Abstract
A pixel of an OLED display device includes a first capacitor, a second capacitor, a first transistor configured to generate a driving current, a second transistor configured to transfer a data voltage to a first node, a third transistor configured to diode-connect the first transistor, a fourth transistor configured to transfer an initialization voltage to the second node, a fifth transistor configured to transfer a reference voltage to the first node, a sixth transistor configured to couple a drain of the first transistor and an anode of an organic light emitting diode, a seventh transistor configured to transfer the initialization voltage to the anode of the organic light emitting diode, an eighth transistor configured to transfer the initialization voltage to the drain of the first transistor, and the organic light emitting diode.
