Abstract

This paper proposed a micro-LED pixel circuit utilizing lowtemperature polycrystalline oxide (LTPO) technology. Unlike conventional designs, our approach leverages coupling effects to nullify threshold voltages in both segments without signal line augmentation. A more stable emission current is achieved through altered emission methods, yielding an error rate below 4%.
