Abstract:
1. A pixel comprising: an organic light emitting diode coupled between a first power supply and a second power supply having a lower voltage than the first 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 a first electrode of the first transistor and a data line and having a gate electrode coupled to a scan line; a third transistor coupled between a second electrode of 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; 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; and a capacitor coupled between the first node and the second power supply, wherein the first, second, third, fourth, and fifth transistors are N-type transistors.
