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 (37)

1. A display apparatus comprising:

a first protective film;

a substrate on the first protective film;

a display region and a first non-display region disposed on a first plane of the substrate;

a second non-display region on a second plane of the substrate, wherein the second plane is bent with respect to the first plane;

a border region between the display region and the second non-display region, the border region extending from the display region and displaying an image; and

an encapsulation member on the display region,

wherein at least one selected from a scan circuit unit, a data circuit unit and a driving power wiring unit is located in the second non-display region.

2. The display apparatus of claim 1 , wherein the border region has a curved surface having a curvature radius.

3. The display apparatus of claim 2 , wherein the curvature radius is constant.

4. The display apparatus of claim 2 , wherein the curvature radius is between 0.01 mm and 10 mm.

5. The display apparatus of claim 2 , wherein the curved surface has an arc shape.

6. The display apparatus of claim 1 , wherein border regions are located on both sides of the display region.

7. The display apparatus of claim 6 , wherein the border regions face each other.

8. The display apparatus of claim 1 , wherein the substrate is a flexible substrate comprising a plastic material.

9. The display apparatus of claim 1 , wherein the first non-display region is bent with respect to the display region.

10. The display apparatus of claim 9 , wherein a portion of the first non-display region is bent to face the display region.

11. The display apparatus of claim 10 , wherein the portion of the first non-display region includes a pad unit.

12. The display apparatus of claim 9 , wherein the first non-display region is adjacent to the second non-display region, and

wherein corners of the first and the second non-display regions are cut off.

13. The display apparatus of claim 1 , wherein the scan circuit unit is configured to transmit a driving signal to the display region, the data circuit unit is configured to transmit a data signal to the display region, and the driving power wiring unit is configured to supply a driving power to the display region.

14. The display apparatus of claim 1 , wherein the scan circuit unit is located in the second non-display region and the data circuit unit or the driving power wiring unit is located in the first non-display region.

15. The display apparatus of claim 1 , wherein the display apparatus further comprises a second protective film on the encapsulation member.

16. The display apparatus of claim 15 , wherein the first protective film and the second protective film are substantially symmetrical with each other.

17. The display apparatus of claim 15 , wherein the first protective film or the second protective film comprises a polarization film.

18. The display apparatus of claim 15 , wherein the encapsulation member comprises a first inorganic insulating layer, an organic insulating layer, and a second inorganic insulating layer, which are sequentially stacked, and

wherein the second protective film covers an end of the encapsulation member.

19. The display apparatus of claim 1 , wherein the display apparatus further comprises a barrier layer between the substrate and the display region, the first non-display region, the second non-display region, and the border region.

20. The display apparatus of claim 1 , further comprising an electrode power supply line located in the first non-display region and the second non-display region.

21. The display apparatus of claim 1 , further comprising a transparent protection window on the encapsulation member.

22. The display apparatus of claim 21 , wherein the transparent protection window is disposed on the encapsulation member to correspond to shapes of the display region, the border region, and the second non-display region.

23. The display apparatus of claim 21 , wherein the transparent protection window functions as a support unit for maintaining shapes of the display region, border region, and the second non-display region.

24. The display apparatus of claim 1 , wherein the encapsulation member is further disposed on the border region and the second non- display region.

25. The display apparatus of claim 24 , wherein a touch region is disposed on the display region and the border region, and wherein touch wirings are disposed on the second non-display region.

26. The display apparatus of claim 24 , further comprising a touch region and touch wirings in wiring regions outside the touch region being disposed on the encapsulation member.

27. The display apparatus of claim 25 , wherein the encapsulation member comprises inorganic insulating layers and an organic insulating layer.

28. The display apparatus of claim 25 , wherein the touch region and the touch wirings are bent to correspond to shapes of the display region and the first and second non-display regions.
