Abstract

Disclosed is an electronic device. The electronic device according to an embodiment includes: a deformable display panel; a first window disposed on the deformable display panel; a first adhesive disposed between the deformable display panel and the first window; a second window disposed on the first window, the second window including a first surface, a second surface opposite the first surface, and a side surface disposed between the first surface and the second surface; a second adhesive disposed between the first window and the second window; and a shatterproof coating (SPC) provided on at least a part of the side surface of the second window and the first surface of the second window.

Claims (67)

1. An electronic device comprising:

a deformable display panel;

a first window disposed on the deformable display panel;

a first adhesive disposed between the deformable display panel and the first window;

a second window disposed on the first window, the second window including a first surface facing away from a surface of the deformable display panel from which light is emitted, a second surface opposite the first surface and facing the surface of the deformable display panel from which light is emitted, and a side surface disposed between the first surface and the second surface, wherein the first and second windows are both disposed on a same side of the deformable display panel;

a second adhesive disposed between the first window and the second window; and

a shatterproof coating (SPC) provided on at least a part of the side surface and the entire first surface of the second window.

2. The electronic device of claim 1 , wherein:

the second window includes a recess in the first surface; and

the shatterproof coating is provided on the first surface of the second window and fills the recess.

3. The electronic device of claim 2 , wherein:

the second window includes a folding region corresponding to a region in which the display panel is configured to be deformed;

the recess is provided in the folding region; and

the shatterproof coating is provided on at least an area of the side surface corresponding to the folding region.

4. The electronic device of claim 1 , wherein a shape of the side surface includes a curvature.

5. The electronic device of claim 1 , wherein a shape of the side surface includes a chamfered shape.

6. The electronic device of claim 1 , wherein:

the shatterproof coating is provided to surround the first surface of the second window, the second surface of the second window, and the side surface of the second window; and

the second adhesive is disposed between the first window and a portion of the shatterproof coating surrounding the second surface.

7. An electronic device comprising:

a deformable display panel;

a first window disposed on the deformable display panel;

a first adhesive disposed between the deformable display panel and the first window;

a second window disposed on the first window, the second window including a first surface, a second surface opposite the first surface, and a side surface disposed between the first surface and the second surface;

a second adhesive disposed between the first window and the second window;

a shatterproof coating (SPC) provided on at least a part of the side surface and the first surface; and

a strength reinforcement coating provided on a part of the side surface of the second window and the second surface of the second window,

wherein the shatterproof coating is provided on a remaining part of the side surface of the second window and the first surface of the second window, and

the second adhesive is disposed between the first window and a portion of the strength reinforcement coating provided on the second surface of the second window.

8. The electronic device of claim 1 , wherein the shatterproof coating is directly provided on at least a part of the side surface of the second window and the first surface of the second window without an adhesive.

9. The electronic device of claim 1 , wherein:

the second window includes glass; and

the first window includes at least one of polyimide (PI), polyethylene terephthalate (PET), polyurethane (PU), or cellulose triacetate (TAC).

10. The electronic device of claim 1 , wherein:

the deformable display panel is configured to be deformed based on folding of the electronic device; and

the shatterproof coating is provided on the first surface of the second window, and a portion of the side surface of the second window which is substantially perpendicular to an axis of the folding.

11. An electronic device comprising:

a deformable display panel;

a first window disposed on the deformable display panel, the first window including a first surface facing away from a surface of the deformable display panel from which light is emitted, a second surface opposite the first surface and facing the surface of the deformable display panel from which light is emitted, and a side surface disposed between the first surface and the second surface;

a first adhesive disposed between the deformable display panel and the first window;

a shatterproof coating (SPC) provided on at least a part of the side surface of the first window and the entire first surface of the first window;

a second window disposed on the first window, wherein the first and second windows are both disposed on a same side of the deformable display panel; and

a second adhesive disposed between the first window and the second window.

12. The electronic device of claim 11 , wherein:

the first window includes a recess in the first surface of the first window; and

the shatterproof coating is provided on the first surface of the first window and fills the recess.

13. The electronic device of claim 12 , wherein:

the first window includes a folding region corresponding to a region in which the display panel is configured to be deformed;

the recess is in the folding region; and

the shatterproof coating is provided on at least an area of the side surface of the first window corresponding to the folding region.

14. The electronic device of claim 11 , wherein the second adhesive is disposed between the second window and a portion of the shatterproof coating provided on the first surface of the first window.

15. The electronic device of claim 11 , wherein the shatterproof coating is directly provided on at least a part of the side surface of the first window and the first surface of the first window without an adhesive.

16. The electronic device of claim 11 , further comprising a hard coating provided on the second window,

wherein the electronic device further comprises at least one of:

an anti-fingerprint (AF) coating provided on the hard coating;

an anti-glare (AG) coating provided on the hard coating;

an anti-reflection (AR) coating provided on the hard coating; or

a low-refraction (LR) coating provided on the hard coating.

17. The electronic device of claim 11 , wherein:

the deformable display panel is configured to be deformed based on folding of the electronic device; and

the shatterproof coating is provided on the first surface of the first window, and a portion of the side surface of the first window which is substantially perpendicular to an axis of the folding.
