Abstract: The present application discloses a display panel and a display device. The display panel includes a fingerprint recognition area. The display panel includes a cover plate and an optically transparent layer. The optically transparent layer at least covers a portion of the cover plate located in the fingerprint recognition area. A refractive index of the optically transparent layer is greater than a refractive index of air and less than a refractive index of a finger. A thickness of the optically transparent layer is an even multiple of a half-wavelength of a fingerprint recognition light ray. Half-wave loss and interference of light are used to improve fingerprint recognition performance.

Abstract: A method, device, and display device for detecting ambient light are provided. The method includes obtaining brightness information of the ambient light, determining a brightness interval of the ambient light according to the brightness information of the ambient light and preset correspondences between a plurality of ambient light sensors and different brightness intervals, using the ambient light sensor corresponding to the brightness interval of the ambient light as a reference sensor, and outputting a brightness signal of a current ambient light according to output signals of the ambient light sensors and a preset conversion formula.

Abstract: A display panel and a display device are provided. The display panel includes a fingerprint identification module. The fingerprint identification module includes a light sensor and a light-shielding layer disposed on a light incident side of the light sensor. The light-shielding layer is provided with a light-transmitting hole. A light filter structure is disposed in the light-transmitting hole. The display panel and the display device can filter out red light and near-infrared light entering the fingerprint identification module, so that the display panel can successfully perform fingerprint identifications even in a strong light environment.

Abstract: Display panel and display device are provided. The display panel includes a first display area and a second display area adjacent to the first display area. The second display area is multiplexed as a photosensitive element setting area. The first display area includes a plurality of first pixels arranged in an array. The second display area includes a plurality of second pixels arranged in an array. A first pixel of the plurality of first pixels includes a plurality of first sub-pixels. A second pixel of the plurality of second pixels includes a first area and a second area. The first area includes a plurality of second sub-pixels. The second area is in an open state when a photosensitive element is in operation. The second area is in a closed state when the display panel is in a full screen display.
