Abstract

An electronic device including a foldable housing including a first housing, a second housing, and a connection structure; a flexible display; a first plate including at least a portion disposed on a lower end of a first area of the display and a first periphery; a second plate including at least a portion disposed on a lower end of a second area of the display, and a second periphery; and a protection layer. When the electronic device is in an unfolded state, the first periphery and the second periphery are configured to be in contact with the display. When the electronic device pivots from the unfolded state to a folded state, the first periphery and the second periphery are configured to be spaced apart from the display, and the protection layer is configured to cover an area of the display exposed between the first periphery and the second periphery.

First claim

What is claimed is:

1. A portable communication device comprising:
a housing including a first housing portion and a second housing portion and foldable with respect to a folding axis;
a flexible display including a first display area accommodated in the first housing portion, a second display area accommodated in the second housing portion, and a folding area located between the first display area and the second display area;
a hinge assembly coupled with the first housing portion and the second housing portion, the hinge assembly including:
a first hinge plate disposed between the first housing portion and the flexible display and configured to support part of the first display area;
a second hinge plate disposed between the second housing portion and the flexible display and configured to support part of the second display area;
a hinge cover disposed between the first housing portion and the second housing portion such that the hinge cover is substantially exposed to an outside of the portable communication device when the housing is folded and substantially hidden by the first housing portion and the second housing portion when the housing is unfolded; and
a hinge module to which each of the first housing portion and the second housing portion is pivotably connected, the hinge module configured to be substantially surrounded by the first hinge plate, the second hinge plate and the hinge cover when the housing is unfolded; and

a protection layer extended over the first hinge plate, the second hinge plate and the hinge module, the protection layer including a first area fixed at the first hinge plate and a second area slidable with respect to the second hinge plate according to the housing being folded.

2. The portable communication device of claim 1 , wherein the protection layer has a first width greater than a second width of the hinge cover.

3. The portable communication device of claim 1 , wherein the hinge assembly includes:
a bonding layer disposed between the first area of the protection layer and the first hinge plate such that the first area of the protection layer is attached to the first hinge plate via the bonding layer.

4. The portable communication device of claim 3 , wherein the hinge assembly includes:
a friction prevention member disposed between the bonding layer and the first hinge plate and configured to reduce a friction between the protection layer and the first hinge plate.

5. The portable communication device of claim 1 , wherein the folding area of the flexible display is bent when a space between the first hinge plate and the second hinge plate increases according to the housing being folded.

6. The portable communication device of claim 5 , wherein a part of the protection layer deforms into a shape corresponding to the folding area of the flexible display when the space between the first hinge plate and the second hinge plate increases according to the housing being folded.

7. The portable communication device of claim 1 , wherein the protection layer stretches when a space between the first hinge plate and the second hinge plate increases according to the housing being folded.

8. The portable communication device of claim 1 , wherein the protection layer contracts when a space between the first hinge plate and the second hinge plate decreases according to the housing being unfolded.

9. The portable communication device of claim 1 , wherein the first display area and the second display area are disposed to substantially face each other when the portable communication device is fully folded.

10. The portable communication device of claim 1 , wherein the first hinge plate and the second hinge plate are disposed to substantially face each other when the portable communication device is fully folded.

11. The portable communication device of claim 1 , wherein the first display area and the second display area are disposed to face in a substantially same direction when the portable communication device is unfolded.

12. The portable communication device of claim 1 , wherein the first hinge plate and the second hinge plate are disposed to face in a substantially same direction when the portable communication device is unfolded.

13. The portable communication device of claim 1 , wherein the second area of the protection layer slides in a direction toward the hinge cover when a space between the first hinge plate and the second hinge plate increases according to the housing being folded.

14. The portable communication device of claim 1 , wherein the folding area is substantially coplanar with the first display area and the second display area when the portable communication device is unfolded.

15. A portable communication device comprising:
a housing including a first housing portion and a second housing portion and foldable with respect to a folding axis;
a flexible display including a first display area accommodated in the first housing portion, a second display area accommodated in the second housing portion, and a folding area located between the first display area and the second display area;
a hinge assembly coupled with the first housing portion and the second housing portion, the hinge assembly including:
a first hinge plate disposed between the first housing portion and the flexible display and having a first side periphery extended along the folding axis;
a second hinge plate disposed between the second housing portion and the flexible display and having a second side periphery extended along the folding axis of the housing and adjacent to the first side periphery;
a hinge cover disposed between the first housing portion and the second housing portion such that the hinge cover is substantially exposed to an outside of portable communication device when the housing is folded and substantially hidden by the first housing portion and the second housing portion when the housing is unfolded; and
a hinge module to which each of the first housing portion and the second housing portion is pivotably connected, the hinge module configured to be substantially surrounded by the first hinge plate, the second hinge plate and the hinge cover when the housing is unfolded; and

a protection layer extended over the first hinge plate, the second hinge plate and the hinge module, and including a first area fixed at the first hinge plate and a second area slidable with respect to the second hinge plate according to a state of the housing being transitioned from an unfolded state to a folded state.

16. The portable communication device of claim 15 , wherein the protection layer has a first width greater than a second width of the hinge cover.

17. The portable communication device of claim 15 , wherein the hinge assembly includes:
a bonding layer disposed between the protection layer and the first hinge plate such that the protection layer is attached to the first hinge plate via the bonding layer.

18. The portable communication device of claim 17 , wherein the hinge assembly includes:
a friction prevention member disposed between the bonding layer and the first hinge plate and configured to reduce a friction between the protection layer and the first hinge plate.

19. The portable communication device of claim 15 , wherein the folding area of the flexible display is bent when a space between the first hinge plate and the second hinge plate increases according to the housing being transitioned from the unfolded state to the folded state.

20. A portable communication device comprising:
a hou
