Abstract
A photoelectric detection circuit and a photoelectric detector are provided. The photoelectric detection circuit includes a first sub-circuit and a second sub-circuit. The first sub-circuit includes a first photoelectric sensing element, and the second sub-circuit includes a second photoelectric sensing element, and an electrical characteristic of the first photoelectric sensing element is substantially identical to an electrical characteristic of the second photoelectric sensing element, and the second photoelectric sensing element is shielded to prevent light from being incident on the second photoelectric sensing element.
