Patent ID: 8111219

Claim:
A pixel, comprising: an OLED; a first transistor coupled between a data line and a first node, the first transistor being turned on by a low signal on an i-th scan line, i being a natural number; a second transistor coupled between a first power source and a fifth transistor, wherein: the second transistor has a gate electrode coupled to a second node, the fifth transistor is coupled between the second transistor and the OLED, and the fifth transistor is turned on by a low signal on an i-th emission control line; a third transistor coupled between the gate electrode of the second transistor and an electrode of the second transistor that is coupled to the fifth transistor, the third transistor being turned on by a low signal on an (i−1)-th scan line; a fourth transistor coupled between a first reference voltage and the first node, the fourth transistor being turned on by the low signal on the (i−1)-th scan line; a storage capacitor coupled between the first node and the second node; and a compensator controlling a voltage of the second node corresponding to degradation of the OLED, wherein the compensator includes: a feedback capacitor coupled between the first node and a third node; and a sixth transistor and a seventh transistor disposed in series between a second reference voltage and a fourth node, wherein: the third node is between the sixth and seventh transistors, and the fourth node is between the fifth transistor and the OLED.
