Demura, a technology that adjusts pixel brightness to improve the mura effect of a display, has been widely employed in AMOLEDs. We perform Demura verification on a 7.56-inch 240x320 resolution MicroLED with PAM driving mode in this study, and we examine the compensation distortion issue that exists during the process.
