Abstract:
1. A pixel comprising: an organic light emitting diode (OLED); a first transistor to control an amount of current supplied from a first power source coupled to a first electrode to the OLED; a second transistor coupled between a data line and a third node, the second transistor to be turned on when a first scan signal is supplied to a first scan line; a first capacitor coupled between a first node and a gate electrode of the first transistor and a second node; a sixth transistor coupled between the second node and the third node, the sixth transistor to be turned off when an emission control signal is supplied to an emission control line; a second capacitor coupled between the third node and the first power source; a fifth transistor coupled between the first power source and the second node, the fifth transistor to be turned on when the first scan signal is supplied to the first scan line; and a fourth transistor coupled between a second electrode of the first transistor and the data line, the fourth transistor to be turned on when a second scan signal is supplied to a second scan line, wherein the second transistor is simultaneously turned on with the fourth transistor and maintains a turn on state for a period of time longer than the fourth transistor.
