Abstract: 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.

Abstract: The present application discloses a sensing panel, and a display device and a driving method thereof. The sensing includes a base substrate; a plurality of photosensitive units arranged in an array on the base substrate; and a plurality of pressure-sensitive units arranged in an array on the base substrate. The photosensitive units and the pressure-sensitive units are integrated in a same sensing panel, and are stacked and share a fixed-potential electrode. As such, after loading a fixed potential to the fixed-potential electrode, the pressure detection and the touch detection can be achieved simultaneously with the same sensing panel.
