Organic light emitting display and driving method thereof

摘要

An organic light emitting display includes a display unit (130) includes pixels (140, 240) coupled to scan lines (S1, S2, S3, Sn), control lines (GC1, GC2, GC3, GCn), and data lines (D1, D2, Dm). A control line driver (160) for provides control signals to the respective pixels (140, 240) through the control lines (GC1, GC2, GC3, GCn) and a first power driver (170) applies a first power (ELVDD) to the pixels (140, 240) of the display unit (130) while a second power driver (180) applies a second power (ELVSS) to the pixels (140, 240) of the display unit (130). The first power (ELVDD) and/or the second power (ELVSS) is applied to the pixels (140, 240) of the display unit (130) having voltage values at different levels during periods of one frame, and the control signals and the first and second powers (ELVDD, ELVSS) are concurrently provided to all of the pixels (140, 240) during the emission period of a frame.
