Claim:
1. A pixel, comprising: an organic light emitting diode (OLED); a pixel circuit that controls an amount of current supplied from a first power source to the OLED based on a data signal; at least one first transistor in a current path between the first power source and the OLED; and a second transistor coupled between a gate electrode of the at least one first transistor and an emission control line through which an emission control signal is supplied; a gate electrode of the second transistor coupled to a first node, wherein: the emission control signal controls a state of the at least one first transistor, and the second transistor turns on or off based on a voltage level of the first node, wherein when the second transistor is turned on, the emission control line is electrically connected to the gate electrode of the at least one first transistor through the second transistor being turned on, and wherein the pixel circuit includes third, fourth, and fifth transistors, the third transistor provided in the current path between the first power source and the OLED, the third transistor controlling the amount of current supplied to the OLED based on a voltage applied to the first node; the fourth transistor coupled between a first electrode of the third transistor and a data line, the fourth transistor to turn on when a scan signal is supplied to a first scan line; and the fifth transistor coupled between a second electrode of the third transistor and the first node, the fifth transistor to turn on when the scan signal is supplied to the first scan line.
