Abstract
For the shortcomings in refresh rate of the traditional LED display,a PWM control circuit to improve the refresh rate of the LED driver is designed. A refresh cycle average scattering is divided into 128 sections,each con⁃taining 256 gray clocks,and the duty ratio of PWM is determined by the 16 gray scale data. At the same time,by us⁃ing gray counters with double edge triggered,refresh rate of LED display is increased and avoids flicker.关键词
