Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 12:
13. A pixel circuit, comprising:
a sensing circuit, comprising:
a semiconductor device, coupled between a first node and a second node, the semiconductor device comprising:
a channel structure, configured to transmit a first current;
a first gate, arranged above the channel structure and configured to control the channel structure to operate in an off state according to a first control signal;
a second gate, arranged below the channel structure and configured to control an intensity of the first current in the channel structure according to a second control signal; and
a light-shielding structure, arranged above the first gate and configured to shield a light coming from above the semiconductor device;
wherein, in response to the second gate controlling the first current in the channel structure, the semiconductor device is configured as a temperature-sensing component; and
in response to the second gate controlling the first current in the channel structure, the semiconductor device is configured as a switch component,
wherein the first current in a first period that the semiconductor device is configured as the temperature-sensing component is larger than the first current in a second period that the semiconductor device is configured as the switch component.
