Abstract

A manufacturing apparatus of a flexible display device, including: a main chamber in which a display device is mounted; an auxiliary chamber configured to inject a first pressing material having fluidity into the main chamber; and a driving portion configured to rotate the main chamber.

First claim

What is claimed is:

1. A manufacturing apparatus of a flexible display device, comprising:
a main chamber configured to mount a display device;
an auxiliary chamber configured to inject a first pressing material having fluidity into the main chamber; and
a driving portion configured to rotate the main chamber.

2. The manufacturing apparatus of the flexible display device of claim 1 , wherein
the first pressing material comprises at least one of a liquid and a metal ball.

3. The manufacturing apparatus of the flexible display device of claim 2 , wherein:
the first pressing material comprises the liquid and the metal ball;
a specific gravity of the liquid is 0.8 to 1.0; and
a specific gravity of the metal ball is equal to or greater than 2.5.

4. The manufacturing apparatus of the flexible display device of claim 2 , wherein
the liquid comprises at least one of mercury, a lubricating oil, and water.

5. The manufacturing apparatus of the flexible display device of claim 1 , wherein the driving portion is configured to rotate the main chamber at a first speed or a second speed.

6. The manufacturing apparatus of the flexible display device of claim 5 , wherein
the second speed is greater than the first speed.

7. The manufacturing apparatus of the flexible display device of claim 5 , wherein:
when the main chamber rotates at the first speed, the first pressing material is positioned at a central portion of the main chamber; and
when the main chamber rotates at the second speed, the first pressing material is positioned at a peripheral portion of the main chamber.

8. The manufacturing apparatus of the flexible display device of claim 1 , further comprising:
an inlet configured to inject the first pressing material into the main chamber; and
an outlet configured to remove the first pressing material from the main chamber.

9. The manufacturing apparatus of the flexible display device of claim 1 , wherein
the manufacturing apparatus of the flexible display device comprises a plurality of main chambers.

10. A method of manufacturing a flexible display device, comprising:
mounting a display panel and a window in a main chamber in a provisionally combined state;
injecting a first pressing material having fluidity into the main chamber;
rotating the main chamber at a first speed; and
rotating the main chamber at a second speed.

11. The method of claim 10 , wherein
the first pressing material includes the liquid and the metal ball,
a specific gravity of the liquid is 0.8 to 1.0, and
a specific gravity of the metal ball is equal to or greater than 2.5.

12. The method of claim 10 , wherein the first speed is slower than the second speed.

13. The method of claim 10 , wherein each of the display panel and the window comprises:
a flat portion; and
a lateral portion forming a predetermined angle with the flat portion.

14. The method of claim 13 , wherein, in the rotating of the main chamber at the first speed, the first pressing material overlaps the flat portion of the display panel and the flat portion of the window.

15. The method of claim 13 , wherein, in the rotating of the main chamber at the second speed, the first pressing material is positioned to be adjacent to the respective lateral portions.

16. The method of claim 10 , wherein the first pressing material moves from the flat portions of the display panel and the window to the lateral portions thereof.

17. The method of claim 10 , further comprising, after the first pressing material is mounted, applying pressure to the inside of the main chamber.

18. The method of claim 10 , further comprising removing the first pressing material from the main chamber.

19. A method of manufacturing a flexible display device, comprising:
mounting a display panel and a window in a main chamber in a provisionally combined state;
injecting a first pressing material having fluidity into the main chamber; and
rotating the main chamber at a first speed.

20. The method of claim 19 , wherein the first pressing material comprises at least one of a liquid and a metal ball.
