摘要: 研制一种利用人眼视觉暂留效应的线阵LED动态显示系统.该系统由电机带动一列LED高速旋转,通过单片机精确控制LED的亮灭时间,从而实现字符、图形及简单动态画面的显示.采用Visual Basic 6.0编写取模软件,将要显示的内容取模转换为数字信号,并将该信号用无线或有线方式传输给显示屏.系统由PC机端软件、移动控制器、显示屏3部分组成,能够实时变更显示内容及显示方式,可在360°范围内提供清晰的显示画面.

Abstract: Linear LED dynamic display system based on linetype array,which is the effect of persistence of vision,is manufactured.A list of 64 bits LED is rotated by the electromotor.Then the time of the LED’s lighting and extinguishing is controlled by the MCU.So the new style display screen is realized to show character,figure and simple motion screen.The software of the acquired module is compiled by the use of Visual Basic 6.0.The contents which should be displayed is transferred to digital signals.The...
