Patent ID: 8319713

Claim:
A pixel comprising: an organic light emitting diode; a pixel circuit coupled to the organic light emitting diode, the pixel circuit having a first transistor for controlling current supplied from a first power supply to the organic light emitting diode corresponding to a data signal; and a compensating unit, coupled to the pixel circuit and the organic light emitting diode, for controlling a voltage of a gate electrode of the first transistor to compensate for deterioration of the organic light emitting diode, wherein the compensating unit comprises: a second transistor, coupled between the gate electrode of the first transistor and the organic light emitting diode and comprising a gate electrode, a first electrode, and a second electrode, for being turned off during a period of a supply of the data signal to the pixel circuit, and a feedback capacitor comprising a first electrode and a second electrode, the first electrode of the feedback capacitor being directly connected to the second electrode of the second transistor and the second electrode of the feedback capacitor being directly connected to the organic light emitting diode.
