| 摘 要： | 在LED全彩大屏幕显示中,为了增强灰度均匀性,降低闪烁感,通常采用脉冲打散的PWM驱动方式。然而这往往会使系统的工作频率成倍提高。本文提出了一种脉冲打散的新算法,能够在保证较低工作频率的同时提高脉冲打散的均匀性,增强灰度表现力。

| Abstract: | In the LED full-color display, in order to enhance the uniformity of the gray and reduce flickers, people commonly use the PWM which is scrambled. However, it will double their working frequency. This paper suggests a new pulse scatter algorithm, to improve the uniformity of the gray at a low working frequency. |
