Abstract

A display apparatus includes a display module configured to display an image, and defining a folding area that is in-foldable about an imaginary folding axis, and a plurality of non-folding areas adjacent respective sides of the folding area in a plane, a support member having a plate shape under the display module, an adhesive member between the display module and the support member, and at least one first non-adhesive member overlapping with the folding area and located between the adhesive member and the support member.

Claims (41)

1. A display apparatus comprising:

a display module configured to display an image, and defining a folding area that is in-foldable about an imaginary folding axis, and a plurality of non-folding areas adjacent respective sides of the folding area in a plane;

a support member having a plate shape under the display module;

an adhesive member between the display module and the support member; and

at least one first non-adhesive member overlapping with the folding area and located between the adhesive member and the support member.

2. The display apparatus of claim 1 , wherein the first non-adhesive member reduces a coupling strength between the adhesive member and the support member.

3. The display apparatus of claim 1 , wherein the adhesive member has a single unitary body shape.

4. The display apparatus of claim 1 , wherein a rigidity of the support member is greater than a rigidity of the display module.

5. The display apparatus of claim 1 , wherein the first non-adhesive member comprises fluorine or titanium.

6. The display apparatus of claim 1 , wherein the first non-adhesive member is coupled to a top surface of the support member facing the adhesive member.

7. The display apparatus of claim 6 , wherein the first non-adhesive member is provided as a plurality of first non-adhesive members,

wherein the support member comprises:

a first support part coupled to the adhesive member and overlapping with a first non-folding area of the non-folding areas that is adjacent to one side of the folding area; and

a second support part spaced apart from the first support part, coupled to the adhesive member, and overlapping with a second non-folding area of the non-folding areas that is adjacent to another side of the folding area, and

wherein the first non-adhesive members are respectively on top surfaces of the first and second support parts that overlap with the folding area.

8. The display apparatus of claim 7 , wherein portions of the first and second support parts that overlap with the folding area are spaced apart from the adhesive member when the display module is folded.

9. The display apparatus of claim 6 , wherein the first non-adhesive member is coated on the top surface of the support member.

10. The display apparatus of claim 6 , wherein a recess is defined to be recessed downward from the top surface of the support member while overlapping with the folding area, and

wherein the first non-adhesive member fits in the recess.

11. The display apparatus of claim 6 , wherein the first non-adhesive member has a thickness of about 5 μm or less.

12. The display apparatus of claim 6 , further comprising a second non-adhesive member overlapping with the folding area, and coupled to a bottom surface of the adhesive member, which faces the support member.

13. The display apparatus of claim 6 , wherein the adhesive member comprises:

first portions overlapping with the non-folding areas; and

a second portion overlapping with the folding area and located between the first portions to connect the first portions, and

wherein an adhesive strength of the second portion is less than an adhesive strength of the first portions.

14. The display apparatus of claim 13 , wherein a hardness of the second portion is less than a hardness of the first portions.

15. The display apparatus of claim 13 , wherein a material of the second portion is different from a material of the first portions.

16. The display apparatus of claim 1 , wherein the first non-adhesive member is coupled to a bottom surface of the adhesive member, which faces the support member.

17. The display apparatus of claim 16 , wherein a recess is defined to be recessed upward from the bottom surface of the adhesive member overlapping with the folding area, and

wherein the first non-adhesive member fits in the recess.

18. A display apparatus comprising:

a display module configured to display an image, and defining a folding area that is in-foldable about an imaginary folding axis, a first non-folding area at one side of the folding area, and a second non-folding area at another side of the folding area;

a support member under the display module;

an adhesive member between the display module and the support member,

wherein the support member comprises:

a first support part coupled to the adhesive member and overlapping with the first non-folding area; and

a second support part spaced apart from the first support part, coupled to the adhesive member, and overlapping with the second non-folding area, and

wherein top surfaces of the first and second support parts overlapping with the folding area are not coupled to the adhesive member.

19. The display apparatus of claim 18 , further comprising first non-adhesive members between the adhesive member and the support member, overlapping with the folding area, and coupled to the top surfaces of the first and second support parts, respectively, or coupled to a bottom surface of the adhesive member.

20. The display apparatus of claim 19 , wherein the first non-adhesive members comprise fluorine or titanium.

21. The display apparatus of claim 18 , wherein the adhesive member comprises a single unitary body shape.
