LED显示屏的图片显示实验设计

Design of Picture Display Experiment for LED Display Screen

该文就LED显示屏的图片显示实验进行了探讨。分析了LED显示屏的显示原理,以及各个驱动信号之间的时序关系。在显示图片时,先利用字模提取软件提取图片的显示数据,再根据逐行扫描的动态显示原理,将显示数据按照一定的先后顺序送到LED显示屏显示。通过实验可使学生掌握LED显示屏的工作原理,提高驱动程序设计能力。同时将理论知识的学习和实践环节有机结合,取得了良好的教学效果。

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 a- chieved good teaching effect.
