Abstract
A pixel and organic light emitting display device. The pixel includes an organic light emitting diode, first through fourth transistors, and a second capacitor. The fourth transistor is for controlling an amount of current flowing through the organic light emitting diode. A first transistor is coupled between a second terminal of the second capacitor and a data line and is configured to turn on in response to a scan signal supplied to an i-th scan line. A second transistor is coupled between a first terminal of the second capacitor and an initial power source and is configured to turn on in response to an other scan signal supplied to an (i−1)-th scan line. A third transistor is coupled between the second terminal of the second capacitor and a reference power source and is configured to turn off in response to an emission control signal supplied to an (i+1)-th emission control line.
