Design of Picture Display Experiment for LED Display Screen
Author(s): 
Pages: 56-58,134
Year: Issue:  3
Journal: Experiment Science and Technology

Keyword:  LED显示屏图片显示单片机驱动程序;
Abstract: 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,再根据运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.
