Abstract:
A pixel, an organic light emitting display using the pixel, and a driving method thereof may compensate for degradation of an organic light emitting diode. The pixel includes the organic light emitting diode and a drive transistor that supplies an electric current to the organic light emitting diode. A pixel circuit compensates a threshold voltage of the drive transistor. A compensator controls the voltage of the gate electrode of the drive transistor in order to compensate a degradation of the organic light emitting diode.
