Abstract:
A pixel includes: an OLED; a first transistor having a first electrode coupled to a power source and a second electrode coupled to the OLED and configured to control a magnitude of current supplied to the OLED; a third transistor having a first electrode coupled a first node and a second electrode coupled to a gate electrode of the first transistor; a capacitor coupled between the first node and a second electrode of the first transistor; a second transistor having a first electrode coupled to the first node and a second electrode coupled to a data line and configured to be turned on when the third transistor is turned off; and a fourth transistor having a first electrode coupled to a gate electrode of the first transistor and a second electrode coupled to a reference power source and configured to be turned on and off concurrently with the second transistor.
