Abstract

The present invention provides a display module and a fixing method therefor, and a display apparatus. The display module is provided with a light-shielding structure including a light-shielding part and a supporting part that are integrally formed, wherein the light-shielding part is arranged around the inner wall of a through hole; the supporting part is fixed to a side of a display panel away from a cover plate; and an orthographic projection of the light-shielding part on the cover plate and an orthographic projection of a light-shielding layer on the cover plate at least partially overlap, such that a transition area is surrounded by the light-shielding layer and the light-shielding part in a through hole area.

First claim

What is claimed is:

1 . A display module, comprising:
a display panel comprising a display region, a transition region and a through hole region, wherein the transition region is located between the display region and the through hole region; and the through hole region has a through hole penetrating through a thickness direction of the display panel; a cover plate located on a light emitting side of the display panel; a light-shielding layer located in the transition region and located on a side of the cover plate facing the display panel; a light-shielding structure comprising a light-shielding part and a supporting part that are integrally formed, wherein the light-shielding part is disposed in the through hole, and the supporting part is fixed to a heat dissipation structure on a side of the display panel away from the cover plate, wherein an inner edge of the heat dissipation structure defines a portion of the inner wall of the through hole a camera at least partially located in the through hole, wherein an orthographic projection of the light-shielding layer on the cover plate and an orthographic projection of the camera located in the through hole on the cover plate do not overlap, and an orthographic projection of the light-shielding part on the cover plate and the orthographic projection of the light-shielding layer on the cover plate at least partially overlap; wherein the light-shielding part is not in contact with either of the light-shielding layer and the inner wall of the through hole.

2 . The display module according to claim 1 , wherein a distance between the light-shielding part and the inner wall of the through hole is 0.1 mm-0.25 mm.

3 . The display module according to claim 1 , wherein a distance between the light-shielding part and the light-shielding layer is less than 0.1 mm.

4 . The display module according to claim 1 , wherein an interval between an edge, adjacent to the through hole region, of the orthographic projections of the light-shielding part and an edge, adjacent to the through hole region, of the orthographic projections of the light-shielding layer on the cover plate is 0.05 mm-0.2 mm.

5 . The display module according to claim 1 , wherein the supporting part is fixed to the side of the display panel away from the cover plate by a double-sided tape.

6 . The display module according to claim 5 , wherein an orthographic projection of the double-sided tape on the cover plate is located within a range of an orthographic projection of the supporting part on the cover plate.

7 . The display module according to claim 6 , wherein a distance between a side edge of the double-sided tape away from the through hole and a side edge of the supporting part away from the through hole is 0.2 mm-0.5 mm, and a distance between a side edge of the double-sided tape close to the through hole and the light-shielding part is 0.2 mm-0.5 mm.

8 . The display module according to claim 1 , wherein a material of the light-shielding structure is metal, and the light-shielding structure is formed by stamping.

9 . The display module according to claim 1 , wherein a material of the light-shielding structure is plastic, and the light-shielding structure is formed by injection molding.

10 . The display module according to claim 1 , further comprising: a touch panel located between the cover plate and the display panel, a polarizer located between the touch panel and the cover plate, a first adhesive layer and a second adhesive layer; wherein the touch panel and the display panel are bonded through the first adhesive layer, and the polarizer and the cover plate are bonded through the second adhesive layer.

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

12 . A fixing method for the display module according to claim 1 , comprising:
providing a light-shielding structure, wherein the light-shielding structure comprises a light-shielding part and a supporting part that are integrally formed, and a surface of the supporting part fixed to a display panel comprises a double-sided tape and a protective film located on an outer side of the double-sided tape; and tearing off the protective film, disposing the light-shielding part around an inner wall of a through hole by using an alignment equipment, and fixing the supporting part to a side of the display panel away from a cover plate by the double-sided tape.

13 . The fixing method according to claim 12 , wherein the disposing the light-shielding part around the inner wall of the through hole by using the alignment equipment, and fixing the supporting part to the side of the display panel away from the cover plate by the double-sided tape, comprises:
absorbing an edge region of the supporting part by a suction nozzle of the alignment equipment, installing, by the suction nozzle, the light-shielding part into the through hole, and pressing the supporting part by a pressure head of the alignment equipment so as to fix the supporting part to the side of the display panel away from the cover plate.
