摘要
在研究和分析现有各种LED显示屏控制系统及标准LED单元板的基础上,提出了一种利用LED显示屏单元板排列方式驱动超长LED显示屏的新方法,可最大限度地保证超长LED显示屏显示数据的双向高速输出。在LED显示屏单元板移位时钟给定的情况下,可使超长LED显示屏在水平方向的长度提高1倍。
A new scheme of driving super-long LED panel with the array mode of LED cell board is proposed based on the study and analysis to all kinds of LED screen control system and the cell board. Relevant experiments and tests show that control system with this new method could maximize the speed of bidirectional data output to super-long LED panel. And the controllable horizontal length of LED large-screen could be doubled.
