Abstract: A display panel includes a substrate, a photoelectric detector, and a display surface. The photoelectric detector is located on a side that is of the substrate and that is close to the display surface. The photoelectric detector includes a PN junction or a PIN junction. The photoelectric detector is configured to be reverse biased or zero biased when the display apparatus works in an ambient light detection stage to generate a photo-generated current under illumination of ambient light and detect ambient light information. The photoelectric detector is disposed above the substrate, and ambient light needs to penetrate only a part of a film layer structure of the display panel to be received by the photoelectric detector.
