rest facility and so on public place. Key words：The LED electron display monitor,Light emitter diode，E2PROM2864，555Timer 可编程动态广告牌控制系统设计相关范文 |
