Abstract

A display device includes: a first touch electrode; a first touch pad electrically connected to the first touch electrode by a touch wire; and a first dummy pad not connected to the touch wire, and disposed adjacent to the first touch pad, wherein a width of the first touch pad is greater than a width of the first dummy pad.

Claims (48)

1. A display device comprising:

a first touch electrode;

a touch pad portion electrically connected to the first touch electrode by a touch signal line; and

a plurality of first dummy pads not connected to the touch signal line;

wherein the touch pad portion comprises a plurality of first touch pads disposed in a first region and a plurality of second touch pads disposed in a second region,

wherein the plurality of first touch pads and the plurality of second touch pads are arranged along a first direction,

wherein the plurality of first dummy pads are disposed between the plurality of first touch pads and arranged along the first direction,

wherein a width of one of the plurality of first touch pads is larger than a width of one of the plurality of first dummy pads, and

wherein the first region and the second region are adjacent according to a second direction crossing the first direction.

2. The display device of claim 1 , further comprising:

a plurality of second dummy pads not connected to the touch signal line,

wherein the plurality of second dummy pads are disposed between the plurality of second touch pads and arranged along the first direction.

3. The display device of claim 2 , wherein

the plurality of first dummy pads are disposed in the first region,

the plurality of second dummy pads are disposed in the second region, and

the first region and the second region are separated from each other.

4. The display device of claim 3 , wherein

the plurality of first touch pads and the plurality of first dummy pads are alternately disposed along the first direction, and

the plurality of second touch pads and the plurality of second dummy pads are alternately disposed along the first direction.

5. The display device of claim 3 , wherein

the plurality of first dummy pads and the plurality of second dummy pads are in floating.

6. The display device of claim 3 , wherein

the plurality of first dummy pads and the plurality of second dummy pads are not receive any voltages.

7. The display device of claim 3 , further comprising a second touch electrode,

wherein the first touch electrode includes first touch cells arranged in the first direction and first connectors connecting the first touch cells to each other, and

wherein the second touch electrode includes second touch cells arranged in the second direction and second connectors connecting the second touch cells to each other.

8. The display device of claim 7 , wherein

the first touch electrode includes fine electrode lines traversing each other and an opening between the fine electrode lines.

9. The display device of claim 8 , further comprising

a flexible printed circuit substrate electrically connected to the touch pad portion.

10. A display device comprising:

a first touch electrode;

a touch pad portion electrically connected to the first touch electrode by a touch signal line; and

a plurality of dummy pads in floating,

wherein the touch pad portion comprises a plurality of first touch pads and a plurality of second touch pads,

wherein the plurality of first touch pads and the plurality of dummy pads are arranged along a first direction in a first region,

wherein the plurality of second touch pads and the plurality of dummy pads are arranged along a first direction in a second region, and

wherein a width of one of the plurality of first touch pads is larger than a width of one of the plurality of first dummy pads, and

wherein the first region and the second region are adjacent according to a second direction crossing the first direction.

11. The display device of claim 10 , wherein

the plurality of first touch pads and the plurality of dummy pads are alternately disposed along the first direction in the first region, and

the plurality of second touch pads and the plurality of dummy pads are alternately disposed along the first direction in the second region.

12. The display device of claim 11 , wherein

the first region and the second region are separated from each other.

13. The display device of claim 10 , wherein

the plurality of first dummy pads and the plurality of second dummy pads are not receive any voltages.

14. The display device of claim 10 , further comprising

a flexible printed circuit substrate electrically connected to the touch pad portion.
