ABSTRACT:
A pixel, an organic light emitting display, and a method for driving an organic light emitting display using the pixel, which can display an image with substantially uniform luminance. In one embodiment, the method for driving an organic light emitting display having a pixel disposed at an i-th horizontal line, the pixel having a drive transistor for enabling the flow of current to an organic light emitting diode, the method including providing a reference voltage to a gate electrode of the drive transistor, charging a second capacitor with a threshold voltage of the drive transistor, charging a first capacitor with a voltage corresponding to a data signal, and providing a current corresponding to the voltages in the first and second capacitors to the organic light emitting diode.
