Display module and display device are provided. The display module includes: a display panel; a backlight module; a through hole; a first optical film, and a light-filling component. An orthographic projection of the first optical film on the display panel is located inside an orthographic projection of the through hole on the display panel. The first optical film is provided with a first microstructure on a side facing the light-filling component, and further includes a first hollowed portion penetrating through the first optical film along the direction perpendicular to the light-exiting surface of the display panel. Light emitted by the light-filling component at least partially enters the first hollowed portion through the first optical film, and is transmitted to the display panel. The first microstructure includes a plurality of annular substructures, and a center of each of the plurality of annular substructures is located in the first hollowed portion.

Display modules and display devices

An LED backlight, a backlight module, and a display apparatus are provided. The LED backlight includes: a substrate; a plurality of LED chips disposed on a first surface of the substrate and electrically connected to the substrate, where each LED chip includes a first light emitting surface disposed on a side of the LED chip facing away from the substrate and at least one second light emitting surface, and a plane where the at least one second light emitting surface is located intersects with the substrate; a plurality of prism-shaped light guide structures disposed between adjacent LED chips and in a space defined between two adjacent second light emitting surfaces of adjacent LED chips, where the prism-shaped light guide structures have an index of refraction of n1; and a first medium filling the space between the LED chips and the prism-shaped light guide structures.
