Abstract

A display apparatus includes: a display panel including a display portion and a plurality of connection portions connected to the display portion and extending in different directions; and a cover window disposed on the display panel. The cover window includes: a first member defining a plurality of opening patterns therein; and a second member disposed in the plurality of opening patterns, and a modulus of the first member is greater than a modulus of the second member.

First claim

What is claimed is:

1 . A display apparatus comprising:
a display panel comprising a display portion and a plurality of connection portions connected to the display portion and extending in different directions; and a cover window disposed on the display panel, wherein the cover window comprises:
a first member defining a plurality of opening patterns therein; and
a second member disposed in the plurality of opening patterns, and
a modulus of the first member is greater than a modulus of the second member.

2 . The display apparatus of claim 1 , wherein each of the plurality of opening patterns comprises a first opening extending in a first direction and a second opening formed in a first end of the first opening.

3 . The display apparatus of claim 2 , wherein each of the plurality of opening patterns further comprises a third opening formed in a second end of the first opening opposite to the first end of the first opening.

4 . The display apparatus of claim 3 , wherein the plurality of opening patterns are arranged parallel to the first direction, which is a longitudinal direction of the first opening.

5 . The display apparatus of claim 4 , wherein an interval between the plurality of opening patterns in the first direction is less than a length of the first opening in the first direction.

6 . The display apparatus of claim 4 , wherein a length of the second opening in the first direction is less than a length of the first opening in the first direction.

7 . The display apparatus of claim 4 , wherein a length of the third opening in the first direction is less than a length of the first opening in the first direction.

8 . The display apparatus of claim 4 , wherein, in a second direction perpendicular to the first direction, a width of the first opening is less than each of a width of the second opening and a width of the third opening.

9 . The display apparatus of claim 4 , wherein the plurality of opening patterns comprise a first opening pattern, a second opening pattern, and a third opening pattern, which are sequentially arranged and apart from one another in a second direction perpendicular to the first direction, and
a second opening of the first opening pattern and a second opening of the third opening pattern are on a virtual straight line in the second direction, and a first opening of the second opening pattern is between the second opening of the first opening pattern and the second opening of the third opening pattern.

10 . The display apparatus of claim 4 , wherein each of the second opening and the third opening has a circular shape.

11 . The display apparatus of claim 4 , wherein the second opening and the third opening have a same size.

12 . The display apparatus of claim 1 , wherein a modulus of the first member is greater than 1 gigapascal (GPa) and less than 10 GPa.

13 . The display apparatus of claim 1 , wherein a modulus of the second member is greater than 0 GPa and less than 0.1 GPa.

14 . The display apparatus of claim 1 , wherein a difference in a refractive index between the first member and the second member is 0 to 3/1000.

15 . The display apparatus of claim 1 , wherein the first member comprises glass, polyethylene terephthalate (PET), or transparent polyimide (PI).

16 . The display apparatus of claim 1 , wherein the second member comprises thermoplastic polyurethane (TPU) or polydimethylsiloxane (PDMS).

17 . The display apparatus of claim 1 , wherein each of the plurality of opening patterns comprise a plurality of first openings each having a common end converging at a center point of a corresponding opening pattern, and a plurality of second openings formed in opposite ends opposite to the common end of the plurality of first openings.

18 . The display apparatus of claim 17 , wherein an angle between the plurality of first openings is 120 degrees (°).

19 . The display apparatus of claim 17 , wherein each of the plurality of second openings is formed to point toward a center point of another opening pattern closest to each of the plurality of second openings.

20 . A cover window for a display panel disposed on the display panel, the cover window comprising:
a first member defining a plurality of opening patterns therein; and a second member disposed in the plurality of opening patterns, wherein a modulus of the first member is greater than a modulus of the second member.
