Abstract

An electronic device includes a first electrode, a second electrode, and a third electrode. The first electrode includes a first boundary side extending in a direction. The second electrode includes a second boundary side extending in the direction. The third electrode is disposed between and spaced apart from the first electrode and the second electrode. The third electrode includes a first side facing the first boundary side and a second side facing the second boundary. The first side and the second side have shapes that are asymmetric to each other with respect to a center axis extending in the direction.

Claims (62)

1. An electronic device, comprising:

a display member comprising:

a display device layer configured to display an image; and

an encapsulation layer covering the display device layer;

an insulating layer disposed directly on the encapsulation layer;

a first electrode and a second electrode disposed on the insulating layer and spaced apart from each other; and

a third electrode disposed on the insulating layer and disposed between the first electrode and the second electrode,

wherein:

the third electrode is extended in a direction and comprises a first side and a second side opposing the first side;

the first electrode comprises a first boundary side facing the first side of the third electrode; and

the second electrode comprises a second boundary side facing the second side of the third electrode;

the first boundary side and the second boundary side have shapes that are asymmetric to each other with respect to a center axis overlapping the third electrode.

2. The electronic device of claim 1 , wherein:

the first side has a shape corresponding to the first boundary side; and

the second side has a shape corresponding to the second boundary side.

3. The electronic device of claim 2 , wherein:

a width of the third electrode in an intersecting direction crossing the direction varies along the direction, and

the center axis passes through centers of potions of the third electrode having minimum width in the intersecting direction.

4. The electronic device of claim 2 , wherein

the third electrode comprises:

a first portion comprising the first side; and

a second portion comprising the second side, the first portion and the second portion being divided by the center axis; and

the first portion has an area that is different from an area of the second portion.

5. The electronic device of claim 4 , wherein:

the first electrode has an area larger than an area of the second electrode; and

the area of the first portion is smaller than the area of the second portion.

6. The electronic device of claim 1 , wherein at least one of the first electrode and the second electrode comprises:

a sensor part adjacent to the third electrode; and

a floating pattern spaced apart from the third electrode with the sensor part disposed therebetween, the floating pattern being electrically disconnected from the sensor part.

7. The electronic device of claim 6 , wherein:

the floating pattern comprises:

a first floating side extending in the direction; and

a second floating side extending in an intersecting direction, the first floating side being connected to the second floating side; and

at least one of the first side and the second side has a same shape as a shape of the first floating side.

8. The electronic device of claim 7 , wherein the first floating side has a straight line shape extending in the direction.

9. The electronic device of claim 7 , wherein the first floating side comprises a plurality of protruding patterns extending in the direction and protruding toward the sensor part.

10. The electronic device of claim 1 , wherein:

the first side comprises a plurality of first protruding patterns protruding toward the first electrode, the plurality of first protruding patterns being spaced apart from one another according to a first pitch; and

the second side comprises a plurality of second protruding patterns protruding toward the second electrode, the plurality of second protruding patterns being spaced apart from one another according to a second pitch.

11. The electronic device of claim 10 , wherein the first pitch is substantially the same as the second pitch.

12. The electronic device of claim 11 , wherein:

the plurality of first protruding patterns and the plurality of second protruding patterns have the same shape; and

the plurality of first protruding patterns and the plurality of second protruding patterns comprise at least portions that do not overlap each other in an intersecting direction.

13. The electronic device of claim 10 , wherein the plurality of first protruding patterns and the plurality of second protruding patterns have shapes different from each other.

14. The electronic device of claim 10 , wherein the first pitch is smaller than the second pitch.

15. The electronic device of claim 14 , wherein an area of each of the plurality of first protruding patterns is smaller than that an area of each of the plurality of second protruding patterns.

16. The electronic device of claim 1 , wherein:

each of the first electrode, the second electrode, and the third electrode comprises:

a plurality of first mesh lines spaced apart from each other in an intersecting direction, each of the plurality of first mesh lines extending in the direction; and

a plurality of second mesh lines spaced apart from each other in the direction and connected to the plurality of first mesh lines, each of the plurality of second mesh lines extending in the intersecting direction and crossing the plurality of first mesh lines; and

each of the first boundary side, the second boundary side, the first side, and the second side is defined by an imaginary cutting line connecting cut portions of the plurality of first mesh lines and the plurality of second mesh lines.

17. The electronic device of claim 1 , wherein the first electrode, the second electrode, and the third electrode are disposed in the same layer.

18. An electronic device, comprising:

a display member configured to display an image;

an insulating layer disposed on the display member; and

a mesh structure having a plurality of mesh lines,

wherein:

a first cutting line and a second cutting line are defined in the mesh structure to form a first electrode, a second electrode, and a third electrode by cutting corresponding mesh lines of the plurality of the mesh lines;

the third electrode is disposed between the first electrode and the second electrode; and

the first cutting line and the second cutting line have shapes that are asymmetric to each other with respect to a center axis overlapping the third electrode.

19. The electronic device of claim 18 , wherein the first electrode, the second electrode, and the third electrode are configured to receive different signals.

20. The electronic device of claim 18 , wherein a length of the first cutting line differs from a length of the second cutting line.
