Abstract

A method for fabricating a protection member for a display apparatus includes; vertically standing a protection panel with respect to a ground surface, disposing a protection cushion to stand vertically with respect to the ground surface and to face the protection panel, and attaching the protection cushion to the protection panel while the protection panel and the protection cushion remain vertically standing with respect to the ground surface.

Claims

1. A method for fabricating a protection member for a display apparatus, comprising:

vertically standing a protection panel with respect to a ground surface;

disposing a protection cushion to stand vertically with respect to the ground surface and to face the protection panel; and

attaching the protection cushion to the protection panel while the protection panel and the protection cushion remain vertically standing with respect to the ground surface.

2. The method of claim 1, wherein the attaching of the protection cushion comprises:

disposing the protection cushion to be spaced apart from and to correspond to a cushion area of the protection panel; and

attaching the protection cushion proceeding from a first end thereof to a second end thereof, which is opposite to the first end.

3. The method of claim 2, wherein the attaching of the protection cushion comprises:

disposing a roller at the first end of the protection cushion; and

moving the roller to the second end from the first end to attach the protection cushion to the protection panel.

4. The method of claim 3, wherein a region of the protection cushion is inclined about 4 degrees with respect to the protection panel when the roller is disposed between the first and second ends.

5. The method of claim 1, wherein the standing of the protection panel comprises:

attaching the protection panel to a first vacuum pad using a vacuum; and

vertically standing the first vacuum pad with respect to the ground surface.

6. The method of claim 5, wherein the disposing of the protection cushion comprises:

attaching the protection cushion to a second vacuum pad using the vacuum;

vertically standing the second vacuum pad with respect to the ground surface; and

positioning the second vacuum pad to allow the first vacuum pad to face the second vacuum pad.

7. The method of claim 1, further comprising cleaning the protection panel using plasma prior to attaching the protection cushion.

8. A method for fabricating a protection member for a display apparatus, comprising:

vertically standing a protection panel with respect to a ground surface;

disposing a protection cushion to stand vertically with respect to a ground surface and to face the protection panel;

disposing the protection cushion to be spaced apart from and correspond to a cushion area of the protection panel;

disposing a roller at a first end of the protection cushion; and

moving the roller to a second end from the first end to attach the protection cushion to the protection panel, wherein the first and second ends are opposite to each other.

9. An apparatus for fabricating a protection member for a display apparatus, comprising:

a first vacuum pad which picks up a protection panel using a first vacuum and which vertically stands the protection panel with respect to a ground surface;

a second vacuum pad which picks up a protection cushion using a second vacuum and which vertically stands the protection cushion with respect to the ground surface; and

a roller which separates the protection cushion from the second vacuum pad and attaches the protection cushion to the protection panel, wherein the roller rotates about a rotation axis which is substantially vertical with respect to the ground surface.

10. The apparatus of claim 9, wherein the first vacuum pad is provided with a plurality of first vacuum holes to hold the protection panel using the first vacuum.

11. The apparatus of claim 9, wherein the second vacuum pad is provided with a plurality of second vacuum holes to hold the protection cushion using the second vacuum.

12. The apparatus of claim 9, wherein the first vacuum pad is spaced apart from the second vacuum pad while attaching the protection cushion to the protection panel.

13. A method for fabricating a display apparatus, comprising:

plasma-treating a first face of a polarizer to form a first pattern on the first face of the polarizer;

depositing an adhesive layer on the first pattern;

vertically standing the polarizer with respect to a ground surface;

vertically standing a display panel with respect to the ground surface; and

attaching the polarizer on which the adhesive layer is formed to the display panel while the polarizer and the display panel remain vertically standing.

14. The method of claim 13, wherein the first pattern is formed by a reduction reaction between the polarizer and the plasma applied to the first face of the polarizer.

15. The method of claim 13, further comprising plasma-treating a second face of the polarizer to form a second pattern on the second face of the polarizer, the second face facing the first face, prior to vertically standing the polarizer.

16. The method of claim 15, wherein the second pattern is formed by a reduction reaction between the polarizer and the plasma applied to the second face of the polarizer.

17. The method of claim 15, wherein the plasma-treating is performed under an atmospheric pressure.

18. The method of claim 15, further comprising combining a protection panel with the display panel after attaching the polarizer to the display panel.

19. The method of claim 18, further comprising attaching a protection cushion to the protection panel prior to combining the protection panel with the display panel,

wherein the protection cushion is disposed between the protection panel and the display panel.

20. The method of claim 19, wherein the combining of the protection panel with the display panel comprises:

vertically standing the display panel with respect to the ground surface;

vertically standing the protection panel with respect to the ground surface;

positioning display panel and the protection panel to face each other; and

attaching the protection cushion to the second face of the polarizer while the display panel and the protection panel remain vertically standing with respect to the ground surface.

21. The method of claim 20, wherein the protection panel is combined with the display panel in a vacuum chamber maintained at vacuum.

22. The method of claim 21, wherein a vacuum pressure of the vacuum chamber is in a range of about 10⁻

13 torr to about 500 torr.

23. The method of claim 15, wherein the first and second patterns are concavo-convex patterns.

24. An apparatus for fabricating a display apparatus, comprising:

a first vacuum pad which picks up a display panel using a first vacuum and vertically stands the display panel with respect to a ground surface;

a second vacuum pad which picks up a polarizer using a second vacuum and vertically stands the polarizer with respect to the ground surface; and

a roller which separates the polarizer from the second vacuum pad and attaches the polarizer to the display panel while being rotated, the roller having a rotation axis which is substantially vertical with respect to the ground surface.

25. The apparatus of claim 24, wherein the second vacuum pad picks up a protection panel to which a protection cushion is attached and vertically stands the protection panel with respect to the ground surface, and the roller separates the protection panel from the second vacuum pad and attaches the protection panel to the polarizer of the display panel with the protection cushion disposed between the protection panel and the polarizer.

26. A display apparatus comprising:

a display panel which displays an image using light provided from an exterior;

a polarizer which polarizes at least one of the light from the exterior and light exiting through the display panel, the polarizer being disposed on a face of the display panel and provided with a first pattern formed on a first face thereof adjacent to the display panel; and

an adhesive layer formed on the first face of the polarizer which attaches the polarizer to the display panel.

27. The display apparatus of claim 26, further comprising:

a protection panel disposed on the polarizer; and

a protection cushion attached to a face of the protection panel and disposed between the protection panel and the display panel which absorbs a shock applied to the display panel.

28. The display apparatus of claim 27, wherein the polarizer further comprises a second pattern formed on a second face facing the first face thereof, and the protection cushion is attached to the second face of the polarizer.

29. The display apparatus of claim 28, wherein the first and second patterns are concavo-convex patterns.
