Abstract

Jig assembly and method of manufacturing display device are provided. there is provided a jig assembly, including: an outer frame in which a hollow portion is defined; a support across the hollow portion; a movable cover coupled with the outer frame to expose the hollow portion; a fixed cover fixed to the outer frame; and a pressure bar disposed inside the outer frame and moving by a predetermined distance.

First claim

What is claimed is:

1. A jig assembly for manufacturing a display device, comprising:
an outer frame in which a hollow portion is defined;
a support disposed across the hollow portion;
a movable cover coupled with the outer frame;
a fixed cover directly fixed to the outer frame; and
a pressure bar disposed inside the outer frame, the pressure bar being movable toward a center of the hollow portion in a plan view.

2. The jig assembly of claim 1 ,
wherein the fixed cover overlaps the outer frame and the hollow portion in a plan view.

3. The jig assembly of claim 1 ,
wherein the movable cover is detachably coupled to the outer frame.

4. The jig assembly of claim 1 ,
wherein the pressure bar at least partially overlaps the fixed cover in a plan view.

5. The jig assembly of claim 1 , further comprising a moving screw penetrating the outer frame,
wherein the moving screw is engaged with the pressure bar to move the pressure bar.

6. The jig assembly of claim 5 ,
wherein the pressure bar includes a supporting portion engaged with the moving screw and a cushion portion disposed on the supporting portion and made of an elastic material.

7. The jig assembly of claim 1 ,
wherein the outer frame includes a first sub-outer frame and a second sub-outer frame, each extending in a y-axis direction and facing each other, and a third sub-outer frame and a fourth sub-outer frame, each extending in an x-axis direction and facing each other.

8. The jig assembly of claim 7 ,
wherein the movable cover includes a first sub-movable cover and a second sub-movable cover, and
the first sub-movable cover is detachably coupled with the third sub-outer frame, and the second sub-movable cover is detachably coupled with the first sub-outer frame.

9. The jig assembly of claim 8 ,
wherein the fixed cover includes a first sub-fixed cover and a second sub-fixed cover, and
the first sub-fixed cover is directly coupled with the fourth sub-outer frame, and the second sub-fixed cover is directly coupled with the second sub-outer frame.

10. The jig assembly of claim 8 , wherein the first sub-movable cover and the second sub-movable cover are connected to each other.

11. The jig assembly of claim 10 , wherein the first sub-movable cover and the second sub-movable cover are formed in one piece.

12. The jig assembly of claim 8 , wherein the first sub-movable cover and the second sub-movable cover have a bar shape and overlap the outer frame and the hollow portion.

13. The jig assembly of claim 7 , further comprising:
a moving pin penetrating the outer frame and connected with the pressure bar; and
a moving lever connected with the moving pin.

14. The jig assembly of claim 13 ,
wherein, when the moving lever rotates, the moving pin moves forward or backward to move the pressure bar.

15. The jig assembly of claim 1 ,
wherein the pressure bar includes a first pressure bar moving along a first direction and a second pressure bar moving along a second direction perpendicular to the first direction.
