PIXEL AND ORGANIC LIGHT EMITTING DISPLAY |
摘要 |
A pixel at an ith pixel row (i is a natural number) includes an organic light emitting diode (OLED); a driving transistor for supplying a current to the OLED and a storage capacitor between a gate electrode of the driving transistor and an (i-1)th emission control line; and a compensating unit for controlling a voltage of the gate electrode of the driving transistor to compensate for deterioration of the OLED. The compensating unit includes: a first compensating unit transistor and a second compensating unit transistor between the OLED and a first power source; first and second feedback capacitors between a second node between the first and second compensating unit transistors and a first node between the gate electrode of the driving transistor and the storage capacitor; and a third compensating unit transistor coupled between a third node between the first and second feedback capacitors and a reference voltage source.
