Zusammenfassung:An electronic device including a plurality of sensing pixel circuits is provided. At least one of the sensing pixel circuits includes a photoelectric sensing element, a first transistor device, a second transistor device, a third transistor device and a fourth transistor device. The fourth transistor device includes a first end, a second end and a control end. The first end of the fourth transistor device is coupled to a first end of the first transistor device. The second end of the fourth transistor device is coupled to a bias voltage. The control end of the fourth transistor device is coupled to a scan line. The fourth transistor device serves as a current sink in a pre-trap period.
