为了更好地利用基于视觉暂留原理（POV原理）的旋转式线阵LED显示屏技术,采用Qtouch触摸技术与旋转LED屏相结合的方法,设计了一款基于TLC5947和ARM Cortex-M3核STM32F103的低成本、低功耗、高分辨率的LED屏显示控制器。实验结果表明,该旋转LED屏幕能够实现时钟、文字的显示功能,并能够在Qtouch触摸信号的控制下实现各种显示状态的切换工作。

In order to make better use of persistence of vision-based principles（POV principle） of the rotating linear array LED screen technology,the paper combines Qtouch control technology and rotary LED screen to design a low cost,low power consumption,high definition LED screen controller based on TLC5947 and ARM Cortex-M3 core STM32F103.The experiment shows that the rotary LED screen can achieve clock and words display function under the Qtouch touch signal,and the design can achieve all kinds of display status switch.
