1. An organic light emitting display comprising:
a display unit comprising a plurality of pixels 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 and a second power applied to the pixels, wherein the control signals at a turn-on level are concurrently provided to respective switches electrically coupled between the second power and organic light emitting diodes of the pixels, wherein the power is simultaneously provided to each of the pixels, wherein the plurality of periods of one frame comprise a reset period, a threshold voltage sensing period, a scan period, an emission period, and an emission turn-off period, wherein the second power is applied at a high level during the reset period and the emission turn-off period, and wherein the second power is applied at a low level during the threshold voltage sensing period and the emission period. |
