Patent ID: 7310078

Claim:
A pixel comprising: an organic light emitting diode; a first transistor for supplying an electric current to the organic light emitting diode, the electric current corresponding to a voltage signal transmitted to a gate terminal of the first transistor; a storage capacitor for supplying a stored voltage to the gate terminal of the first transistor; a second transistor coupled to a scan line and a data line and for charging the storage capacitor with a voltage corresponding to a data signal applied to the data line when a scan signal is supplied to the scan line; a third transistor coupled between the first transistor and the organic light emitting diode and having a gate terminal coupled to a gate terminal of the first transistor; a fourth transistor coupled between the gate terminal and a second terminal of the first transistor to couple the first transistor in a diode configuration when the scan signal is being supplied to a gate terminal of the fourth transistor; and a fifth transistor coupled between a first power supply and a first terminal of the first transistor and controlled by a light emitting control signal supplied from a light emitting control line.
