LED点阵显示屏设计毕业论文.doc

摘要
随着21世纪科技的高速发展,现在我们的生活中无处不充满着令人惊奇震撼的新兴物品。而旋转LED显示屏,就是一款结合实用与娱乐的科技产品。随着LED的设计制造技术与应用水平的迅速提高,生活中无处不见LED。旋转LED显示屏,就是一款依托于LED技术,基于视觉暂留原理,开发出的旋转显示屏。显示屏不仅可以滚动字幕,更可以显示出静态图案和动态图案,还能显示模拟时钟和数码时钟两种状态。它以其色彩鲜艳,动态范围广,亮度高,寿命长,工作稳定可靠等优点是创意送礼求婚表白最佳选择,还可以作为装饰品摆放在咖啡厅、酒吧、家中等各种场所,是调节气氛的最佳选择。
由于LED显示屏具有良好的综合性能,因此自20实际80年代后期以来,得到了迅速的发展。从LED显示屏的发展过程开看,首先出现的是以显示短小文字信息为主的条形图文显示屏,继而开发出LED图像显示屏,他使得具有灰度级的图像能够在公共场合进行展示,成为当时一大景观。如今,更在LED显示屏上衍生出了本次论文的对象旋转LED显示屏。
本次论文对旋转LED显示屏的一些基本原理和各种驱动做了介绍,通过对显示模块和电源模块的分析,确定旋转LED显示屏的部件构件;通过对单片机及遥控模块的分析,确定旋转LED显示屏的组成结构和驱动方式,实现旋转LED显示屏的显示。

Abstract
With the social progress and development, people living on the increasingly high demand, the shopping desire more and more strong. Many businesses in order to attract customers eye, mostly with social the most cutting-edge technology to do publicity, LED display with its colorful, wide dynamic range, high brightness, long life, stable performance, energy-saving advantages, is a very good way of promotion, is a large entertainment, sporting events, Plaza decorating theme display information dissemination and other aspects of the important part in the LED screen, decorative display market will play a positive role.
As the LED display with good overall performance, so from the actual 20 since the late 80's has been rapid development. From the LED display to open the development process, the first is to show the short text message-based graphic display of the bar, and then developed a LED image display, he made with gray-scale image can be carried out in public places display, it was a great landscape. Full-color screen displays the status of the LED display to a new high, reaching unmatched by other types of display levels.
This article is a LED that is, some of the basic principles and introduced a variety of drivers, but also the development of the virtual pixel at this stage to do a brief analysis of advantages and disadvantages.
