Abstract: An interface display method is provided. The method includes: obtaining a first display position of a display shape of a front-facing sensor interaction component on a full-screen display; searching a configuration file for a target function icon corresponding to the front-facing sensor interaction component, where the configuration file includes a display position, on the full-screen display, of a function icon, and a second display position of the target function icon on the full-screen display is the same as or close to the first display position; and displaying a processed target function icon on the full-screen display, where a display position of the processed target function icon is the same as or close to the first display position, and a display shape of the processed target function icon is the same as or similar to the display shape of the front-facing sensor interaction component on the full-screen display.

Abstract: The present disclosure relates to display assemblies, display apparatuses, and fingerprint recognition methods. One example display assembly includes a display panel and a fingerprint recognition module located on a light-emitting surface of the display panel. The fingerprint recognition module includes multiple fingerprint recognition units. Each fingerprint recognition unit includes at least one phototransistor and one switch transistor. The phototransistor includes a first active layer, a first gate, a first source, and a first drain. A material for making the first active layer includes an organic semiconductor material. The first drain and the first gate partially overlap to form a first capacitor. The switch transistor includes a second active layer, a second gate, a second source, and a second drain. The fingerprint recognition module includes a first metal layer. The first source, the first drain, the second source, and the second drain are all located at the first metal layer.

Abstract: This application provides a display panel and an electronic device. A display region of the display panel is divided into at least two pixel regions. The pixel region includes at least two subpixels. The display region includes a first display region and a second display region. Subpixel density of the first display region is less than that of the second display region. In the first display region, at least some adjacent pixel regions have different structures. By changing structures of at least some pixel regions in the first display region, an arrangement rule of structures in pixel regions in the first display region is changed to some extent, and form a long-period diffraction grating or an aperiodic diffraction grating, so that a diffraction phenomenon caused by light passing through the display panel can be mitigated.

Abstract: A display panel module includes an organic light-emitting diode panel (OLED), a touch panel, and a bifurcated chip on film (COF). An OLED panel connection area is disposed at a first location on a first side of the OLED panel, and a touch panel connection area is disposed at a first location on a first side of the touch panel. The OLED panel connection area and the touch panel connection area are located at a same side of the display panel module. One bifurcated terminal of the bifurcated COF is connected to the OLED panel connection area, and the other bifurcated terminal of the bifurcated end of the bifurcated COF is connected to the touch panel connection area. The other end of the bifurcated COF is connected to a main flexible printed circuit. A chip of the bifurcated chip on film COF is a touch and display driver chip.

Abstract: A display screen adjustment method and apparatus, and a device are provided. A display screen includes a first display area and a second display area, a camera component is disposed under the first display area, and light transmittance of the first display area is higher than light transmittance of the second display area. The adjustment method includes: collecting present ambient illuminance on a terminal; and when the ambient illuminance is lower than an ambient illuminance threshold, adjusting, based on a first ambient light adaptation adjustment curve, luminance corresponding to grayscale 255 of the first display area to first luminance, and adjusting, based on a second ambient light adaptation adjustment curve, luminance corresponding to grayscale 255 of the second display area to second luminance, where the first luminance is approximately equal to the second luminance.
