Patent ID: 8242981

Claim:
A pixel comprising: an organic light emitting diode having an anode electrode and a cathode electrode; a second transistor for controlling an amount of current supplied from a first power supply to a second power supply via the organic light emitting diode; a first transistor coupled between a gate electrode of the second transistor and a data line and configured to turn on when a scan signal is supplied to a scan line; a first capacitor coupled between the first power supply and the gate electrode of the second transistor; a second capacitor electrically connected between a source electrode of a fourth transistor and the gate electrode of the second transistor; the fourth transistor coupled between the second capacitor and the anode electrode and configured to turn on when a control signal is supplied to a control line; and a third transistor coupled between the second transistor and the anode electrode and configured to turn off when a light emitting control signal is supplied to a light emitting control line.
