1、云南广播电视大学云南国防工业职业技术学院电子工程学院毕业论文（设计）课题基于51单片机的LED立方体显示器教研室机械电子工程学院教研室专业电气自动化技术2012年10月10日摘要随着科技的不断发展LED(LightingEmittingDiode）,发光二极管)技术在10多年间取得了长足的进步，1990年前LDE以红绿双基色为主运用住处很少而且制造成本高昂。1990-1995年，这一阶段是LED显示屏迅速发展的时期。先后研制出蓝色LED、全彩色LED，LED屏的显示技术取得很大的提升。而今高亮度的三基色LED电子显示屏作为一种高科技产品日益引起人们的重视。它可以实时显示或循环播放文

2、字、图形和图像信息，具有显示方式丰富、色彩鲜艳、显示内容修改方便、亮度高、显示稳定且寿命长等多种优点，被广泛应用于商业广告、体育比赛、交通信息报导等诸多领域。在上海世博会开幕式上，竖立在黄浦江边的9500平方米的巨型LED显示屏价值高达人民币1亿元，是特别为上海世博会定制的。“它不仅超大，且非常轻和通透。”此外，这块屏幕还能抗震和防火。这块屏幕其实是迄今为止世界上面积最大的LED显示屏，它代表着LED屏发展的技术方向。现在LED在实际的运用中有了很宽广的范围，而且越来越收到人们的重视。在举世瞩目的北京奥运会上，在开幕式上出现了一个新名词“光立方”它是北京奥运会开幕式的亮点。本文所要

3、介绍的LED的另一种应用也叫光立方，运用高亮的LED显示出不同的3D图案、动画和文字，运用51单片机进行控制长、宽、高由8×8×8个LED灯组成的真实3D立方体显示器。其最大的特点，就是带给你未来3D技术的科技体验，在夜晚有让人震撼的3D效果给人眼前一亮的感觉。该光立方在显示3D图片和动画时从立方体的各各面都可以看到立体动画，富有科技感，让人觉得就像是在看3D电影一般而且还是不用3D眼镜的裸眼3D全方位不受视角限制的3D。相信这种富有科技感和实用性的LED显示技术在未来会是一大亮点。【关键词】LED；单片机；3D；51单片机目录第一章绪论······················
