Abstract

A display device includes a pixel array unit that is formed by disposing pixel circuits that include a P-channel type drive transistor that drives a light-emitting unit, a sampling transistor that applies a signal voltage, a light emission control transistor that controls light emission and non-light emission of the light-emitting unit, a storage capacitor that is connected between a gate electrode and a source electrode of the drive transistor and an auxiliary capacitor, a first end of which is connected to the source electrode of the drive transistor, and a drive unit that, during threshold correction, applies a standard voltage that is used in threshold correction to the gate electrode of the drive transistor in a state in which the source electrode of the drive transistor has been set to a floating state, and subsequently applies a pulse signal to a second end of the auxiliary capacitor.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Japanese Priority Patent Application JP2013-142832 filed on Jul. 8, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a display device, a driving method for the display device, and an electronic device, and in particular, to a planar type (panel type) display device formed of pixels including light emitting units arranged in rows and columns (matrix form), a A driving method for a display device and an electronic device including the display device. Background technique [0004] A display device using a so-called current-driven photoelectric element in which light emission luminance is changed in accordance with a value of current flowing to a light emitting unit (light emitting element) that is a light emitting unit of a pixel is a flat type display device. For example, an organic electroluminescen...
