Abstract

A flexible display panel and a display apparatus including the flexible display panel are disclosed. The flexible display panel includes an encapsulated panel, a first protective film on one side of the encapsulated panel, and a second protective film on another side of the encapsulated panel. The encapsulated panel includes a flexible panel and a flexible encapsulation member on the flexible panel. The flexible panel includes a first region on a first plane and that includes a display region, and a second region on a second plane that is bent with respect to the first plane and that includes a non-display region. The flexible encapsulation member encapsulates the display region. The display apparatus also includes a support unit for maintaining a shape of the flexible panel.

Claims (42)

1. A flexible display panel having a display region and a first non-display region on a first plane, a second non-display region on a second plane that is bent with respect to the first plane, and an extension of the display region into a border region between the display region on the first plane and the second non-display region on the second plane, the flexible display panel comprising:

a first protective film;

an encapsulated panel on the first protective film and comprising:

a flexible substrate;

a layer on the flexible substrate and in each of the display region, the display region extension, the first non-display region, and the second non-display region; and

a flexible encapsulation member on the flexible substrate to encapsulate the layer therebetween; and

a second protective film on the encapsulated panel.

2. The flexible display panel of claim 1 , wherein the first protective film and the second protective film completely cover the display region, the display region extension, the first non-display region, and the second non-display region.

3. The flexible display panel of claim 1 ,

wherein the display region is configured to display in a first direction in which the first plane is facing, and

wherein the second non-display region is not facing the first direction.

4. The flexible display panel of claim 1 , wherein an area ratio of the second non-display region to the display region as observed from a first direction in which the first plane is facing when the flexible display panel is not bent, is larger than an area ratio of the second non-display region to the display region as observed from the first direction when the flexible display panel is bent.

5. The flexible display panel of claim 1 ,

wherein the border region has a curved surface having a curvature radius.

6. The flexible display panel of claim 5 , wherein the curvature radius is constant.

7. The flexible display panel of claim 6 , wherein the curvature radius is between 0.01 mm and 10 mm.

8. The flexible display panel of claim 5 , wherein the curved surface has an arc shape.

9. The flexible display panel of claim 5 , wherein the display region extension extends to the second non-display region on the second plane.

10. The flexible display panel of claim 5 , wherein the second non-display region extends into the border region.

11. The flexible display panel of claim 1 , wherein the second non-display region on the second plane extends onto a third plane that is bent with respect to the second plane and substantially parallel to the first plane.

12. The flexible display panel of claim 11 , wherein the second non-display region on the third plane includes a pad unit.

13. The flexible display panel of claim 1 , wherein the encapsulated panel further comprises a barrier layer between the flexible substrate and the layer.

14. The flexible display panel of claim 1 , wherein the first protective film and the second protective film are symmetrical with each other.

15. The flexible display panel of claim 1 , wherein the first protective film or the second protective film comprises a polarization film.

16. The flexible display panel of claim 1 , wherein the first protective film covers the flexible substrate and the second protective film covers the flexible encapsulation member.

17. The flexible display panel of claim 1 , wherein the flexible encapsulation member comprises an insulating layer comprising an inorganic layer or an organic layer.

18. The flexible display panel of claim 1 , further comprising a touch panel on the encapsulated panel and configured to display an image on the display region and the display region extension.

19. The flexible display panel of claim 18 , wherein the touch panel comprises a flexible film that is bent to correspond to a shape of the flexible display panel.

20. The flexible display panel of claim 19 , wherein the touch panel comprises:

a touch region on the flexible film and corresponding to the display region and the display region extension; and

a wiring region outside the touch region.

21. The flexible display panel of claim 1 , wherein the second protective film covers the display region and leaves the second non-display region uncovered.

22. The flexible display panel of claim 1 , wherein the second protective film covers the display region and the display region extension, and leaves the first non-display region and the second non-display region uncovered.

23. A display apparatus having a display region and a first non-display region on a first plane, a second non-display region on a second plane that is bent with respect to the first plane, and an extension of the display region into a border region between the display region on the first plane and the second non-display region on the second plane, the display apparatus comprising:

a first protective film;

a flexible encapsulated panel on the first protective film and comprising:

a flexible substrate;

a layer on the flexible substrate and in each of the display region, the display region extension, the first non-display region, and the second non-display region; and

a flexible encapsulation member on the flexible substrate to encapsulate the layer therebetween;

a second protective film on the flexible encapsulated panel; and

a support unit for maintaining a shape of the flexible encapsulated panel.

24. The display apparatus of claim 23 , wherein the support unit comprises a transparent protection window.
