A practical LED screen display circuit design
The big led display system has LED screen intuitive, content flexible, cost cheap and so on, so that was widely used in the public words and simple image information display. Because the pixel LED screen, to save hardware by dynamic scanning mode. Often To manufacture progre ive-scan as an example, suggest that process is commonly: (1) shows that it is a row in cache content into display lock to save; (2) light the bank and delay; (3) do vanish, and then pointer moves down a line and repeat the process. For small LED display system, this kind of method is feasible for the big screen, but for it with the increase of pixels, data transmission will take up a lot of time, the led display screen brightness declined obviously, especially for outdoor big led screen display system, and then using this method is unable to achieve the design will be practical effect. This paper introduces a new display control circuit can be an effective way to solve the problems.
