Abstract

A jig for a cover window may include a lower jig and an upper jig on the lower jig. The lower jig may include a mounting portion, on which a cover window is configured to be disposed, and an exhausting portion adjacent to the mounting portion. The upper jig may include a cover unit, in which an opening exposing the mounting portion is defined, and a sidewall portion, coupled to the cover unit and enclosing the lower jig. The cover unit may be spaced apart from and overlapped with the exhausting portion.

First claim

What is claimed is:

1. A jig for a cover window, the jig comprising:
a lower jig comprising a mounting portion, on which a cover window is configured to be disposed, and an exhausting portion, adjacent to the mounting portion; and
an upper jig coupled with the lower jig, the upper jig comprising a cover unit, in which an opening exposing the mounting portion is defined, and a sidewall portion, coupled to the cover unit and enclosing the lower jig,
wherein the cover window comprises a front surface facing the mounting portion, a rear surface opposite the front surface, and a side surface between the front surface and the rear surface, and
wherein the mounting portion comprises a mounting surface facing the front surface of the cover window and a side surface facing the side surface of the cover,
wherein the cover unit is spaced apart from and extends over the exhausting portion and overlapping with the side surface of the mounting portion.

2. The jig of claim 1 , wherein the side surface of the mounting portion is aligned with a side surface of the cover unit, the side surface of the cover unit defining a boundary of the opening.

3. The jig of claim 2 , wherein a width of the side surface of the cover unit ranges from 0.5 mm to 1.5 mm.

4. The jig of claim 1 , wherein a height of the exhausting portion ranges from 3.0 mm to 8.0 mm.

5. The jig of claim 1 , wherein a width of the exhausting portion ranges from 1.0 mm to 3.0 mm.

6. The jig of claim 1 , wherein
at least a portion of the front surface of the cover window comprises a curved surface with a set curvature radius.

7. The jig of claim 6 , wherein the rear surface of the cover window comprises a curved surface having a same curvature radius as that of the front surface.

8. The jig of claim 6 , wherein the cover unit comprises a rear surface coupled to the side surface of the cover unit and facing the lower jig, and
a distance from an imaginary line, which extends from the rear surface of the cover unit, to the rear surface of the cover window ranges from 0.1 mm to 0.4 mm.

9. The jig of claim 8 , wherein the cover unit further comprises an inclined surface connecting the side surface of the cover unit to the rear surface of the cover unit and extending toward the exhausting portion.

10. The jig of claim 6 , wherein the cover window further comprises an inclined surface extending along an edge of the cover window, and
the inclined surface connects at least one of the front surface and rear surface of the cover window to the side surface thereof.

11. The jig of claim 1 , wherein the exhausting portion has a rectangular shape, when viewed in a sectional view.

12. The jig of claim 1 , wherein the exhausting portion has a closed line shape enclosing the mounting portion when viewed in a plan view.

13. A jig for a cover window, the jig comprising:
a lower jig comprising a mounting portion, on which a cover window is configured to be disposed, and an exhausting portion, adjacent to the mounting portion; and
an upper jig overlapping the exhausting portion, the upper jig comprising a cover unit, in which an opening exposing the mounting portion is defined, and a sidewall portion coupled to the cover unit and enclosing the lower jig,
wherein the cover window comprises a front surface facing the mounting portion, a rear surface opposite the front surface, and a side surface between the front surface and the rear surface, and
wherein the mounting portion comprises a mounting surface facing the front surface of the cover window and a side surface facing the side surface of the cover window,
wherein the cover unit is spaced apart from the lower jig and overlaying the exhausting portion and the side surface of the mounting portion.

14. The jig of claim 13 , wherein the side surface of the mounting portion is aligned with a side surface of the cover unit, the side surface of the cover unit defining a boundary of the opening.

15. The jig of claim 13 , wherein
at least a portion of the front surface of the cover window comprises a curved surface with a set curvature radius.

16. The jig of claim 15 , wherein the rear surface of the cover window comprises a curved surface having a same curvature radius as that of the front surface.

17. The jig of claim 13 , wherein the exhausting portion encloses the mounting portion and comprises a groove formed by removing a portion of the lower jig in a depth direction of the lower jig.

18. A jig for a cover window, the jig comprising:
a lower jig comprising a plurality of mounting portions spaced apart from each other, and a plurality of exhausting portions respectively adjacent to the mounting portions; and
an upper jig comprising a sidewall portion enclosing the lower jig and a cover unit laterally extending from the sidewall portion, the cover unit comprising a plurality of openings exposing the respective mounting portions,
wherein the exhausting portion is overlapped with the cover unit, and
wherein each of the plurality of mounting portions is formed integrally with a corresponding one of the plurality of exhausting portions, the exhausting portion comprising a groove formed by removing a portion of the lower jig in a depth direction of the lower jig.

19. The jig of claim 18 , wherein a side surface of the mounting portion is spaced apart from and aligned with a side surface of the cover unit, the side surface of the cover unit defining a boundary of the respective one of the plurality of openings.

20. The jig of claim 19 , wherein the plurality of openings of the cover unit are arranged in a grid shape.
