P‐13.10: AMOLED IR‐drop Automatic Compensation Based on Real ELVDD

Abstract

This paper introduces a scheme to compensate IR drop in real time based on the real ELVDD in display. The real ELVDD of each row of pixels at the time of charge and discharge is obtained by designing detection circuits on both sides of the display, and the pixel voltage Vdata is adjusted by the detection voltage. In this way, the display problem caused by local and global IR drop can be solved in a direct and effective way.
