Abstract

An apparatus for manufacturing a display device includes a first jig including a first side, the first side having a concave groove for receiving a cover window, wherein the cover window includes a first planar portion, a first curved portion and a second curved portion, wherein the first and second curved portions are disposed at opposite ends of the first planar portion in a first direction, a second jig including a planar side for receiving a display panel, wherein when the second jig is moved in a second direction crossing the first direction with the display panel on the planar side, the display panel is disposed between the first and second curved portions of the cover window, and a pair of third jigs for supporting the first and second curved portions of the cover window.

First claim

What is claimed is:

1. An apparatus for manufacturing a display device, comprising:
a first jig including a first side, the first side having a concave groove for receiving a cover window, wherein the cover window includes a first planar portion, a first curved portion and a second curved portion, wherein the first and second curved portions are disposed at opposite ends of the first planar portion in a first direction;
a second jig including a planar side for receiving a display panel and provided to horizontally move in a second direction crossing the first direction, wherein when the second jig is moved in the second direction with the display panel on the planar side, the display panel is disposed between the first and second curved portions of the cover window; and
a pair of third jigs for supporting the first and second curved portions of the cover window.

2. The apparatus of claim 1 , wherein the second jig includes:
a body including the planar side; and
a first side portion and a second side portion disposed at opposite ends of the body in the first direction, wherein each of the first and second side portions is convex,
wherein a radius of curvature of the first side portion is equal to or less than a radius of curvature of the first curved portion of the cover window, and a radius of curvature of the second side portion is equal to or less than a radius of curvature of the second curved portion of the cover window.

3. The apparatus of claim 2 , wherein when the second jig is moved toward the first jig in a third direction that crosses the first direction and the second direction, the first planar portion of the cover window is bonded to the display panel.

4. The apparatus of claim 3 , wherein the first side portion of the second jig protrudes away from the body in the first direction to bond the display panel to the first curved portion of the cover window, and the second side portion of the second jig protrudes away from the body in a direction opposite to the first direction to bond the display panel to the second curved portion of the cover window.

5. The apparatus of claim 3 , wherein the second jig is movable in the first direction and in a direction opposite to the first direction to bond opposite ends of the display panel to opposite ends of the cover window, respectively.

6. The apparatus of claim 2 , wherein the first side portion of the body includes a first elastic member; and the second side portion of the body includes a second elastic member.

7. The apparatus of claim 2 , further comprising a first clamp for bending a first end of the display panel against the first side portion of the second jig and to fix the first end of the display panel to the first side portion of the second jig, and a second clamp for bending a second end of the display panel against the second side portion of the second jig and to fix the second end of the display panel to the second side portion of the second jig.

8. The apparatus of claim 1 , further comprising a fourth jig that is movable in the second direction, and includes a side portion having a shape that corresponds to the first curved portion of the cover window.

9. An apparatus for manufacturing a display device, comprising:
a first support member having a first flat portion, a first concave portion disposed on a first side of the first flat portion and a second concave portion disposed on a second side of the first flat portion, wherein the first and second sides of the first flat portion face each other in a first direction, wherein the first and second concave portions extend in a second direction crossing the first direction;
a second support member for supporting a cover window and a flexible display panel, wherein the second support member includes a second flat portion, a first convex portion disposed on a first side of the second flat portion and a second convex portion disposed on a second side of the second flat portion, wherein the first and second sides of the second flat portion face each other in the first direction, wherein the cover window has a third flat portion and a pair of third curved portions on opposite sides of the third flat portion; and a pair of third support members for supporting the first and second curved portions of the cover window,
wherein the second support member is disposed between the first support member and the pair of third support members, wherein the cover window and the flexible display panel are disposed between the second support member and the first support member, and between the second support member and the pair of third support members, and
wherein the second support member is configured to move in a third direction crossing the first and second directions to attach a first portion of the flexible display panel to the third flat portion, and to move in the first direction and in a direction opposite to the first direction to attach a second portion of the flexible display panel to the pair of third curved portions.
