Pixel and organic light emitting display device using the same

摘要

A pixel includes an organic light emitting diode, a first transistor that controls an amount of current supplied to the organic light emitting diode, a second transistor connected between a gate electrode of the first transistor and an initialization power supply, and a third transistor diode-connected between an anode electrode of the organic light emitting diode and the initialization power supply.
