Abstract

Provided is a display window for a display apparatus, the display window including a base plate; a plurality of first coating patterns on an entire first surface of the base plate spaced from one another; and a plurality of second coating patterns on an entire second surface of the base plate spaced from one another and corresponding to the first coating patterns. A width of each of the first coating patterns is less than a width of a corresponding second coating pattern.

Claims

1. A display window for a display apparatus, the display window comprising:

a flexible base plate;

a plurality of first coating patterns on an entire first surface of the flexible base plate, the first coating patterns being spaced from one another in a first direction; and

a plurality of second coating patterns on an entire second surface of the flexible base plate, the second coating patterns being spaced from one another in the first direction, at least one of each of the first coating patterns is located within an outer periphery of a corresponding single one of the second coating patterns in the first direction, such that the entirety of each of the first coating patterns is located within an outer periphery of a corresponding single one of the second coating patterns in the first direction.

2. The display window as claimed in claim 1, wherein the entirety of a single first coating pattern is located within the outer periphery of corresponding single one of the second coating patterns in the first direction.

3. The display window as claimed in claim 1, wherein the entirety of more than one first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction.

4. The display window as claimed in claim 1, wherein the entirety of n first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction in a central portion of the base plate, and the entirety of k first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction in a peripheral portion of the base plate, n and k each denoting a natural number and n>

k.

5. The display window as claimed in claim 1, wherein

the base plate has a rectangular shape including a long axis extending in the first direction and a short axis extending in a second direction, the second direction being orthogonal to the first direction, and the second coating patterns extend along the short axis.

6. The display window as claimed in claim 5, wherein the entirety of n first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction in a central portion of the base plate, and the entirety of k first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction in a peripheral portion of the base plate, with respect to the long axis of the base plate, n and k each denoting a natural number and n>

k.

7. The display window as claimed in claim 1, wherein the second surface of the base plate is a surface facing a display panel.

8. The display window as claimed in claim 1, wherein a hardness of the first coating patterns and a hardness of the second coating patterns are each greater than a hardness of the base plate.

18. The display window as claimed in claim 1, wherein:

the first coating patterns extend in a second direction, the second direction being orthogonal to the first direction;

the second coating patterns extend in the second direction, and the entirety of each of the first coating patterns is located within an outer periphery of one of the second coating patterns in the second direction.

9. A display apparatus, comprising:

a display panel including display devices; and

a display window on the display panel, the display window including;

a flexible base plate;

a plurality of first coating patterns on an entire first surface of the flexible base plate, the first coating patterns being spaced from one another in a first direction; and

a plurality of second coating patterns on an entire second surface of the flexible base plate, the second coating patterns being spaced from one another in the first direction,

at least one of each of the first coating patterns is located within an outer periphery of a corresponding single one of the second coating patterns in the first direction such that the entirety of each of the first coating patterns is located within an outer periphery of a corresponding single one of the second coating patterns in the first direction, and the second surface of the flexible base plate facing the display panel.

10. The display apparatus as claimed in claim 9, further comprising a touch panel between the display panel and the display window.

11. The display apparatus as claimed in claim 9, wherein the entirety of a single first coating pattern is located within the outer periphery of corresponding single one of the second coating patterns in the first direction.

12. The display apparatus as claimed in claim 9, wherein the entirety of more than one first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction.

13. The display apparatus as claimed in claim 9, wherein the entirety of n first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction in a central portion of the base plate, and the entirety of k first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction in a peripheral portion of the base plate, n and k each denoting a natural number and n>

k.

14. The display apparatus as claimed in claim 9, wherein

the base plate has a rectangular shape including a long axis extending in the first direction and a short axis extending in a second direction, the second direction being orthogonal to the first direction, and the second coating patterns extend along the short axis.

15. The display apparatus as claimed in claim 14, wherein the entirety of n first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction in a central portion of the base plate, and the entirety of k first coating patterns is located within the outer periphery of corresponding single one of the second coating patterns in the first direction in a peripheral portion of the base plate, with respect to the long axis of the base plate, n and k each denoting a natural number and n>

k.

16. The display apparatus as claimed in claim 9, wherein a hardness of the first coating patterns and a hardness of the second coating patterns are each greater than a hardness of the base plate.

17. The display apparatus as claimed in claim 9, wherein:

the first coating patterns extend in a second direction, the second direction being orthogonal to the first direction;

the second coating patterns extend in the second direction, and the entirety of each of the first coating patterns is located within an outer periphery of one of the second coating patterns in the second direction.
