摘 要: 介绍了一种环场 L ED多色显示屏技术。该显示屏的主要原理是基于人眼的视觉暂留功能。电机带动 L ED像素列旋转 ,同时由单片机分时向像素列发送控制信号 ,并通过适当的延时 ,形成环场显示。 A technique of cylindrical LED multicolor display is developed. The display is based on the persistence of vision. The cylindrical display mainly consists of electromotor,microchip and LED pixel lines,which are made rotating by a electromotor and receive control and delay signals from microchip.
