Abstract: Embodiments of this application provide an organic light-emitting display panel and a display apparatus. A functional layer disposed on a first substrate in the organic light-emitting display panel includes an emissive layer and an optical filter layer. A pixel define layer is disposed between adjacent organic light-emitting units in the emissive layer. Black light-shielding blocks and color-blocking blocks in the optical filter layer are alternately arranged. The color-blocking blocks and the organic light-emitting units are disposed in a one-to-one correspondence manner. A region between adjacent black light-shielding blocks covers the organic light-emitting unit in a thickness direction of the organic light-emitting display panel. The pixel define layer is a black light-absorbing layer. The black light-shielding blocks and the color-blocking blocks in the organic light-emitting display panel and the display apparatus provided in embodiments of this application, may cooperate to reduce transmission of visible light from an external environment to an internal film layer of the organic light-emitting display panel, and allow light emitted by the organic light-emitting unit to pass through. Therefore, a reflectivity of the organic light-emitting display panel to external ambient light is reduced, and luminance of the organic light-emitting display panel is not reduced.

Abstract: This application provides a display screen, a display screen protective film, and an electronic device. A transmissive layer of the display screen has a first surface away from a display panel, an orthographic projection of each micro structural unit on the first surface and along a thickness direction is located in a pixel region, and a projection area of the micro structural unit is less than or equal to an area of the pixel region. The micro structural unit may be a curved surface. In this embodiment of this application, the pixel region may include a region in which a sub-pixel is located on the display panel, and a spaced region between the sub-pixel and another sub-pixel that is located around the sub-pixel and adjacent to the sub-pixel. In the foregoing display screen, each micro structural unit mainly bends a display light ray of one sub-pixel. This helps reduce a difference in light refraction degrees between different sub-pixels, and further helps optimize a flash point.
