Title:
DISPLAY DEVICE, DRIVE METHOD FOR DISPLAY DEVICE, AND ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2014/103500
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a display device that can reliably control a light emitting unit in a non-light emitting state during a non-light emitting period, a drive method for the same, and electronic equipment having this display device.
This display device is formed by disposition of a pixel circuit having: a P channel type drive transistor that drives the light emitting unit; a sampling transistor that samples signal potential; a light emission control transistor that controls light emission/non-light emission of the light emitting unit; a retention capacitance that is connected between the gate electrode and source electrode of the drive transistor and retains a signal potential written through sampling by the sampling transistor; and an auxiliary capacitance connected between the source electrode of the drive transistor and a fixed potential node. The display device is provided with a current pathway for making current flowing in the drive transistor during the non-light emitting period for the light emitting unit flow to a prescribed node.
