Abstract:
1. An organic light emitting display comprising: a display unit comprising a plurality of pixels arranged in a plurality of rows and columns coupled to scan lines, control lines, and data lines, wherein each of the pixels comprises an organic light emitting diode; a control line driver for providing control signals to the pixels through the control lines; and a power driver for applying a power, at different levels, to the pixels during a plurality of periods of one frame, wherein the power comprises a first power applied to the pixels, wherein each of the control signals is concurrently provided with each of the other control signals, at a turn-on level, directly to a switch electrically coupled between the first power and the organic light emitting diode in a corresponding one of the pixels, wherein the power is concurrently provided to each of the pixels, wherein the plurality of periods of one frame comprises a reset period, a threshold voltage sensing period, a scan period, an emission period, and an emission turn-off period, wherein the first power is applied at a low level during the reset period and the emission turn-off period, wherein the first power is applied at a high level during the threshold voltage sensing period and the emission period, and wherein the first power is applied at a level lower than the high level and higher than the low level during the scan period.
