Abstract:
A display device according to the present disclosure includes: a pixel array unit ( 30 ) in which pixel circuits ( 20 A) are disposed in a matrix form, the pixel circuits each including a light emission unit ( 21 ), a write transistor ( 23 ) that writes a signal voltage (Vsig) of a video signal, a retention capacitor ( 24 ) that retains the signal voltage (Vsig) written by the write transistor ( 23 ), a drive transistor ( 22 ) that drives the light emission unit ( 21 ) on the basis of the signal voltage (Vsig) retained by the retention capacitor ( 24 ), and an auxiliary capacitor ( 25 ) of which one terminal is connected to a source node of the drive transistor ( 22 ); and a control unit ( 90 ) that provides a potential change to a source electrode of the drive transistor ( 22 ) by coupling through the auxiliary capacitor ( 25 ) to set an operation point of the drive transistor ( 22 ) as a cut-off region after the threshold value correction process.

Claim (Index 1):
A display device comprising:\n drive circuitry; and a plurality of pixels, wherein at least one of the plurality of pixels comprises: a light emitting element; a writing transistor; a first capacitor; and a driving transistor, wherein the writing transistor is electrically connected between a data signal line and a control terminal of the driving transistor, wherein the first capacitor is electrically connected between the control terminal of the driving transistor and a first terminal of the driving transistor, wherein the drive circuitry is configured to control the voltage of the first terminal of the driving transistor and set a second period that is equal to or longer than a first period, wherein the writing transistor is in an active state to supply an offset voltage from the data signal line to the control terminal of the driving transistor during the first period, and wherein the second period includes a third period in which the writing transistor is in an active state to supply a signal voltage of a video signal from the data signal line to the control terminal of the driving transistor.
