9.1: WITHDRAWN: 9.2: New Threshold Voltage Compensation Pixel Circuits in 13.5‐inch Quad Full High Definition OLED Display of Crystalline In‐Ga‐Zn‐Oxide FETs

Abstract

Abstract We devised a 5Tr+1C threshold voltage compensation pixel circuit that operates even with a normally‐on transistor. Variations in threshold voltage can be reduced to 25 to 30%. We fabricated a 13.5‐inch quad full high definition (QFHD) OLED display, which has a top‐emission structure using white tandem OLEDs with color filters.
