Patent ID: 8907870

Claim:
A pixel, comprising: an organic light emitting diode having a cathode electrode coupled to a second power supply; a first transistor for controlling an amount of current flowing from a first power supply to the second power supply through the organic light emitting diode; a second transistor coupled to a data line and turned on when a scan signal is supplied to an i th (i is a natural number) scan line; a third transistor coupled between the second transistor and a gate electrode of the first transistor and turned on when a scan signal is sequentially supplied to an i+1 th scan line after the scan signal is supplied to the i th scan line; a fourth transistor coupled between the gate electrode of the first transistor and a reference power supply and turned on when the scan signal is supplied to i th the scan line; a fifth transistor coupled between an anode electrode of the organic light emitting diode and an initial power supply and turned on when a control signal is supplied to a control line; a first capacitor coupled between the anode electrode of the organic light emitting diode and a node between the second transistor and the third transistor; and a second capacitor separate from the third transistor and coupled between the node and the gate electrode of the first transistor.
