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

Claim 0:
1. A sensing circuit, comprising:
a photo-sensing component, configured to receive a light and transmit a first current according to an intensity of the light;
a first transistor, a gate terminal of the first transistor being configured to receive a first control signal, wherein the photo-sensing component and the first transistor are coupled in series between a first node and a second node; and
a temperature-sensing component, coupled between the first node and the second node and configured to generate a second current according to a temperature, the temperature-sensing component comprising:
a channel structure, configured to transmit the second 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 second control signal;
a second gate, arranged below the channel structure and configured to control an intensity of the second current in the channel structure according to a third control signal; and
a light-shielding structure, arranged above the first gate and configured to shield the light coming from above the temperature-sensing component.
