Pixel of an organic light emitting diode display device, and organic light emitting diode display device

Abstract

A pixel of an organic light emitting diode display device includes a capacitor, a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor, an eighth transistor, a ninth transistor and an organic light emitting diode. The third transistor includes first and second sub-transistors which are coupled to each other in series between a drain of the first transistor and a gate node, and a fourth transistor includes third and fourth sub-transistors which are coupled to each other in series between a line of an initialization voltage and the gate node. The eighth transistor applies a reference voltage to a first node between the first and second sub-transistors in response to an emission signal, and a ninth transistor applies the reference voltage to a second node between the third and fourth sub-transistors in response to the emission signal.
