Abstract

A touch sensing unit includes a first electrode including a plurality of first main patterns arranged in a first direction and a first outer pattern arranged on one sides of the plurality of first main patterns, a second electrode including a plurality of second main patterns arranged in a second direction intersecting the first direction and a second outer pattern arranged on one sides of the plurality of second main patterns, a first compensation pattern extending along an edge of the first outer pattern, and a first signal wire connected to at least one of the first outer pattern and the first compensation pattern. The first compensation pattern includes a first compensation connection part protruding toward the first outer pattern and connected to the first outer pattern.

Claims (50)

1. A touch sensing unit, comprising:

a first electrode including a plurality of first main patterns arranged in a first direction and a first outer pattern arranged on a side of the plurality of first main patterns;

a second electrode including a plurality of second main patterns arranged in a second direction intersecting the first direction and a second outer pattern arranged on a side of the plurality of second main patterns;

a first compensation pattern disposed within a touch peripheral area of the touch sensing unit that circumscribes the first and second electrodes, the first compensation pattern extending along an outer edge of the first outer pattern; and

a first signal wire connected to the first outer pattern and/or the first compensation pattern,

wherein the first compensation pattern includes a first compensation connection part protruding toward the first outer pattern and the first compensation connection part is connected to the first outer pattern.

2. The touch sensing unit of claim 1 , wherein the first compensation connection part at least partially overlaps the first outer pattern.

3. The touch sensing unit of claim 1 , further comprising:

a touch sensing area that senses a touch; and

the touch peripheral area at least partially surrounds the touch sensing area,

wherein the first electrode and the second electrode are arranged in the touch sensing area, and the first signal wire is disposed in the touch peripheral area.

4. The touch sensing unit of claim 3 , wherein the first compensation pattern includes a first compensation peripheral part disposed between the first outer pattern and the first signal wire.

5. The touch sensing unit of claim 4 , wherein the first compensation periphery part is disposed within the touch peripheral area.

6. The touch sensing unit of claim 4 , further comprising:

a second compensation pattern extending along an edge of the second outer pattern; and

a second signal wire connected to the second outer pattern and/or the second compensation pattern,

wherein the first compensation peripheral part is disposed between the first signal wire and the second signal wire.

7. The touch sensing unit of claim 6 , further comprising a guard wire disposed between the first signal wire and the second signal wire.

8. The touch sensing unit of claim 1 , wherein an area of the first compensation pattern s greater than an area of the first outer pattern.

9. The touch sensing unit of claim 1 , wherein an area of the first outer pattern is smaller than an area of the first main pattern.

10. The touch sensing unit of claim 1 , further comprising:

a substrate;

a first touch conductive layer disposed on the substrate;

a first touch insulating layer disposed on the first touch conductive layer; and

a second touch conductive layer disposed on the first touch insulating layer,

wherein the first touch conductive layer includes the first signal wire and the first compensation pattern, and

wherein the second touch conductive layer includes the first main pattern, the second main pattern, the first outer pattern, and the second outer pattern.

11. The touch sensing unit of claim 1 , wherein the second outer pattern includes a protrusion part protruding toward the first outer pattern.

12. The touch sensing unit of claim 11 , wherein the second outer pattern is disposed between the first compensation pattern and the first main pattern in the second direction.

13. A touch sensing unit, comprising:

a first electrode including a plurality of first main patterns arranged in a first direction and a first outer pattern arranged on a side of the plurality of first main patterns;

a second electrode including a plurality of second main patterns arranged in a second direction intersecting the first direction and a second outer pattern arranged on a side of the plurality of second main patterns;

a third electrode including a plurality of third main patterns arranged in the first direction and a third outer pattern arranged on a side of the plurality of third main patterns; and

a first compensation pattern disposed within a touch peripheral area of the touch sensing unit that circumscribes the first, second and third electrodes, the first compensation pattern extending along outer edges of the first outer pattern and the third outer pattern,

wherein the first compensation pattern is electrically connected to the first outer pattern.

14. The touch sensing unit of claim 13 , wherein the first electrode and the third electrode are adjacent to each other in the second direction.

15. The touch sensing unit of claim 14 , further comprising a second compensation pattern connected to the second outer pattern,

wherein the second compensation pattern is arranged along edges of the first outer pattern, the second outer pattern, and the third outer pattern.

16. A display device, comprising:

a display panel including a light emitting element layer including light emitting elements that emit light and a touch sensing layer disposed on the light emitting element layer; and

a window disposed on the display panel and including a light blocker,

wherein the touch sensing layer includes:

a first electrode including a plurality of first main patterns arranged in a first direction and a first outer pattern arranged on a side of the plurality of first main patterns;

a second electrode including a plurality of second main patterns arranged in a second direction intersecting the first direction and a second outer pattern arranged on a side of the plurality of second main patterns; and

a first compensation pattern disposed within a touch peripheral area of the touch sensing layer that circumscribes the first and second electrodes, the first compensation pattern connected to the first outer pattern,

wherein the first compensation pattern at least partially overlaps the light blocker.

17. The display device of claim 16 , wherein the first compensation pattern includes a first compensation peripheral part extending along an outer edge of the first outer pattern and a first compensation connection pan protruding from the first compensation peripheral part to the first outer pattern and connected to the first outer pattern.

18. The display device of claim 17 , wherein the first compensation peripheral part at least partially overlaps the light blocker.

19. The display device of claim 18 , wherein at least a first portion of the first compensation connection part overlaps the light blocker.

20. The display device of claim 19 , wherein at least a second portion of the first compensation connection part overlaps the first outer pattern.
