摘　　要：为改善图像质量,提出了一种基于脉冲分散算法的高动态刷新率三色48bit辉级深度的扫描控制方法,并介绍了基于此方法的LED辉级控制的逻辑设计,使LED屏具有高动态刷新率和深度的γ校正,从而显著提高显示质量。In order to improve the image quality, a new display-scanning controlling method is proposed based on dispersed pulse algorithm. The method can provide high-dynamic refresh frequency and 48 bit γ-correction of tricolor. Furthermore, the logic design idea of the controller is introduced. And thus, the LED display is ensured to have high depth of brightness and high refresh frequency, and the display quality is improved remarkably.
