We added a distributed PWM (D-PWM) to the original switch structure of a traditional IC to intersperse low grayscale data (D[2]) in high grayscale data (>D[2]). Following figure shows D[2] interspersed in D[5] and D[4]. 

High grayscale and low grayscale data are dispersed as Bit3 and Bit0. Data transmission and channel opening sequences are arranged logically to realize high refresh rate, high grayscale, and high utilization rate.
