Patent ID: 8400377

Claim:
A pixel comprising: an organic light emitting diode; a first transistor having a second electrode coupled to the organic light emitting diode and a first electrode coupled to a data line; a second transistor coupled between a gate electrode and the second electrode of the first transistor and turned-on when a first scan signal is supplied to a first scan line; a third transistor coupled between the first electrode of the first transistor and the data line and turned-on when a second scan signal is supplied to a second scan line; a first capacitor coupled between the first electrode of the first transistor and a first power supply; and a second capacitor coupled between the gate electrode of the first transistor and the first power supply, wherein the data line is configured to receive a data signal from a data driver and a first power from the first power supply at different times, wherein the organic light emitting diode is coupled between the first transistor and a second power supply, and wherein the second power supply is configured to supply a second power at a first level for an initialization period and a scan period of a frame, and to supply the second power at a second level that is lower than the first level for an emission period of the frame.
