ABSTRACT:
A pixel and an organic light emitting display using the same, which reduces the number of output lines in a data driver and stably express black gradation. The pixel includes 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 a data signal to be provided to the data line 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; and a boosting capacitor coupled between the current scan line and the gate electrode of the first 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.
