Abstract

A window glass forming apparatus according to one or more embodiments of the present invention includes a first mold configured to move along a first direction, a pressing member including a first end coupled to the first mold and configured to move along a second direction crossing the first direction, a second mold having a supporting surface configured to support a glass, and a curved surface extending from the supporting surface, and a third mold between the first mold and the second mold, the third mold being coupled to a second end of the pressing member and defining a guide groove configured to guide the pressing member along the curved surface.

First claim

What is claimed is:

1. A method of manufacturing an electronic device comprising a window, the method comprising:
arranging a glass on a supporting surface of a second mold, the second mold having a curved surface extending from the supporting surface;
moving a third mold located above the second mold, a first mold located above the third mold, and a pressing member located between the first mold and the third mold toward the second mold to support the glass, the third mold defining a guide groove corresponding to the curved surface of the second mold, and the pressing member comprising:
a first end coupled to the first mold; and
a second end coupled to the guide groove of the third mold; and

applying pressure to at least a portion of the glass by moving the first mold toward the second mold to move the pressing member along the guide groove of the third mold.

2. The method of claim 1 , comprising moving at least one of the second mold and the third mold along a first direction to reduce a distance between the second mold and the third mold.

3. The method of claim 1 , further comprising:
moving the pressing member along a supplementary guide groove defined in the first mold; and
applying pressure to at least a first portion of the glass such that the first portion of the glass contacts a first portion of the curved surface.

4. The method of claim 3 , comprising moving the first mold toward the second mold, the first end of the pressing member along the supplementary guide groove, and the second end of the pressing member along the guide groove,
wherein the first mold, the first end of the pressing member, and the second end of the pressing member are moved concurrently.

5. The method of claim 3 , further comprising applying pressure to a second portion of the glass such that the second portion of the glass contacts a second portion of the curved surface.

6. The method of claim 1 , further comprising heating the glass with a heating member in the first mold.

7. The method of claim 1 , wherein the curved surface has:
a first curved surface adjacent to the supporting surface; and
a second curved surface extending from the first curved surface, and comprising a portion of the curved surface that is farthest from an end portion of the supporting surface along a second direction.
