Abstract

An electronic device includes a foldable housing including a first housing structure and a second housing structure that are foldably connected with each other and that form a recess together and a flexible display located in the recess. The flexible display includes a first part located in the first area of the recess and having a first gap from the first portion of the second housing structure in the unfolded state, the first part including a first peripheral portion facing the first portion of the second housing structure and a second part located in the second area of the recess and having a second gap from the second portion of the second housing structure, the second part including a second peripheral portion facing the second portion of the second housing structure, in which the second gap is smaller than the first gap in the unfolded state.

First claim

What is claimed is:

1. A portable communication device comprising:
a housing including:
a hinge cover,
a first bracket, and
a second bracket configured to face the first bracket in a fully folded state;

a hinge accommodated in the housing, the hinge including:
a first hinge plate coupled with the first bracket and including a first opening formed therethrough, and
a second hinge plate coupled with the second bracket and including a second opening formed therethrough;

a flexible display accommodated in the housing, the flexible display including:
a first display portion disposed over the first bracket and the first hinge plate, and
a second display portion disposed over the second bracket and the second hinge plate; and

a flexible printed circuit board (FPCB) accommodated in the housing such that a first region of the FPCB is exposed through the first opening, a second region of the FPCB is exposed through the second opening, and a third region of the FPCB between the first region and the second region is disposed in the hinge cover as bended, the FPCB including a metal plate covering a portion of a rear surface of the first region such that, when viewed from a direction perpendicular to the flexible display, the metal plate is overlapped with a portion of a lateral periphery of the hinge cover when the housing is folded or unfolded.

2. The portable communication device of claim 1 , wherein the FPCB is attached to the first bracket via an adhesive layer formed on a portion of the metal plate.

3. The portable communication device of claim 1 , wherein the FPCB includes a second metal plate covering a portion of a rear surface of the second region, such that, when viewed from the direction, the second metal plate is overlapped with a portion of another lateral periphery of the hinge cover opposite to the lateral periphery when the housing is folded or unfolded.

4. The portable communication device of claim 1 , wherein:
the first hinge plate includes a third opening formed therethrough, and
the second hinge plate includes a fourth opening formed therethrough,
further comprising:
a second FPCB accommodated in the housing such that a first region of the second FPCB is exposed through the third opening, a second region of the second FPCB is exposed through the fourth opening, and a third region of the second FPCB between the first region and the second region of the second FPCB is disposed in the hinge cover as bended.

5. The portable communication device of claim 1 , wherein:
the portion of the lateral periphery of the hinge cover is protruded inwardly, and
the third region of the FPCB is disposed over the portion protruded inwardly.

6. The portable communication device of claim 1 , wherein the metal plate includes a SUS material.

7. The portable communication device of claim 1 , wherein the metal plate includes a first portion attached to the first bracket via an adhesive layer and a second portion extending from the first portion, and
wherein, when viewed from the direction perpendicular to the flexible display, the second portion of the metal plate overlaps with the portion of the lateral periphery of the hinge cover when the housing is folded or unfolded.

8. The portable communication device of claim 1 , wherein the metal plate is attached to the rear surface of the first region via an adhesive layer.

9. The portable communication device of claim 1 , wherein the metal plate is spaced apart from the portion of the lateral periphery of the hinge cover.

10. The portable communication device of claim 1 , wherein the metal plate does not cover a rear surface of the third region of the FPCB.

11. The portable communication device of claim 3 , wherein the second metal plate includes a first portion attached to the second bracket via an adhesive layer and a second portion extending from the first portion of the second metal plate, and
wherein, when viewed from the direction perpendicular to the flexible display, the second portion of the second metal plate overlaps with the portion of the other lateral periphery of the hinge cover when the housing is folded or unfolded.

12. The portable communication device of claim 3 , wherein the second metal plate is attached to the rear surface of the second region via an adhesive layer.

13. The portable communication device of claim 3 , wherein the second metal plate is spaced apart from the portion of the other lateral periphery of the hinge cover.

14. The portable communication device of claim 3 , wherein the second metal plate does not cover a rear surface of the third region of the FPCB.

15. A portable communication device comprising:
a foldable housing;
a hinge accommodated in the foldable housing, the hinge including a first hinge plate including a first opening formed therethrough, and a second hinge plate including a second opening formed therethrough; and
a flexible printed circuit board (FPCB) accommodated in the foldable housing such that a first region of the FPCB is exposed through in the first opening when viewing the first hinge plate from a direction perpendicular to a flexible display, a second region of the FPCB is exposed through in the second opening when viewing the first hinge plate from the direction perpendicular to the flexible display, and a third region of the FPCB between the first region and the second region is disposed in the hinge cover as bended, the FPCB including a metal plate covering a portion of a rear surface of the first region such that, when viewed from the direction perpendicular to the flexible display, the metal plate is overlapped with a portion of a lateral periphery of the hinge cover when the foldable housing is folded or unfolded.

16. The portable communication device of claim 15 , wherein the FPCB is attached to the foldable housing via an adhesive layer formed on a portion of the metal plate.

17. The portable communication device of claim 15 , wherein the FPCB includes a second metal plate covering a portion of a rear surface of the second region of the FPCB such that, when viewed from the direction, the second metal plate is overlapped with a portion of another lateral periphery of the hinge cover opposite to the lateral periphery when the foldable housing is folded or unfolded.

18. The portable communication device of claim 15 , wherein:
the first hinge plate includes a third opening formed therethrough, and
the second hinge plate includes a fourth opening formed therethrough,
further comprising:
a second FPCB accommodated in the foldable housing such that a first region of the second FPCB is exposed through the third opening, a second region of the second FPCB is exposed through the fourth opening, and a third region of the second FPCB between the first region and the second region of the second FPCB is disposed in the hinge cover as bended.

19. The portable communication device of claim 15 , wherein:
the portion of the lateral periphery of the hinge cover is protruded inwardly, and
the third region of the FPCB is disposed over the portion protruded inwardly.

20. The portable communication device of claim 15 , wherein the metal plate includes a SUS material.
