摘要:
A pixel capable of compensating for deterioration of an organic light emitting diode includes an organic light emitting diode. A pixel circuit includes a first transistor controlling an amount of current supplied from a first power supply to the organic light emitting diode corresponding to a data signal. A compensating unit controls a voltage of a gate electrode of the first transistor to compensate for deterioration of the organic light emitting diode. The compensating unit includes a second transistor coupled between the gate electrode of the first transistor and the organic light emitting diode and turned off during a period of the supply of the data signal to the pixel circuit, and a feedback capacitor coupled between the second transistor and the organic light emitting diode.
