Abstract

A display module and a display device. The display module includes a display panel, which has a display region (AA) and a light-transmitting region (BB), the light-transmitting region (BB) being provided with a light-transmitting hole (V 1 ); a flexible cover plate, which is located on the light exit side of the display panel, and covers the display region (AA) and the light-transmitting region (BB); a transparent supporting structure, which is located on the side of the display panel facing the flexible cover plate, where the transparent supporting structure covers the light-transmitting hole (V 1 ), and an orthogonal projection of the transparent supporting structure on the flexible cover plate and an orthogonal projection of the display panel on the flexible cover plate have an overlapping region.

Claims (29)

1 . A display module, comprising:

a display panel, comprising a display region and a light-transmitting region, wherein the light-transmitting region has a light-transmitting hole;

a cover film arranged on a light-emitting side of the display panel and covering the display region and the light-transmitting region; and

a transparent supporting structure arranged on one side, facing the cover film, of the display panel;

wherein the transparent supporting structure covers the light-transmitting hole; and

an orthographic projection of the transparent supporting structure on the cover film and an orthographic projection of the display panel on the cover film have an overlapping region;

wherein the display module further comprises a polarizer arranged on one side, facing the cover film, of the display panel;

wherein the polarizer and the transparent supporting structure are arranged on a same layer; the polarizer is arranged around the transparent supporting structure; and a gap is provided between the polarizer and the transparent supporting structure;

wherein the display module further comprises a touch layer between the display panel and the polarizer; a gap is provided between the touch layer and the transparent supporting structure; and a thickness of the transparent supporting structure is equal to a total thickness of the polarizer and the touch layer in a thickness direction of the display panel.

2 . The display module according to claim 1 , wherein a material of the transparent supporting structure is transparent glass.

3 . The display module according to claim 1 , wherein the gap has a width greater than or equal to 0.45 mm in an extension direction of the cover film.

4 . The display module according to claim 1 , further comprising an optically clear adhesive layer arranged between the polarizer and the cover film;

wherein an orthographic projection of the optically clear adhesive layer on the cover film covers orthographic projections of the display region and the light-transmitting region on the cover film; and

the transparent supporting structure is bonded to the optically clear adhesive layer.

5 . The display module according to claim 1 , further comprising a light-shielding layer arranged on one side, facing the display panel, of the cover film;

wherein an orthographic projection of the light-shielding layer on the cover film covers part of the light-transmitting hole and an orthographic projection of a portion, adjacent to light-transmitting hole, of the display region on the cover film;

a first through hole is arranged in a position, corresponding to the light-transmitting hole, in the light-shielding layer; and

the first through hole has a smaller diameter than the light-transmitting hole.

6 . The display module according to claim 5 , wherein a central axis of the first through hole coincides with a central axis of the light-transmitting hole; and

an overlapping portion of the orthographic projections of the light-shielding layer and the transparent supporting structure on the cover film has a width greater than or equal to 0.4 mm.

7 . The display module according to claim 5 , wherein a material of the light-shielding layer is ink.

8 . The display module according to claim 1 , wherein in an extension direction of the cover film, a distance between an inner wall of the light-transmitting hole and a side edge of the transparent supporting structure is greater than or equal to 0.44 mm.

9 . The display module according to claim 1 , further comprising a back film arranged on one side, away from the cover film, of the display panel;

wherein the back film has a second through hole corresponding to the light-transmitting hole.

10 . The display module according to claim 9 , further comprising a supporting layer arranged on one side, away from the cover film, of the back film;

wherein the supporting layer has a third through hole corresponding to the light-transmitting hole; and

in an extension direction of the cover film, a distance between an inner wall of the third through hole and an inner wall of the light-transmitting hole is larger than 0.

11 . A display device, comprising the display module according to claim 1 .

12 . The display device according to claim 11 , further comprising a camera at least partially arranged in the light-transmitting hole.
