Patent ID: 8059071

Claim:
A pixel comprising: an organic light emitting diode; a storage capacitor coupled between a first power supply and an initialization power supply and being charged with a voltage corresponding to a data signal; a first transistor controlling an amount of an electric current supplied to the organic light emitting diode corresponding to the voltage charged in the storage capacitor; a second transistor coupled between a data line and a current scan line, supplying the data signal to a first electrode of the first transistor when a scan signal is supplied to the current scan line; a third transistor coupled between a gate electrode and a second electrode of the first transistor, and being turned-on when the scan signal is supplied to the current scan line; a fourth transistor coupled between the first power supply and the first electrode of the first transistor, and being turned-on or turned-off according to an emission control signal supplied to an emission control line; a fifth transistor coupled between the second electrode of the first transistor and the organic light emitting diode, and being turned-on or turned-off according to the emission control signal supplied to the emission control line; a sixth transistor coupled between the initialization power supply and the storage capacitor, and being turned-on when the scan signal is supplied to a previous scan line; and a boosting capacitor having a first electrode coupled between the current scan line and a gate electrode of the second transistor and a second electrode coupled to the gate electrode of the first transistor and between the storage capacitor and the sixth transistor, boosting a voltage of the gate electrode of the first transistor when a supply of the scan signal to the current scan line stops, wherein a capacitance of the boosting capacitor is set to be less than the capacitance of the storage capacitor.
