摘要：
A pixel driving method for an organic light emitting device includes charging a data voltage supplied through a data line to a storage capacitor and driving an N-channel switching transistor while cutting off supply of an upper power supply voltage to an organic light emitting diode; and powering the organic light emitting diode emit light by driving the N-channel driving transistor by the data voltage charged onto the storage capacitor while supplying the upper power supply voltage to the light emitting diode.
