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.

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: This application provides a display panel, a preparation method therefor, and a display apparatus. A first display region of the display panel has an OLED pixel, a second display region has a Micro LED pixel, the Micro LED pixel has a light emitting region and a light transmission region, and a camera is disposed below the second display region. After the Micro LED pixel is used in the second display region, display pixels having a same area in the first display region and the second display region can be designed, to implement display effect consistency between the first display region and the second display region. Because a size of the Micro LED pixel for light emitting is small, it can be ensured that the Micro LED pixel has a large light transmission region, so that light transmittance of the second display region can be improved.
