摘要

A data channel reuse solution was proposed for resolving correction parameters updating manually problem.Starting with general LED display system,the channel reuse idea was proposed and a mathematical model of the control strategy was established,which was utilized to guide strategy design and implementation.An online updating correction parameters was realized by reusing data channel in display system.Through theoretical analysis and experimental verification,the system can overcome the problems of the process of correcting parameters,such as the time consuming,damage of hardware.%针对全彩 LED显示屏校正参量更新过程中的问题，提出一种数据通道复用的系统解决方案。首先以通用 LED显示系统为基础提出借助数据通道进行校正参量更新传输的设计思想，然后在理论上建立控制策略与校正参量的数学关系模型，并依此指导控制策略的设计和实施，最后对显示控制系统进行硬件资源的复用设计，实现校正参量的在线更新。通过理论分析和实验验证，在不增加硬件资源以及传输通道的前提下，该系统解决方案可以简单有效解决校正参量更新过程。
