Title:
PIXEL CIRCUIT, DISPLAY DEVICE, AND INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/059867
Kind Code:
A8
Abstract:
Compensate for the variations of threshold voltage of a driving transistor. During the period of the reference signal voltage Vref being set to the signal line DTC, voltage between the gate and source of the driving transistor IOC is made equal to or greater than the threshold voltage of the driving transistor IOC, and the difference in voltage of the reference signal voltage Vref and the reference power supply voltage VreCr is charged to the retentive capacitance IOB. At the same time, the voltage of the source of the said driving transistor IOC is set to the reference power supply voltage VreCr to make the voltage applied to the said light emitting elements equal to or lower than its threshold voltage. Subsequently, while maintaining the voltage applied to the said light emitting elements IOE equal to or lower than its threshold voltage.
