Abstract

A flexible display panel including: a flexible substrate including a first region, second regions that extend from the first region and that have a curved surface, and a third region folded towards the second regions; a first display region in the first region of the flexible substrate; a second display region in the second regions of the flexible substrate; a plurality of non-display regions outside the first display region or the second display regions, wherein at least one of the plurality of non-display regions is in the third region of the flexible substrate; and an encapsulation member for encapsulating the first display region and the second display regions.

Claims (36)

1. A display apparatus comprising:

a flexible display panel comprising:

a first region comprising a first display region; and

a second region extending from the first region and facing a different direction from the first region, the second region comprising a second display region and a first non-display region;

a support member for maintaining a shape of the flexible display panel;

an encapsulation thin layer on the flexible display panel and covering the first display region and the second display region;

a touch layer on the encapsulation thin layer and comprising touch regions, the touch regions overlapping the first display region and the second display region; and

at least one light-emitting diode,

wherein the at least one light-emitting diode is located in the first display region or the second display region.

2. The display apparatus of claim 1 , further comprising a transparent protection window located on the touch layer, the transparent protection window overlapping the first display region and the second display region.

3. The display apparatus of claim 1 , wherein the second region has a curved surface.

4. The display apparatus of claim 3 , wherein the curved surface of the second region is configured to display an image while the curved surface remains curved.

5. The display apparatus of claim 1 , wherein each of the first display region and the second display region is configured to display an image when the second display region faces a different direction from the first display region.

6. The display apparatus of claim 1 , wherein the encapsulation thin layer comprises at least one of an inorganic layer or an organic layer.

7. The display apparatus of claim 1 , wherein the touch layer further comprises touch wirings outside the touch regions.

8. The display apparatus of claim 1 , wherein the second display region is connected with the first display region.

9. The display apparatus of claim 8 , wherein the second display region is disposed between the first display region and the first non-display region.

10. The display apparatus of claim 1 , further comprising a second non-display region extending from the first non-display region, the second non-display region facing a different direction from the first non-display region.

11. A display apparatus comprising:

a flexible display panel comprising:

a first display region; and

a second display region extending from the first display region and facing a different direction from the first display region;

a support member for maintaining a shape of the flexible display panel;

an encapsulation thin layer on the flexible display panel and covering the first display region and the second display region;

a touch layer on the encapsulation thin layer and comprising touch regions, the touch regions overlapping the first display region and the second display region;

a transparent protection window located on the touch layer, the transparent protection window overlapping the first display region and the second display region; and

at least one light-emitting diode, wherein the at least one light-emitting diode is located in the first display region or the second display region, and

wherein the touch layer is located between the transparent protection window and the encapsulation thin layer.

12. The display apparatus of claim 11 , further comprising an adhesive between the transparent protection window and the flexible display panel.

13. The display apparatus of claim 11 , wherein the touch layer further comprises touch wirings outside the touch regions.

14. The display apparatus of claim 11 , wherein the flexible display panel further comprise non-display regions outside the first and second display regions.

15. The display apparatus of claim 14 , further comprising at least one circuit unit disposed in the non-display regions, the at least one circuit unit configured to transmit a signal to the first and second display regions.

16. The display apparatus of claim 15 , wherein the touch layer further comprises touch wirings outside the touch regions, and

wherein the touch wirings overlap the at least one circuit unit.

17. The display apparatus of claim 11 , wherein the second display region has a curved surface.

18. The display apparatus of claim 11 , wherein the encapsulation thin layer comprises at least one of an inorganic layer or an organic layer.
