Abstract: A display screen, a terminal, and a backlight system, where the backlight system includes a substrate, a plurality of spot light sources, an optical conversion layer, and a light mixing member, where the spot light sources are fastened onto the substrate in a mutually spaced manner. The optical conversion layer is stacked on the substrate and covers the spot light sources. The optical conversion layer is configured to convert, into a white surface light source, light emitted by the spot light sources. The light mixing member is located on a surface of the optical conversion layer or embedded into the optical conversion layer. The light mixing member is configured to mix the light. The backlight system emits light evenly and has a relatively small thickness.

Abstract: The technology of this disclosure relates to a stacked structure, a display screen, and a display apparatus. The stacked structure includes a substrate, a drive chip, and a pixel unit that are stacked. The substrate has a first surface. A line layer is disposed on the first surface, the drive chip is disposed on a surface that is of the line layer and that faces away from the first surface, and the pixel unit and a corresponding drive chip are stacked. A sub-pixel located in each pixel unit is separately electrically connected to the line layer and the corresponding drive chip to form a light-emitting loop.
