摘要

进入新世纪，光电子产业得到社会广泛的重视，LED显示作为信息传播的一种重要手段，已广泛应用于室内外需要进行服务内容和服务宗旨宣传的公众场所。尤其在没有投影仪的地方，旋转LED的优越性体现得非常明显，在当今高度发达的经济市场上，富有创意、应用面广的、挪移方便、具有吸引力的信息传播系统显得十分的重要！二十一世纪是数字传播的时代，随着LED技术的应用和普及，数字LED显示屏的应用非常广泛。传统的LED显示屏以平面效果居多，旋转式LED环形显示屏的设计，是利用人眼视觉暂留效应，通过高速电机带动LED阵列旋转，形成360度环形显示画面，可站在任何角度观看，完全无观赏死角，给人们一种新的视觉体验。本设计基于AT89S52单片机，采用独立的LED，通过直流电机带动旋转，可形成立体效果，使其更加绚丽，更具有观赏性，可广泛应用于家居，企业和公共场所。针对传统LED显示屏视角单一、体积较大、需要的发光二极管数目较多等特点，利用电机带动LED显示阵列高速旋转实现环形显示，达到360全视角，在相同显示信息量上降低产品体积，减少对发光二极管的使用，设计一个可以经常方便变换内容、能够携带方便、信息容量大、价格低廉、结构简单的信息播放系统，即旋转LED显示屏。

Abstract

In the new century, the photoelectron industry wide attention by society, LED display as an importa nt means of information dissemination, has been widely used in indoor and outdoor services, content and se rvices needed publicity purposes in public places. In particular, there is no projector in place, rotating LED' s superiority reflected very clearly in today's highly developed economy markets, creative, application wide , the diversion of convenient, attractive information dissemination system is extremely important! The twen ty-first century is the era of digital communication, with the LED technology and the popularity of digital L ED display is widely used. Traditional LED display to effect mostly flat, circular rotating LED display desi gn is the use of temporary stay in the human visual effects, high-speed motor to drive the LED array rotatio n, the formation of 360-degree circular display can stand on any point of view, complete without viewing d ead, to give people a new visual experience. The design is based on AT89S52MCU, using separate LED, dr iven by DC motor rotation, can form three-dimensional effect, make it more colorful, more spectator, can b e widely used in homes, businesses and public places. View traditional LED display single, larger and large r number of required characteristics of light-emitting diode, LED display of motor driven circular array of h igh-speed rotation of the display, to 360 full view, in the same amount of information displayed on the lowe r product volume and reduce on the use of LEDs, the design can often facilitate the transformation of a cont ent, can be portable, high information content, low cost, simple structure, the information broadcast system, the rotating LED display.
