摘要： A light detection circuit, an electronic device, and an optical recognition method are provided. The light detection circuit includes a charge storage sub-circuit (10), a photoelectric conversion sub-circuit (30), a signal collection sub-circuit (40), and a potential pull-up sub-circuit (50). When a potential of a reading node (A) is decreased by a preset value, the potential pull-up sub-circuit (50) changes the potential of the reading node (A) to an initial potential. A photoelectric diode may continuously generate a light current under the action of light, so that the potential of the reading node (A) is decreased again. Even when the intensity of ambient light is high, a touch can be accurately recognized in an optical touch recognition circuit, and ridge lines and valley lines can be accurately recognized in an optical fingerprint recognition circuit.
