一种新型线阵LED图文显示装置的研制
A New Design of Linear Array LED Display Device
摘要
基于视觉暂留原理, 提出一种新的线阵LED图文显示装置;将16个LED灯固定在一个木板上, 均匀排列在一条直线上, 驱动直流电机带动木板旋转, 当转速提高到一定的值时, 16个LED灯可形成一个稳定的圆平面, 通过程序控制面板上16个LED灯的亮灭时间, 可在圆平面上显示出不同的文字或图形;在设计中给出了硬件电路设计和软件流程, 并根据视觉暂留原理给出了显示算法;实验结果证明: 该方法可稳定的显示不同的字符和文字, 且无明显的漂移。
Abstract
A new construction of linear array LED display device is proposed based on the principle of persistence vision. Sixteen led have been fixed in a board, which is evenly array in a straight line, driven DC motor rotating the board, when the speed reached a certain value and stability, through programming to control sixteen LED display on or off time, different text or graphics can be seen on the screen. In the design hardware circuit and software flow chart are given, according to the principle of persistence vision the display algorithm is given. The test result show that the device can display different character and text and can display stable.
