Abstract:
1. An optical sensor device comprising: a first substrate; a plurality of optical sensor units two-dimensionally arranged on a surface of the first substrate; a scan driver which sets the optical sensor units disposed in each row in a selected state; and a detection driver which acquires detection signals corresponding to illuminance of incident light on the optical sensor units set in the selected state, wherein each of the optical sensor units comprises a first optical sensor including a first photoelectric conversion section blocked from light and a second optical sensor including a second photoelectric conversion section configured to change the illuminance in response to an externally applied external force, and the detection driver maintains each voltages of electrodes of the first optical sensors and each voltages of electrodes of the second optical sensors, which are set in the selected state, in equal voltage levels to each other, and acquires a plurality of voltage signals in parallel as the detection signals, wherein each of the voltage signals corresponds to current flowing in accordance with the illuminance on each of the second optical sensors set in the selected state.
