发明名称 Optical sensor device, display apparatus, and method for driving optical sensor device
摘要 An optical sensor device includes a plurality of optical sensor units two-dimensionally arranged, a scan driver, and a detection driver. The scan driver sets optical sensor units, in each row, in a selected state. The detection driver acquires detection signals corresponding to illuminance of incident light on the optical sensor units. 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. The detection driver maintains each voltage of electrodes of the first optical sensors and each voltage of electrodes of the second optical sensors in equal voltage levels to each other, and acquires a plurality of voltage signals in parallel.
