Abstract

An apparatus for manufacturing a display apparatus includes a deforming unit which deforms a shape of a cover window by pressing the cover window, where the deforming unit includes a first mold, on which the cover window is accommodated; a sleeve, which is spaced apart from the first mold and moves linearly to the first mold; a second mold, which is inserted into the sleeve to move linearly to the first mold to deform a portion of the cover window; and a pressing plate, which presses the sleeve and the second mold to the first mold.

First claim

What is claimed is:

1. A method of manufacturing a display apparatus, the method comprising:
accommodating a cover window on a first mold;
pre-heating the cover window;
arranging a sleeve and a second mold on the cover window on the first mold, wherein the second mold comprises a first sub-mold and a second sub-mold; and
molding the cover window by pressing the first sub-mold, the second sub-mold and the sleeve to the first mold,
wherein the molding the cover window by pressing the first sub-mold, the second sub-mold and the sleeve comprises moving a single pressing plate to contact the first sub-mold, the second sub-mold and the sleeve, and
wherein the first sub-mold, the second sub-mold and the sleeve are disposed in a way such that the single pressing plate contacts the first sub-mold, the second sub-mold and the sleeve sequentially in the order of the second sub-mold, the first sub-mold and the sleeve when the single pressing plate moves to the first sub-mold, the second sub-mold and the sleeve.

2. The method of claim 1 , further comprising:
transferring the first mold on which the cover window is accommodated.

3. The method of claim 1 , wherein the molding the cover window by pressing the sleeve and the second mold comprises heating the cover window.

4. The method of claim 1 , further comprising:
cooling the cover window.

5. The method of claim 4 , wherein the cooling the cover window comprises arranging a pressing plate comprising a cooler on the sleeve and the second mold.

6. The method of claim 1 , wherein the second mold is inserted into the sleeve and moves linearly.

7. The method of claim 1 , wherein
the sleeve contacts a flat portion of the cover window and supports the cover window, and
the second mold contacts a portion of the cover window to be deformed.

8. The method of claim 7 , wherein
the first sub-mold and the second sub-mold are disposed to move linearly to the portion of the cover window to be deformed.

9. The method of claim 1 , wherein a width of the second mold in a lengthwise direction of the sleeve is inconstant.
