摘要

全彩LED显示屏的性能与刷新率密切相关，本文提出了一种基于分散脉宽调制的先进扫描方式，并给出了将一个脉宽调制脉冲分解成多个规则窄脉冲的算法。这种扫描方式可以提供比固定频率更高的动态刷新率，即使在低帧频下也能消除闪烁效应，扩大灰度深度。本文还介绍了其逻辑设计并给出了仿真图。

Algorithm of Dispersed PWM and Dynamic Refresh Mode for LED Display

The performance of full-color LED display is related with refresh rate, This paper presents a advanced scan mode based on dispersed PWM, and illustrates the algorithm to disassemble a PWM pulse into many regular narrow pulses. This scan mode can provide very high dynamic refresh rate rather than fixed frequency, eliminate flicker effect even as low frame frequency and expand gray-scale depth .This paper also introduces its logic design and give its simulation pattern.
