Abstract

A pixel includes a plurality of transistors, a storage capacitor, and an organic light emitting diode. A first transistor controls the amount of current from a first driving power source to the organic light emitting diode based on a data voltage. A second transistor is connected to a data line and is turned on based on a scan signal. A third transistor coupled to the first transistor and is turned on based on the scan signal. A first stabilizing transistor is coupled to the third transistor or between the first and third transistors and is turned off when the third transistor is turned off.
