Abstract

A display device including a display panel having a first area, a second area spaced from the first area, and a bending area disposed between the first and second areas, a first sensing pattern overlapped with the first area, a second sensing pattern spaced apart from the first sensing pattern and overlapped with the second area, and a first non-functional pattern overlapped with the bending area and spaced apart from each of the first and second sensing patterns.

First claim

What is claimed is:

1. A display device, comprising:
a display panel including a first area, a second area spaced from the first area, and a bending area disposed between the first and second areas;
a first sensing pattern corresponding to the first area;
a second sensing pattern spaced apart from the first sensing pattern and corresponding to the second area; and
a first non-functional pattern overlapped with the bending area and spaced apart from each of the first and second sensing patterns,
wherein:
the first non-functional pattern comprises a plurality of first dummy patterns arranged in an irregular manner; and
the first sensing pattern, the second sensing pattern, and the first non-functional pattern are disposed in the same layer.

2. The display device of claim 1 , wherein the bending area is configured to be bendable about at least one bending axis,
the first and second areas are substantially inflexible, and
the first non-functional pattern is electrically disconnected from each of the first and second sensing patterns.

3. The display device of claim 1 , further comprising:
a third sensing pattern overlapped with the first area; and
a fourth sensing pattern spaced apart from the third sensing pattern and overlapped with the second area,
wherein the third and fourth sensing patterns are disposed in the same layer.

4. The display device of claim 3 , further comprising a second non-functional pattern overlapped with the bending area and spaced apart from each of the third and fourth sensing patterns
wherein the second non-functional pattern, the third sensing pattern, and the fourth sensing pattern are disposed in the same layer.

5. The display device of claim 4 , wherein the second non-functional pattern is disposed over the first non-functional pattern.

6. The display device of claim 3 , wherein the first and second sensing patterns are configured to sense a position of an external touch, and
the third and fourth sensing patterns are configured to sense pressure of the external touch.

7. The display device of claim 1 , wherein the first non-functional pattern comprises substantially the same material as the first and second sensing patterns.

8. The display device of claim 1 , wherein the first sensing pattern, the second sensing pattern, and the first dummy pattern are disposed in the same layer.

9. The display device of claim 1 , wherein the first sensing pattern and the second sensing pattern do not overlap with the bending area.

10. A display device, comprising:
a display panel including a first area, a second area spaced from the first area, and a bending area disposed between the first and second areas;
a first sensing pattern corresponding to the first area;
a second sensing pattern spaced apart from the first sensing pattern and corresponding to the second area;
a first non-functional pattern overlapped with the bending area and spaced apart from each of the first and second sensing patterns; and
a pressure sensing pattern overlapped with the display panel,
wherein the first sensing pattern, the second sensing pattern, and the first non-functional pattern are disposed in the same layer.

11. The display device of claim 10 , wherein the first and second sensing patterns are configured to sense a position of an external touch, and
the pressure sensing pattern is configured to sense pressure of the external touch.

12. The display device of claim 10 , wherein the bending area is configured to be bendable about at least one bending axis, and
the first and second areas are configured to be substantially inflexible.

13. The display device of claim 10 , wherein the first non-functional pattern comprises a plurality of first dummy patterns arranged in an irregular manner.

14. The display device of claim 10 , wherein the pressure sensing pattern comprises:
a third sensing pattern overlapped with the first area;
a fourth sensing pattern spaced apart from the third sensing pattern and overlapped with the second area; and
a second non-functional pattern overlapped with the bending area and spaced apart from each of the third and fourth sensing patterns.

15. The display device of claim 14 , wherein the third and fourth sensing patterns are configured to sense pressure of an external touch.

16. The display device of claim 14 , wherein the second non-functional pattern comprises a plurality of second dummy patterns.

17. The display device of claim 16 , wherein the second dummy patterns are arranged in an irregular manner.

18. The display device of claim 14 , wherein the second non-functional dummy pattern, the third sensing pattern, and the fourth sensing pattern are disposed in the same layer.
