ABSTRACT:
A pixel for compensating for the threshold voltage of a drive transistor and the voltage drop of a first power source is provided. The pixel includes an organic light emitting diode; a driving transistor coupled between a first power source and the organic light emitting diode for controlling the current supplied to the organic light emitting diode; an emission control transistor coupled between a first electrode of the driving transistor and the first power source and configured to be turned off when a high light emission control signal is applied; a switching transistor coupled between a gate electrode of the driving transistor and a data line and configured to be turned on when a low scan signal is applied; a first capacitor coupled between the gate electrode of the driving transistor and the first electrode of the driving transistor; and a second capacitor coupled between the first electrode of the driving transistor and the first power source.
