DRIVING CIRCUIT FOR DUAL ORGANIC LIGHT EMITTING DIODES, AND DUAL-PIXEL CIRCUIT INCORPORATING THE SAME

Abstract

A dual-pixel circuit includes first and second OLEDs, and a driving circuit that includes first and second driving transistors, a capacitor, and a switching module operable between first and second modes based on a data voltage, first and second scan voltages, and first and second bias signals. When the switching module is operated in the first mode, the first OLED is forward-biased to emit light, and the second OLED is reverse-biased. When the switching module is operated in the second mode, the first OLED is reverse-biased, and the second OLED is forward-biased to emit light.
