摘　　要：现代社会中,常见的LED显示屏大多都是采用固定的点阵排列,只能用于平面展示,易形成视觉疲劳。所以基于人眼的视觉停留(Persistence Of Vision)效应设计的旋转LED显示屏应运而生。本文设计一种新型的柱式旋转LED显示屏,使一排LED灯旋转起来变成一个圆柱面,来显示文字或者图案。本设计采用单片机,使一列LED灯快速旋转,在特定的位置上发光。这种显示方式新颖,画面绚丽多彩。In modem society, the common LED display is mostly used in fixed array, which can only be used for plane display. The traditional screen displays monotonously, which make visual organs tired. So LED＇s rotating display that use the persistence of vision of the human eye came into being. The design of a new column type of rotating LED display is proposed and it forms into a cylindrical surface by making a row of LED into rotation, thus it can display the text or a picture. This display based on SCM, using a series of LED lamps to rotate quickly, can show different words and pictures, and we must light different LED light in a specific location at every moment. The way it shows a picture or the text is unique and the image that it displays is bright and colorful.
