Abstract

An electronic device includes an electronic module, a display module including a first region overlapping the electronic module, and a second region not overlapping the electronic module, a window module disposed on the display module, and a coating layer disposed on at least one of a first outermost surface of the window module opposite to a second outermost surface of the window module facing the display module and a first outermost surface of the display module opposite to a second outermost surface of the display module facing the window module.

First claim

What is claimed is:

1 . An electronic device comprising:
an electronic module; a display module including a first region overlapping the electronic module, and a second region not overlapping the electronic module; a window module disposed on the display module; and a coating layer disposed on at least one of a first outermost surface of the window module opposite to a second outermost surface of the window module facing the display module and a first outermost surface of the display module opposite to a second outermost surface of the display module facing the window module.

2 . The electronic device of claim 1 , wherein the coating layer has an average thickness of about 10 nanometers to about 10000 nanometers.

3 . The electronic device of claim 1 , wherein the coating layer has a refractive index between a refractive index of an outermost layer of the window module including the first outermost surface and a refractive index of air, or between a refractive index of an outermost layer of the display module including the first outermost surface of the display module and the refractive index of air.

4 . The electronic device of claim 3 , wherein the coating layer has a refractive index of about 1.0 to about 1.6.

5 . The electronic device of claim 1 , wherein an entirety of the display module, the window module, and the coating layer which are stacked has a haze of about 4.5 percent or less.

6 . The electronic device of claim 1 , wherein the coating layer comprises an acryl-based resin, a siloxane-based resin, or a composite resin derived from a combination of the a 0 cryl-based resin and the siloxane-based resin.

7 . The electronic device of claim 1 , wherein the window module comprises a window, a protective layer disposed on a first surface of the window and including the first outermost surface opposite to the first surface of the window, and a window adhesive layer disposed on a second surface of the window opposite to the first surface of the window and facing the display module, and
the coating layer is disposed on at least one of the first outermost surface of the protective layer and the first outermost surface of the display module.

8 . The electronic device of claim 1 , wherein the display module comprises a display panel, and a first film disposed on a first surface of the display panel opposite to a second surface of the display panel facing the window module and including the first outermost surface of the display module, and
the coating layer is disposed on at least one of the first outermost surface of the window module and the first outermost surface of the first film.

9 . The electronic device of claim 8 , wherein the display module further comprises a second film disposed on the second surface of the display panel.

10 . The electronic device of claim 9 , wherein the first film and the second film are each a polymer film independently including polyethyleneterephthalate or polyimide.

11 . The electronic device of claim 1 , wherein the display module comprises a display panel, and a first film which is disposed on a first surface of the display panel opposite to a second surface of the display panel facing the window module and includes the first outermost surface of the display module,
the window module comprises a window, a protective layer which is disposed on a first surface of the window and includes the first outermost surface of the window module, and a window adhesive layer disposed on a second surface of the window opposite to the first surface of the window and facing the display module, and the coating layer comprises a first coating layer disposed on the first outermost surface of the first film and a second coating layer disposed on the first outermost of the protective layer.

12 . The electronic device of claim 11 , wherein the display module further comprises a second film disposed on the second surface of the display panel.

13 . The electronic device of claim 11 , wherein the window is a cover window including a glass material, and the protective layer comprises thermoplastic polyurethane, or polyethyleneterephthalate.

14 . An electronic device, which is divided into a folding region folded with respect to a folding axis extending in a direction, and a non-folding region adjacent to the folding region, the electronic device comprising:
an electronic module; a display panel including a first region overlapping the electronic module, and a second region not overlapping the electronic module; a window module disposed on a first surface of the display panel; a film disposed on a second surface of the display panel opposite to the first surface of the display panel; and a coating layer disposed on at least one of a first surface of the window module opposite to a second surface of the window module facing the display panel and a first surface of the film opposite to a second surface of the film facing the window module.

15 . The electronic device of claim 14 , wherein the coating layer has an average thickness of about 10 nanometers to about 10000 nanometers.

16 . The electronic device of claim 14 , wherein the coating layer has a refractive index of about 1.0 to about 1.6.

17 . The electronic device of claim 14 , an entirety of the display panel, the window module, the film, and the coating layer which are stacked has a haze of about 4.5 percent or less.

18 . An electronic device comprising:
an electronic module; a support module in which a through-hole is defined and which overlaps the electronic module; and a display member disposed on the support module, and including a display module, a window module disposed on the display module, and a coating layer disposed on at least one of a first outermost surface of the window module opposite to a second outermost surface of the window module facing the display module and a first outermost surface of the display module opposite to a second outermost surface of the display module facing the window module, wherein the display member has a haze of about 4.5 percent or less.

19 . The electronic device of claim 18 , wherein the display module comprises a display panel, and a film disposed on a first surface of the display panel opposite to a second surface of the display panel facing the window module,
the window module comprises a window including a glass material, a protective layer disposed on a first surface of the window, and a window adhesive layer disposed on a second surface of the window opposite to the first surface of the window and facing the display module, and the coating layer comprises a first coating layer disposed on a first surface of the protective layer opposite to a second surface of the protective layer facing the display module, and a second coating layer disposed on a first surface of the film opposite to a second surface of the film facing the window module.

20 . The electronic device of claim 19 , wherein the first coating layer and the second coating layer each have an average thickness of about 10 nanometers to about 10000 nanometers.
