Abstract

A foldable display apparatus that is adjustable between a folded configuration and unfolded configuration includes a flexible display panel that is foldable; a case including a first case that supports a first side of the flexible display panel and a second case that supports a second side of the flexible display panel; a link member connecting the first case to the second; and a locking unit configured to prevent rotation of the first case and the second case in a folding direction when the foldable display apparatus is in the unfolded configuration.

First claim

What is claimed is:

1. A case assembly for a foldable display device, the case assembly comprising:
a first case;
a second case spaced apart from the first case;
a concave-convex type link member located between the first case and the second case; and
a sliding structure combined with the second case,
wherein the sliding structure is combined with the second case such that the sliding structure relatively moves with respect to the second case in a second direction opposite to a first direction in which the second case relatively moves with respect to the sliding structure,
wherein the second direction is towards the concave-convex type link member or away from the concave-convex type link member,
wherein the first case has a first side and a second side opposite to the first side, the concave-convex type link member has a third side and a fourth side opposite to the third side, and the second case has a fifth side and a sixth side opposite to the fifth side,
wherein, when the concave-convex type link member is unfolded, the first side of the first case, the third side of the concave-convex type link member, and the fifth side of the second case are at a same side and the second side of the first case, the fourth side of the concave-convex type link member, and the sixth side of the second case are at a same side,
wherein the sliding structure comprises a first guiding part,
wherein the second case comprises a second guiding part,
wherein for the concave-convex type link member to be unfolded or folded, the first guiding part and the second guiding part are combined with each other such that the sliding structure and the second case guide each other and relatively move in opposite directions to each other,
wherein when the concave-convex type link member is folded such that the second side of the first case and the sixth side of the second case are opposite to each other and the first side of the first case and the fifth side of the second case face each other, one of the first guiding part and the second guiding part is inserted in the other one of the first and second guiding parts,
wherein the sliding structure comprises a first portion expanding in parallel with the fifth side of the second case and a second portion connected to and expanding perpendicularly to the first portion; and
wherein the first guiding part is located at the second portion.

2. The case assembly of claim 1 , wherein when the concave-convex type link member is unfolded, the second side of the first case, the fourth side of the concave-convex type link member, and the sixth side of the second case are substantially planar.

3. The case assembly of claim 1 , wherein the concave-convex type link member comprises a plurality of connectors connected to each other, and
wherein a width of each of plurality of the connectors increases in a direction from the third side of the concave-convex type link member to the fourth side of the concave-convex type link member.

4. The case assembly of claim 3 , wherein when the concave-convex type link member is folded such that the second side of the first case and the sixth side of the second case are opposite to each other and the first side of the first case and the fifth side of the second case face each other, the concave-convex type link member has a substantially semicircular cross-section.

5. The case assembly of claim 1 , wherein when the concave-convex type link member is unfolded, the fourth side of the concave-convex type link member is relatively planar compared to the third side of the concave-convex type link member.

6. The case assembly of claim 1 , wherein at least a portion of the sliding structure is a rigid plate.

7. The case assembly of claim 1 , wherein when the concave-convex type link member is folded such that the second side of the first case and the sixth side of the second case are opposite to each other and the first side of the first case and the fifth side of the second case face each other, the first guiding part is inserted in the second guiding part.

8. The case assembly of claim 1 , wherein the concave-convex type link member comprises a metal.

9. The case assembly of claim 1 , wherein when the concave-convex type link member is unfolded, the concave-convex type link member and the sliding structure overlap with each other.

10. The case assembly of claim 9 , wherein when the concave-convex type link member is folded such that the second side of the first case and the sixth side of the second case are opposite to each other and the first side of the first case and the fifth side of the second case face each other, the concave-convex type link member and the sliding structure do not overlap with each other.

11. The case assembly of claim 1 , wherein for the concave-convex type link member to be unfolded, the sliding structure is relatively moved with respect to the second case in the second direction towards the concave-convex type link member.

12. The case assembly of claim 11 , wherein for the concave-convex type link member to be folded such that the second side of the first case and the sixth side of the second case are opposite to each other and the first side of the first case and the fifth side of the second case face each other, the sliding structure is relatively moved with respect to the second case in the second direction away from the concave-convex type link member.

13. The case assembly of claim 1 , wherein the sliding structure is rotatably connected to the first case.

14. A foldable display device, comprising:
a first case;
a second case spaced apart from the first case;
a concave-convex type link member located between the first case and the second case; and
a sliding structure combined with the second case,
wherein the sliding structure is combined with the second case such that the sliding structure relatively moves with respect to the second case in a second direction opposite to a first direction in which the second case relatively moves with respect to the sliding structure,
wherein the second direction is towards the concave-convex type link member or away from the concave-convex type link member,
wherein the first case has a first side and a second side opposite to the first side, the concave-convex type link member has a third side and a fourth side opposite to the third side, and the second case has a fifth side and a sixth side opposite to the fifth side,
wherein when the concave-convex type link member is unfolded, the first side of the first case, the third side of the concave-convex type link member, and the fifth side of the second case are on a same side and the second side of the first case, the fourth side of the concave-convex type link member, and the sixth side of the second case are on same side,
wherein the sliding structure comprises a first guiding part,
wherein the second case comprises a second guiding part,
wherein for the concave-convex type link member to be unfolded or folded, the first guiding part and the second guiding part are combined with each other such that the sliding structure and the second case guide each other and relatively move in opposite directions to each other,
wherein when the concave-convex type link member is folded such that the second side of the first case and the sixth side of the second case are opposite to each other and the first side of the first case and the fifth side of the second case face each other, one of the first guiding part and the second guiding part is inserted in the other one of the first and second guiding parts,
wherein a flexible display panel is continuously located on the second s
