Abstract :
This article introduces a video LED display system that uses a new way for grayscale driving and can provide better visual effect. The consecutive PWM driving used in the new display system is able to incorporate the grayscale characteristics with high precision and display images with 64 to 256-grayscale, which are difficult or even impossible to realize by the discrete PWM driving LED displays
