Abstract

A flexible display panel including: a flexible panel including a first region including a display region and oriented on a first plane and a second region including a non-display region and oriented on a second plane different from the first plane; and a flexible encapsulation member disposed on the flexible panel so as to encapsulate at least the display region.

Claims (71)

1. A display apparatus comprising:

a first protective film;

a flexible substrate on the first protective film;

a display region on the flexible substrate;

a first non-display region bent with respect to the display region;

a second non-display region bent with respect to the first non-display region, the second non-display region facing the display region;

a flexible encapsulation member disposed on the display region and the first non-display region;

a touch region and touch wirings outside the touch region, the touch region and touch wirings being disposed on the flexible encapsulation member, the touch region being disposed at a position corresponding to the display region, and the touch wirings being disposed at a position corresponding to the first non-display region; and

a pad unit on the second non-display region.

2. The display apparatus of claim 1 , wherein the touch region and the touch wirings are bent to correspond to shapes of the display region and the first non-display region.

3. The display apparatus of claim 1 , further comprising:

a transparent protective window disposed on the touch region and touch wirings,

wherein the transparent protective window functions as a support unit for maintaining shapes of the display region and the first non-display region.

4. The display apparatus of claim 3 , further comprising:

a second protective film between the flexible encapsulation member and the transparent protective window.

5. The display apparatus of claim 4 , further comprising:

an adhesive between the second protective film and the transparent protective window.

6. The display apparatus of claim 4 , wherein the first protective film and the second protective film are arranged to be symmetrical with each other.

7. The display apparatus of claim 4 , wherein the second protective film comprises a polarization film.

8. The display apparatus of claim 1 , further comprising:

wiring lines outside the display region, the wiring lines being connected to the display region,

wherein the pad unit is connected to the wiring lines.

9. The display apparatus of claim 8 , wherein the wiring lines comprise a first wiring line and a second wiring line facing the first wiring line,

a distance between the first wiring line and the second wiring line on a first axis is greater than a distance between the first wiring line and the second wiring line on a second axis,

the first axis is a bending axis between the display region and the first non-display region, and

the second axis is a bending axis between the first non-display region and the second non-display region.

10. The display apparatus of claim 9 , wherein the touch wirings comprise a third touch wiring and a fourth touch wiring facing the third touch wiring,

a distance between the third touch wiring and the fourth touch wiring on a first axis is greater than a distance between the first wiring line and the second wiring line on a second axis.

11. The display apparatus of claim 1 , wherein the flexible encapsulation member comprises layers stacked in an order of a first inorganic layer, an organic layer and a second inorganic layer.

12. A display apparatus comprising:

a first protective film;

a flexible substrate on the first protective film;

a display region on the flexible substrate;

a first non-display region bent with respect to the display region;

a second non-display region bent with respect to the display region, the second non-display region facing the first non-display region;

a third non-display region bent with respect to the display region, the third non-display region being disposed between the first non-display region and the second non-display region;

a fourth non-display region bent with respect to the display region, the fourth non-display region facing the second non-display region;

a flexible encapsulation member disposed on the display region and the first to fourth non-display regions;

a touch region and touch wirings outside the touch region, the touch region and touch wirings being disposed on the flexible encapsulation member, the touch region being disposed at a position corresponding to the display region, and the touch wirings being disposed at a position corresponding to the first to fourth non-display regions; and

a pad unit on at least one of the first to fourth non-display regions,

wherein a corner between the first non-display region and the third non-display region and a corner between the first non-display region and the fourth non-display region are cut off; and

wherein a corner between the second non-display region and the third non-display region and a corner between the second non-display region and the fourth non-display region are cut off.

13. The display apparatus of claim 12 , wherein the touch region and the touch wirings are bent to respectively correspond to shapes of the display region and the first to fourth non-display regions.

14. The display apparatus of claim 12 , further comprising:

a transparent protective window disposed on the touch region and touch wirings,

wherein the transparent protective window functions as a support unit for maintaining shapes of the display region and the first to fourth non-display regions.

15. The display apparatus of claim 12 , further comprising:

wiring lines outside the display region, the wiring lines being connected to the display region,

wherein the pad unit is connected to the wiring lines.

16. The display apparatus of claim 12 , wherein the flexible encapsulation member comprises layers stacked in an order of a first inorganic layer, an organic layer and a second inorganic layer.

17. A display apparatus comprising:

a first protective film;

a flexible substrate on the first protective film;

a display region on the flexible substrate;

a first non-display region bent with respect to the display region;

a second non-display region bent with respect to the display region, the second non-display region facing the first non-display region;

a third non-display region bent with respect to the display region, the third non-display region being disposed between the first non-display region and the second non-display region;

a fourth non-display region bent with respect to the display region, the fourth non-display region facing the second non-display region;

a flexible encapsulation member disposed on the display region and the first to fourth non-display regions;

a touch region and touch wirings outside the touch region, the touch region and touch wirings being disposed on the flexible encapsulation member, the touch region being disposed at a position corresponding to the display region, and the touch wirings being disposed at a position corresponding to the first to fourth non-display regions;

a pad unit on at least one of the first to fourth non-display regions, and

a transparent protective window disposed on the touch region and touch wirings,

wherein the transparent protective window functions as a support unit for maintaining shapes of the display region and the first to fourth non-display regions,

wherein a corner between the first non-display region and the third non-display region and a corner between the first non-display region and the fourth non-display region are cut off; and
