Abstract: A backlight module, a display module, and a display device are provided. The backlight module includes a light-emitting area including a first light-emitting area and a second light-emitting area. The second light-emitting area at least partially surrounds the first light-emitting area. The backlight module also includes a light-emitting structure including a plurality of light-emitting elements distributed in the light-emitting area, and a diffusion plate located on a side of a light exiting surface of the light-emitting structure and at least partially located in the light-emitting area. The backlight module also includes a reflection structure located on a surface of the diffusion plate facing the light-emitting structure. The reflection structure overlaps with the first light-emitting area.

Abstract: A light-emitting panel and a display apparatus are provided in the present disclosure. The light-emitting panel includes light-emitting units, where the light-emitting unit includes a pixel circuit and a light-emitting element which are electrically connected to each other, the light-emitting element includes light-emitting parts, and a plurality of light-emitting parts in one light-emitting element includes first and second light-emitting parts; and a substrate, where a collimation structure is on a side of the first light-emitting part away from the substrate, and an orthographic projection of the collimation structure on the substrate is overlapped with an orthographic projection of the first light-emitting part on the substrate. In the first light-emitting mode, the pixel circuit only controls the first light-emitting part of the light-emitting element to emit light; and in the second light-emitting mode, the pixel circuit at least controls the second light-emitting part of the light-emitting element to emit light.
