Abstract: The present disclosure relates to a display method. In one example method, a display is covered by a transparent panel. A location on the transparent panel and corresponding to a first area of the display has a cylindrical curved surface. An optical deformation parameter of a first area of the display is obtained. According to the optical deformation parameter of the first area, a shape of first image data is converted to obtain second image data. The first image data is image data to be displayed in the first area. The second image data is displayed in the first area.

Abstract: Embodiments relate to a display screen, including a cathode metal layer, an encapsulating layer disposed on an upper surface of the cathode metal layer, and an organic light-emitting layer disposed on a lower surface of the cathode metal layer. The organic light-emitting layer includes a non-light-emitting region and a plurality of light-emitting regions. The display screen further includes a light shielding layer. The light shielding layer is disposed on an upper surface of the encapsulating layer, and the light shielding layer is used to shield the non-light-emitting region of the organic light-emitting layer.

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.
