Abstract

Disclosed is a touch window including a sensing electrode to sense a position, and a wire to electrically connect the sensing electrode. A width of the sensing electrode is variable in the sensing electrode.

First claim

1 . A touch window comprising:
a sensing electrode having a mesh shape that includes:
a plurality of first conductive lines in a first direction,
a plurality of second conductive lines in a second direction; and
a wire including a wire pad, wherein the wire pad includes a side being in contact with the sensing electrode, wherein the first conductive lines and the second conductive lines cross each other to form a plurality of connecting portions, the plurality of connecting portions including, at least one first connecting portion being closest to the wire pad, and the at least one first connecting portion having an outer line portion extending toward the wire pad and an inner line portion extending toward an adjacent connecting portion, wherein the outer line portion of the first conductive line includes:
a first part having a uniform width in a first direction, and
a second part disposed between the wire pad and the first part,
wherein a width of the second part varies, in a direction parallel to the side of the wire pad, as the second part extends from the first part to the wire pad.

2 . The touch window of claim 1 , wherein the width of the second part increases, in the direction parallel to the side of the wire pad, as the second part extends from the first part to the wire pad.

3 . The touch window of claim 2 , wherein a maximum width of the second part is larger than the width of the first part.

4 . The touch window of claim 3 , wherein the maximum width of the second part is longer than a cross width of the connecting portions.

5 . The touch window of claim 2 , wherein a minimum width of the second part is same as the width of the first part.

6 . The touch window of claim 1 , wherein distances between two adjacent second parts, in the direction parallel to the side of the wire pad, are decreased as the second part extends from the first part to the wire pad.

7 . The touch window of claim 6 , wherein the distances between the two adjacent second parts is different from a distance between two adjacent first parts.

8 . The touch window of claim 6 , wherein a distance between two adjacent first parts, in the direction parallel to the side of the wire pad, is continually the same.

9 . The touch window of claim 1 , wherein the width of the second part is different than the width of the first part.

10 . The touch window of claim 1 , further comprising a substrate, wherein the touch window has a plurality of sensing electrodes and a plurality of wires are in contact with the plurality of sensing electrodes.

11 . The touch window of claim 1 , wherein at least two outer line portions directly contact the wire pad.

12 . A touch window comprising:
a sensing electrode having a mesh shape that includes:
a plurality of first conductive lines in a first direction;
a plurality of second conductive lines in a second direction; and
a wire including a wire pad, wherein the wire pad includes a side being in contact with the sensing electrode, wherein, the first conductive lines and the second conductive lines cross each other to form a plurality of connecting portions, the plurality of connecting portions including at least one first connecting portion being immediately adjacent to the wire pad, and the at least one first connecting portion having an outer line portion extending toward the wire pad and an inner line portion extending toward an adjacent connecting portion, wherein the outer line portion of the first conductive line includes:
a first part having a uniform width in a first direction, and
a second part disposed between the wire pad and the first part,
wherein a width of the second part varies, in a direction parallel to the side of the wire pad, as the second part extends from the first part to the wire pad.

13 . The touch window of claim 12 , wherein the width of the second part increases, in the direction parallel to the side of the wire part, as the second part extends from the first part to the wire pad.

14 . The touch window of claim 13 , wherein the width of the second part is different than the width of the first part.

15 . (canceled)

16 . The touch window of claim 13 , wherein a maximum width of the second part is larger than the width of the first part.

17 . The touch window of claim 16 , wherein the maximum width of the second part is longer than a cross width of the connecting portions.

18 . The touch window of claim 13 , wherein a minimum width of the second part is same as the width of the first part.

19 . The touch window of claim 22 , wherein the distances between the two adjacent second parts is different from a distance between two adjacent first parts.

20 . The touch window of claim 12 , wherein a distance between two adjacent first parts, in the direction parallel to the side of the wire pad, is continually the same.

21 . The touch window of claim 12 , wherein at least two outer line portions directly contact the wire pad.

22 . The touch window of claim 12 , wherein distances between two adjacent second parts, in the direction parallel to the side of the wire pad, are decreased as the second part extends from the first part to the wire pad.

23 . A touch window comprising:
a sensing electrode having a mesh shape that includes:
a plurality of first conductive lines in a first direction,
a plurality of second conductive lines in a second direction different from the first direction to form a plurality of intersections between the first and second conductive lines; and
a wire including a wire pad, wherein the wire pad includes a side being in contact with a plurality of contact portions of the sensing electrode, each contact portion only comprising:
a single first part having a uniform width, and
a single second part connected to the single first part and the side of the wire pad,
wherein a width of the single second part varies, in a direction parallel to the side of the wire pad, as the single second part extends from the single first part to the side of wire pad, wherein the single first part being connected to a single corresponding intersection of first and second conductive lines.

24 . The touch window of claim 23 , wherein the width of the single second part increases, in the direction parallel to the side of the wire pad, as the single second part extends from the single first part to the wire pad.

25 . The touch window of claim 23 , wherein a maximum width of the single second part is larger than the width of the single first part.

26 . The touch window of claim 23 , wherein a minimum width of the single second part is same as the width of the single first part.
