基于USB和OLED的分布式多屏电子公告系统设计

Design of distributed and multi-display electronic bulletin system based on USB and OLED

OLED作为新一代显示技术,广泛用于各种高端产品的显示终端,实时显示字符、汉字、曲线等信息。以OLED显示屏应用为研究对象,设计开发一种基于USB接口传输的分布式多屏同步显示的电子广告屏控制系统,给出OLED的行列驱动电路以及USB接口器件和单片机的接口电路,并介绍软件开发方法,给出以中断方式进行数据传输的部分实用程序。

As a new generation display technology, OLED is used widely in a variety of display terminals of high-end prod- ucts, real-time displays characters, chinese characters,curves and other information.In this paper,the application of OLED display screen is the research object, the electronic advertisement screen control system of the distributed and multi-dis- play synchronized display is designed based on USB interface transfer,the ranks driver circuit of OLED,the interface cir- cuit of USB chip and the MCU is given ,and the method of software development is introduced and the partical program of data transmission by the mode of interruption is given.
