Abstract:
1. A display device in which a plurality of optical sensors are arranged in a display region, the display device comprising: a display panel that includes a plurality of display pixel circuits and a plurality of sensor pixel circuits; a light source that is turned on for a predetermined time in a one-frame period; and a drive circuit that outputs, to the sensor pixel circuits, a first control signal indicating a sensing period at time when the light source is turned on and a second control signal indicating a sensing period when the light source is turned off, and performs reset for and read from the sensor pixel circuits, wherein the sensor pixel circuits include: the drive circuit performs the read from the first and second sensor pixel circuits in a line sequential manner during a period other than the sensing period when the light source is turned on and the sensing period when the light source is turned off.
