Foldable display apparatus

1. A foldable display apparatus comprising:

a flexible display panel;

a case comprising a first case body, a second case body, and a hinge coupling the first and second case bodies;

a first support plate coupled to the first case body to support a first side of the flexible display panel; and

a second support plate coupled to the second case body to support a second side of the flexible display panel, wherein:

the first support plate disposed on the first case body, the first support plate comprising a first rotary support flexibly coupled to a first fixed support, the first fixed support comprising a first notch configured to receive a first protrusion of the first rotary support, and

the second support plate disposed on the second case body, the second support plate comprising a second rotary support flexibly coupled to a second fixed support, the second fixed support comprising a second notch configured to receive a second protrusion of the second rotary support.

2. The foldable display apparatus of claim 1 , wherein:

the first rotary support and the second rotary support are disposed adjacent to the hinge; and

the first fixed portion and the second fixed portion are disposed on opposing sides of hinge.

3. The foldable display apparatus of claim 2 , wherein the flexible display panel is fixed to the first fixed support and the second fixed support and moveable with respect to the first rotary support and the second rotary support.

4. The foldable display apparatus of claim 3 , wherein the first rotary support and the second rotary supports support a folding portion of the flexible display panel and are configured to rotate.

5. The foldable display apparatus of claim 1 , wherein the hinge comprises a curved case comprising a curved recess configured to accommodate the folding portion of the flexible display panel when the case is folded.

6. The foldable display apparatus of claim 5 , wherein the hinge further comprises a hinge pin and a hinge cap coupling the curved case to the first case body and the second case body.

7. The foldable display apparatus of claim 5 , wherein edges of the curved case are configured to support the first rotary support and the second rotary support when the case is unfolded, such that the first and second rotary supports, are in the same plane as the first and second fixed supports.

8. The foldable display apparatus of claim 7 , wherein the curved case has a semi-circular cross-section.

9. The foldable display apparatus of claim 1 , wherein the first case body and the second case body comprise stoppers configured to contact the first and second rotary supports when the case is in a folded position, and configured to be spaced apart from the first and second rotary supports when the case is in an unfolded position.

10. The foldable display apparatus of claim 9 , wherein the ends of the stoppers are configured to contact the first and second rotary supports, and are angled to correspond to a folding angle of the first and second rotary supports when the case is in a folded position.

11. The foldable display apparatus of claim 1 , wherein the first and second rotary supports are respectively hinged to the first and second fixed supports.

12. The foldable display apparatus of claim 1 , wherein the flexible display panel comprises an organic light-emitting diode display device.
