In this paper, the color coordinate influence factor is disassembled as device characteristics and process, by comparing the color coordinate distribution data before and after brightness compensation for a 9.38-inch 480x960 resolution MicroLED display with the PAM driving mode and the emitting mode of 4 pulses 20% duty cycle.
