ABSTRACT:
A pixel includes an organic light emitting diode, a first transistor coupled to a scan line and a data line, the first transistor being configured to receive a data signal via the data line when a scan signal is supplied to the scan line, a storage capacitor configured to store voltage corresponding to the data signal received by the first transistor, a second transistor configured to control an electric current from the first power source to the second power source via the organic light emitting diode with respect to the voltage stored in the storage capacitor, and compensation unit configured to adjust voltage at a gate electrode of the second transistor, the voltage adjustment being sufficient to compensate for a deterioration degree of the organic light emitting diode.
