ABSTRACT:
A pixel configured to compensate for a threshold voltage of a driving transistor and including an organic light emitting diode coupled between a first power supply and a second power supply; a first transistor coupled between the organic light emitting diode and the second power supply and having a gate electrode coupled to a first node; a second transistor coupled between the first transistor and a data line and having a gate electrode coupled to a scan line; a third transistor coupled between the first transistor and the first node and having a gate electrode coupled to the scan line; a fourth transistor coupled between the first transistor and the second power supply and having a gate electrode coupled to an emission control line; and a fifth transistor coupled between the organic light emitting diode and the first transistor and having a gate electrode coupled to the emission control line.
