Abstract

Picture display experiment of light emitting diode(LED) display screen is introduced in this paper.The paper analyzes the display principle of LED display screen,as well as the timing relationships between each drive signal.With a display image,word-model extraction software is utilized to extract image display date firstly,then according to the principle of dynamic display,we send the image data to LED display screen according to certain order.The students can master the operating principle of LED display screen and improve the ability to design the driving program through the experiment.This experiment integrates theory with practice and has achieved good teaching effect.
