Abstract: An electronic device and a control method are provided. The electronic device includes a sensing pixel. The sensing pixel includes a photosensitive element, a first transistor, a second transistor and a third transistor. The first transistor is coupled to the photosensitive element and for receiving a reset signal. The second transistor is coupled to the photosensitive element. The third transistor is coupled to the second transistor and for receiving a scan signal. During a reset period, a reset signal waveform of the reset signal and a first scan signal waveform of the scan signal are at least partially overlapped.

Abstract: An electronic device is provided. The electronic device includes: a substrate, a plurality of pixels, a plurality of data lines, an amplifier and a current source. The pixels and data lines are disposed on the substrate. The amplifier and the current source are coupled to one of the data lines, wherein at least a portion of the one of data lines forms a conduction path. One of the pixels is coupled to the one of the data lines at a first node, and the first node is on the first conduction path. A first current that flows from the first node to the first source terminal is different from a second current that flows from the first node to the first output terminal.
