Abstract

According to various embodiments of the present invention, an electronic device may comprise a touch layer in which a sensor may be disposed below a designated area, wherein the touch layer comprises: a first touch line including a first touch electrode and a second touch electrode arranged in a first direction in the designated area; a second touch line including a third touch electrode and a fourth touch electrode arranged in a second direction while crossing the first touch line in the designated area; a first opening formed in the area where the first touch line and the second touch line cross each other; and a first connection wiring disposed in the peripheral portion of the first opening and connecting the first touch electrode and the second touch electrode to each other. Various other embodiments are also possible.

First claim

What is claimed is:

1. A portable communication device comprising:
a touchscreen display including a touch sensing layer having an opening formed therein; and
a sensor disposed as at least partially overlapped with the opening when viewed in a direction substantially perpendicular to the touchscreen display,
wherein the touch sensing layer includes:
a first touch electrode disposed at a first side with respect to the opening;
a second touch electrode disposed at a second side different from the first side with respect to the opening; and
a connection line connecting the first touch electrode and the second touch electrode along at least a part of a boundary of the opening,

wherein the connecting line comprises:
a first part having a first length and a first width, the first part located closer to the first touch electrode than to the second touch electrode; and
a second part having a second length and a second width wider than the first width, the second part located closer to the second touch electrode than to the first touch electrode, and

wherein the first part and the second part together connect the first touch electrode and the second touch electrode.

2. The portable communication device of claim 1 , wherein the first width of the first part or the second width of the second part is configured such that a touch input signal with respect to a region at least partially surrounding the opening is to be compensated by the second part having the second width.

3. The portable communication device of claim 1 , wherein the connection line includes a third part elongated from the first part along at least another part of the boundary of the opening.

4. The portable communication device of claim 3 , wherein the third part has a third width different from the first width and the second width.

5. The portable communication device of claim 4 , wherein the third width is wider than the first width and narrower than the second width.

6. The portable communication device of claim 1 , wherein the second side is opposite to the first side with respect to the boundary of the opening.

7. The portable communication device of claim 1 , wherein at least one part of the first part or the second part is at least partially curved.

8. The portable communication device of claim 7 , wherein the at least one part is at least partially curved as substantially corresponding to a curved shape of the boundary of the opening.

9. The portable communication device of claim 1 , wherein the first touch electrode and the second touch electrode are formed as at least part of a metal mesh.

10. The portable communication device of claim 1 , wherein the second part is composed of a same conductive material as that of the first touch electrode and the second touch electrode.

11. The portable communication device of claim 1 , wherein the touchscreen display includes a printed region surrounding the opening, and wherein the first part and the second part are disposed in the printed region.

12. The portable communication device of claim 11 , wherein the printed region has a curved shape.

13. A portable communication device comprising:
a touchscreen display including a touch sensing layer having an opening formed therein; and
a sensor disposed under the touchscreen display and configured to receive light through the opening,
wherein the touch sensing layer includes:
a first touch electrode disposed at a first side with respect to the opening;
a second touch electrode disposed at a second side different from the first side with respect to the opening; and
a connection line including a first part having a first width and a second part extended from the first part and having a second width wider than the first width, the connection line connecting the first touch electrode and the second touch electrode along at least a part of a boundary of the opening, and

wherein each of the first part and the second part is formed in a curved shape.

14. The portable communication device of claim 13 , wherein the first touch electrode and the second touch electrode are formed as at least part of a metal mesh forming the touch sensing layer.

15. The portable communication device of claim 13 , wherein the first touch electrode and the second touch electrode are formed in a same direction, and the connection line connects the first touch electrode and the second touch electrode in the same direction.

16. The portable communication device of claim 13 , wherein the connection line includes a third part elongated from the connection line along at least a part of the boundary of the opening.

17. The portable communication device of claim 13 , wherein the first width of the first part or the second width of the second part is configured such that a touch input signal with respect to a region at least partially surrounding the opening is to be compensated by the second part having the second width.

18. The portable communication device of claim 13 , wherein the sensor comprises a camera, an illuminance sensor, a proximity sensor or a fingerprint sensor.

19. The portable communication device of claim 13 ,
wherein the touchscreen display includes a printed region surrounding the opening, and
wherein the first part and the second part are disposed in the printed region.

20. The portable communication device of claim 19 , wherein the printed region has a round shape.
