Classification: CPC G  H | IPC G

Claim 0:
1. A display device provided with a pixel circuit including a display element driven by a current, the display device comprising:
a display unit that includes
a plurality of the pixel circuits of a plurality of rows and a plurality of columns,
a plurality of data signal lines configured to supply data signals to a plurality of the pixel circuits in corresponding respective columns,
a plurality of scanning signal lines configured to control writing of the data signals into a plurality of the pixel circuits in corresponding respective rows, and
a plurality of light-emission control lines configured to control whether to supply a current to the display element included in each of a plurality of the pixel circuits in the corresponding respective rows; and
a proximity sensor that includes
an emitting unit configured to emit infrared light from a back surface of the display unit, and
a light receiving unit configured to receive reflected light of the infrared light, wherein
in a display period during which an image is displayed on the display unit, the emitting unit emits the infrared light only in a period including a part of an infrared light irradiation region turn-off period during which the plurality of light-emission control lines are driven such that no current is supplied to the display element included in each of a plurality of the pixel circuits in each of rows corresponding to an infrared light irradiation region that is irradiated with the infrared light, the period being before a time point at which writing of the data signals into a plurality of the pixel circuits in each of rows corresponding to the infrared light irradiation region is started.
