Abstract: 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 grayscale depth .This paper also introduces its logic design and give its simulation pattern.
