Abstract
A photoelectric detection circuit, a method of controlling the photoelectric detection circuit and a pixel unit are provided. The photoelectric detection circuit includes: a detection sub-circuit configured to generate a current flowing between a bias voltage signal terminal and a input node in response to an optical signal; a storage sub-circuit connected between the bias voltage signal terminal and the input node, and configured to store energy based on the current generated by the detection sub-circuit; an integrator sub-circuit having a first input terminal, a second input terminal and an output terminal, and configured to integrate a signal of the first input terminal based on a potential of the second input terminal to generate an integrated signal and output the integrated signal at the output terminal; and a control sub-circuit connected to a control signal terminal, the input node and the first input terminal of the integrator sub-circuit.
