旋转LED显示屏设计

Design of Rotating LED Display

LED显示屏作为信息显示媒体,具有可靠性高,性价比高,节能效果好等优点,在平面显示领域得到了广泛的应用。本文设计了基于单片机的旋转LED显示屏,利用视觉暂留现象,实现基于旋转LED线阵的图像显示。通过介绍旋转LED显示屏成像原理,阐述了系统总体结构,设计了系统供电电源部分、时钟部分、LED显示屏驱动部分及红外遥控部分等硬件电路,在硬件电路的基础上,编写了软件程序,软硬件联合调试下,成功实现旋转LED显示屏的文字、图片、动画信息的显示。

As an information display media,LED display has been widely used in the field of plane display for the advantages of high reliability,high cost performance and good energy saving effect.In this paper,a rotating LED display is designed based on single chip microcomputer.Image display is realized by using persistence of vision.Hardware circuits of power supply,clock,LED display and remote control part are designed.Based on the hardware circuit,the software program is compiled.Under the debugging of software and hardware,the display of text,picture and animation information is successfully realized.
