Pixel and Organic Light Emitting Display Device Comprising the Same

Abstract:

A pixel for an organic light emitting display device includes an organic light emitting diode that emits light by a driving current, a driving transistor configured to control the driving current, a first transistor to connect the second node and the third node, a second transistor to apply a data voltage to the first node, a third transistor to apply a high-potential driving voltage to the second node, a fourth transistor that forms a current path between the driving transistor and the organic light emitting diode, a fifth transistor to apply an initial voltage to the driving transistor, a sixth transistor configured to apply a reset voltage to a fourth node which is an anode electrode of the organic light emitting diode, a seventh transistor configured to apply the high-potential driving voltage to the fifth node, and an eighth transistor configured to apply a reference voltage to the fifth node.
