Abstract: An LED light-emitting module is provided, including a glass substrate, a drive circuit, an LED light-emitting assembly, and a drive chip. The drive circuit is disposed on a side surface of the glass substrate. The LED light-emitting assembly includes a plurality of LED light sources arranged in an array manner. The LED light-emitting assembly is disposed on a surface of the drive circuit and is electrically connected to the drive circuit. The drive chip is connected to the drive circuit, and controls, by using the drive circuit, the LED light source in the LED light-emitting assembly to be turned on or off.

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.
