Abstract:
1. A pixel comprising: an organic light emitting diode coupled between a first power supply and a second power supply, the first power supply having a higher voltage than the second power supply; a first transistor coupled between the organic light emitting diode and the second power supply, and for controlling a driving current that flows from the first power supply to the second power supply via the organic light emitting diode; a second transistor coupled to a first node to which a gate electrode of the first transistor is coupled, and for bringing the first node to a first voltage in accordance with a first scan signal; a first capacitor coupled between the first node and a second node; a third transistor coupled between the second node and a data line, and for supplying a data signal from the data line to the second node in accordance with the first scan signal; a fourth transistor coupled between the first node and the second node, and for coupling the first node to the second node in accordance with a second scan signal; a fifth transistor coupled between the first transistor and the second power supply, and for coupling the first transistor to the second power supply in accordance with an emission control signal; and a second capacitor coupled between the second node and a third node between the first transistor and the fifth transistor.
