Abstract

An electronic device including: a display panel having an active area in which a plurality of pixels are disposed and a peripheral area disposed around the active area; a plurality of sensing electrodes disposed in the active area; and a first sensing line connected to one of the plurality of sensing electrodes and including a first portion disposed in the peripheral area, a second portion extending from the first portion and disposed in the active area, and a third portion extending from the second portion and disposed in the peripheral area.

Claims (43)

1. An electronic device in which an active area and a peripheral area around the active area are defined comprising:

electrodes disposed in the active area and comprising first electrodes and second electrodes crossing the first electrodes; and

trace lines electrically connected to the electrodes, respectively,

wherein:

the trace lines include a first trace line including a first portion overlapping the active area and a second trace line including a second portion overlapping the active area, each of the first and second portions extending from one side of the active area to another side of the active area adjacent to the one side;

a length of the first portion is different from a length of the second portion;

the first trace line is electrically connected to one of the first electrodes; and

the second trace line is electrically connected to another one of the first electrodes.

2. The electronic device of claim 1 , wherein each of the first portion and the second portion has a mesh structure.

3. The electronic device of claim 1 , wherein a length of the second trace line is longer than a length of the first trace line, and the length of the second portion is shorter than the length of the first portion.

4. The electronic device of claim 1 , wherein the second portion is closer to the peripheral area than the first portion.

5. The electronic device of claim 1 , wherein a width of the first portion and a width of the second portion are the same.

6. The electronic device of claim 1 , wherein a width of the second portion is greater than a width of the first portion.

7. The electronic device of claim 1 , wherein a width of a mesh line included in the second portion is greater than a width of a mesh line included in the first portion.

8. The electronic device of claim 1 , wherein a resistance of the second portion is smaller than a resistance of the first portion.

9. The electronic device of claim 1 , wherein:

each of the first electrodes includes sensing patterns and connection patterns; and

the sensing patterns and the connection patterns are disposed on different layers.

10. The electronic device of claim 9 , wherein the first portion and the second portion are disposed on a same layer as the sensing patterns.

11. The electronic device of claim 9 , wherein the first portion and the second portion are disposed on a same layer as the connection patterns.

12. The electronic device of claim 1 , wherein a boundary is disposed between the active area and the peripheral area, and the boundary comprises a partially curved boundary.

13. The electronic device of claim 1 , wherein:

the first trace line further includes first connection portions electrically connected to the first portion and disposed in the peripheral area;

the second trace line further includes second connection portions electrically connected to the second portion and disposed in the peripheral area; and

the first connection portions are connected to one end and the other end of the first portion, respectively, and the second connection portions are respectively connected to one end and the other end of the second portion.

14. An electronic device comprising:

a display panel in which an active area displaying an image and a peripheral area around the active area are defined; and

a sensor disposed on the display panel and including electrodes disposed in the active area and trace lines electrically connected to the electrodes, respectively,

wherein:

the trace lines include a first trace line including a first portion overlapping the active area and a first connection portion overlapping the peripheral area, and a second trace line including a second portion overlapping the active area and a second connection portion overlapping the peripheral area;

a length of the first trace line is less than a length of the second trace line, and a resistance of the first portion is greater than a resistance of the second portion; and

each of the first and second portions extends from one side of the active area to another side of the active area adjacent to the one side, and includes parts extending in a plurality of different directions.

15. The electronic device of claim 14 , wherein a length of the second portion is less than a length of the first portion.

16. The electronic device of claim 14 , wherein a width of the second portion is greater than or equal to a width of the first portion.

17. The electronic device of claim 14 , wherein:

each of the first portion and the second portion has a mesh structure; and

a width of a mesh line included in the second portion is greater than a width of a mesh line included in the first portion.

18. The electronic device of claim 14 , wherein:

the electrodes comprise first electrodes and second electrodes crossing the first electrodes;

each of the first electrodes includes sensing patterns and connection patterns; and

the sensing patterns and the connection patterns are disposed on different layers.

19. The electronic device of claim 18 , wherein the first portion and the second portion are disposed on a same layer as the sensing patterns.

20. The electronic device of claim 18 , wherein the first portion and the second portion are disposed on a same layer as the connection patterns.
