Abstract

A device for bonding a window includes a chamber having an internal space, a display panel fixing unit in the chamber and including a first curved surface, the first curved surface being configured to attach to a flexible display panel, a window fixing unit in the chamber and including a second curved surface, at least part of the window fixing unit including an ultraviolet transmitting material, the second curved surface facing the first curved surface and being complementary with the first curved surface, and the second curved surface being configured to attach to a window, and an ultraviolet irradiating unit on the window fixing unit, the ultraviolet irradiating unit being configured to irradiate ultraviolet light through the window fixing unit toward the first curved surface of the display panel fixing unit.

First claim

What is claimed is:

1. A device for bonding a window, the device comprising:
a chamber having an internal space;
a display panel fixing unit in the chamber, the display panel fixing unit including a first curved surface to attach to a flexible display panel;
a window fixing unit in the chamber and including a second curved surface, at least part of the window fixing unit including an ultraviolet transmitting material, and the second curved surface facing the first curved surface and being complementary with the first curved surface to attach to a window; and
an ultraviolet irradiating unit on the window fixing unit, the ultraviolet irradiating unit being spaced apart from the second curved surface of the window fixing unit to irradiate ultraviolet light through the window fixing unit toward the first curved surface of the display panel fixing unit,
wherein the ultraviolet irradiating unit is on an opposite surface of the window fixing unit with respect to the second curved surface, the ultraviolet irradiating unit being continuous along the entire opposite surface.

2. The device for bonding a window of claim 1 , wherein the window fixing unit further comprises a moving unit to move the window fixing unit toward the display panel fixing unit.

3. The device for bonding a window of claim 1 , wherein each of the first curved surface and the second curved surface includes a flat surface in a center portion and curved edges extending from the flat surface.

4. The device for bonding a window of claim 3 , wherein the window fixing unit includes side parts formed of an ultraviolet transmitting material and a center part formed of an ultraviolet non-transmitting material, the center part defining the flat surface of the second curved surface, and the side parts defining the curved edges of the second curved surface.

5. The device for bonding a window of claim 1 , wherein the ultraviolet irradiating unit is directly on the opposite surface of the window fixing unit with respect to the second curved surface.

6. The device for bonding a window of claim 1 , wherein the ultraviolet irradiating unit is movable together with the window fixing unit.

7. The device for bonding a window of claim 2 , wherein the ultraviolet irradiating unit is between the window fixing unit and the moving unit.

8. The device for bonding a window of claim 1 , further comprising a discharging pump to provide vacuum conditions in the chamber.

9. The device for bonding a window of claim 1 , wherein at least a portion of the window fixing unit between the ultraviolet irradiating unit and the second curved surface includes the ultraviolet transmitting material.

10. The device for bonding a window of claim 9 , wherein the entirety of the portion of the window fixing unit is formed of the ultraviolet transmitting material.
