Abstract:
A pixel includes: a first transistor connected between a data line and a first node; a second transistor connected between a first power source and a second node, the second transistor including a gate electrode connected to the first node; a third transistor connected between the first power source and the second transistor; a capacitor connected between the first node and the second node; an organic light emitting diode (OLED) connected between the second node and a second power source; and a fourth transistor including a second electrode connected to a cathode of the OLED.
