数据寄存式LED显示屏控制器

Data register LED display screen controller

数据寄存式ＬＥＤ显示屏控制器的主要设计思想是设法延长ＬＥＤ的点亮时间，达到提高显示屏亮度的目的。主要设计原理是在屏幕与控制器之间加一个寄存器，该寄存器的每一位对应ＬＥＤ屏上的１个发光器件，且可动态刷新，从而达到预定的控制目的。

In order to increase brightness of the data register LED display screen, the main design thoughts are trying to delay light time to every LED. It was the main design principle to put a register between screen and controller. Every bit of the register corresponds to one shining device and brushing every bit all time,thus, the brightness of the screen was increased.
