Abstract

The present application provides a display module and a display device, the display module includes a bending zone and a non-bending zone which are adjacently arranged; the display module includes a flexible screen and a support component which are laminated, and the support component is located on a backlight side of the flexible screen; the support component is provided with a first groove, and the first groove is located on a side of the bending zone close to the non-bending zone. The first groove may reduce the rigidity of the support component on the side of the bending zone close to the non-bending zone and alleviate the crease in the support component, preventing the crease of this part of the support component from being too sharp and thus alleviating the crease of the display module.

First claim

What is claimed is:

1 . A display module, comprising a bending zone and a non-bending zone, the bending zone and the non-bending zone being adjacently arranged along a first direction; and comprising:
a flexible screen; and a support component laminated on the flexible screen, located on a backlight side of the flexible screen and provided with a first groove located on a side of the bending zone close to the non-bending zone.

2 . The display module according to claim 1 , wherein the bending zone comprises:
a first bending zone; and a second bending zone located between the first bending zone and the non-bending zone; the first groove is located in the second bending zone.

3 . The display module according to claim 1 , wherein an opening of the first groove is located on a surface of a side of the support component facing away from the flexible screen.

4 . The display module according to claim 1 , wherein an opening of the first groove is located on a surface of a side of the support component facing the flexible screen.

5 . The display module according to claim 1 , further comprising:
an adhesive component disposed in the first groove.

6 . The display module according to claim 1 , wherein, along the first direction, a length of an opening of the first groove ranges from 0.5 mm to 3 mm.

7 . The display module according to claim 1 , wherein a groove depth of the first groove is less than or equal to 0.1 mm.

8 . The display module according to claim 2 , wherein, along the first direction, the first bending zone comprises a central zone and two edge zones located respectively on two opposite sides of the central zone, and a rigidity of a part of the support component located in the edge zone is greater than a rigidity of a part of the support component located in the central zone.

9 . The display module according to claim 8 , wherein a rigidity of a part of the support component located in the second bending zone is greater than the rigidity of the part of the support component located in the edge zone.

10 . The display module according to claim 8 , wherein, along the first direction, a length of the central zone ranges from 1 mm to 5 mm.

11 . The display module according to claim 8 , wherein, along a thickness direction of the support component, the support component comprises a first surface and a second surface which are opposite to each other, and the part of the support component located in the central zone is provided with at least a second groove, and at least one of the first surface and the second surface of the support component is provided with an opening of the at least a second groove.

12 . The display module according to claim 11 , wherein, along the first direction, a length of the opening of the at least a second groove ranges from 0.5 mm to 1 mm.

13 . The display module according to claim 11 , wherein a groove depth of the at least a second groove is less than or equal to 0.1 mm.

14 . The display module according to claim 11 , wherein the part of the support component located in the edge zone is provided with a third groove, and the at least one of the first surface and the second surface of the support component is provided with an opening of the third groove;
a minimum thickness of the part of the support component located in the edge zone is greater than a minimum thickness of the part of the support component located in the central zone.

15 . The display module according to claim 14 , wherein the minimum thickness of the part of the support component located in the edge zone is less than a minimum thickness of a part of the support component located in the second bending zone.

16 . The display module according to claim 14 , wherein, along the first direction, a length of the opening of the third groove ranges from 0.5 mm to 1 mm; and
a groove depth of the third groove is less than or equal to 0.1 mm.

17 . The display module according to claim 14 , wherein the at least a second groove comprises a plurality of second grooves, the first surface and the second surface of the support component are respectively provided with the opening of the second groove, and the first surface or the second surface of the support component is provided with the opening of the third groove.

18 . The display module according to claim 17 , wherein the second groove and the third groove located on a same side of the support component along the thickness direction have a same groove depth.

19 . The display module according to claim 14 , wherein both the opening of the at least a second groove and the opening of the third groove are located on the first surface, or, both the opening of the at least a second groove and the opening of the third groove are located on the second surface, and a groove depth of the second groove is greater than a groove depth of the third groove.

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