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. An apparatus comprising:
a touchscreen display including a touch layer having an opening formed therein; and
a sensor disposed under and at least partially aligned with the opening,
wherein the touch layer includes:
a first set of touch lines including a first touch line, and the first set of touch lines forming at least part of a first set of touch electrodes arranged in a first direction, and
a second set of touch lines including a second touch line, and the second set of touch lines forming at least part of a second set of touch electrodes arranged in a second direction substantially perpendicular to the first direction,

wherein the first touch line forms at least part of a first touch electrode disposed in a first side with respect to the opening and a second touch electrode disposed in a second side opposite to the first side with respect to the opening, the first touch line including a first part having a first width and a second part having a second width wider than the first width, the first part and the second part connecting the first touch electrode and the second touch electrode along at least a part of an outer boundary of the opening, and
wherein the second touch line forms at least part of a third touch electrode disposed in a third side with respect to the opening and a fourth touch electrode disposed in a fourth side opposite to the third side with respect to the opening, the second touch line including a third part having a third width and a fourth part having a fourth width wider than the third width, the third part and the fourth part connecting the third touch electrode and the fourth touch electrode along at least another part of the outer boundary of the opening.

2. The apparatus of claim 1 , wherein the first width of the first part and the second width of the second part are configured such that a touch input with respect to a region at least partially surrounding the opening is to be compensated by the second width of the second part.

3. The apparatus of claim 1 , wherein the third width of the third part and the fourth width of the fourth part are configured such that a touch input with respect to a region at least partially surrounding the opening is to be compensated by the fourth width of the fourth part.

4. The apparatus of claim 1 ,
wherein the first touch line further includes a fifth part extending from the first part along the outer boundary of the opening, and
wherein the second touch line further includes a sixth part extending from the third part along the outer boundary of the opening.

5. The apparatus of claim 1 , wherein the first part, the second part, the third part, and the fourth part comprise at least one of a metal or a metal mesh.

6. The apparatus of claim 1 , wherein the first touch electrode, the second touch electrode, the third touch electrode, and the fourth touch electrode comprise at least one of a metal or a metal mesh.

7. The apparatus of claim 1 ,
wherein the touch layer comprises a printing region surrounding the opening, and
wherein the first part, the second part, the third part, and the fourth part are disposed in the printing region.

8. The apparatus of claim 7 , wherein the printing region has a round shape.

9. The apparatus of claim 1 ,
wherein the touchscreen display includes a display panel, and
wherein the touch layer is formed in a same layer as the display panel.

10. An apparatus comprising:
an optical sensor; and
a touchscreen display having an opening formed therein and partially aligned with the optical sensor, the touchscreen display including:
a first touch line circumventing along a first portion of a boundary of the opening, the first touch line forming at least part of a first touch electrode and a second touch electrode arranged in a first direction, the first touch electrode disposed in a first side with respect to the opening, and the second touch electrode disposed in a second side with respect to the opening opposite to the first side, the first touch line including a first part having a first width and a second part having a second width wider than the first width, the first part and the second part disposed along the first portion of the boundary of the opening and connecting the first touch electrode and the second touch electrode, and
a second touch line circumventing along a second portion of the boundary of the opening, the second touch line forming at least part of a third touch electrode and a fourth touch electrode arranged in a second direction substantially perpendicular to the first direction, the third touch electrode disposed in a third side with respect to the opening, and the fourth touch electrode disposed in a fourth side with respect to the opening opposite to the third side, the second touch line including a third part having a third width and a fourth part having a fourth width wider than the third width, the third part and the fourth part disposed along the second portion of the boundary of the opening and connecting the third touch electrode and the fourth touch electrode.

11. The apparatus of claim 10 , wherein the touchscreen display includes:
a third touch line adjacent to the first touch line and formed as substantially straight, the third touch line including a fifth touch electrode and a sixth touch electrode arranged in the first direction; and
a fourth touch line adjacent to the second touch line and formed as substantially straight, the fourth touch line including a seventh touch electrode and an eighth touch electrode arranged in the second direction.

12. The apparatus of claim 10 , wherein the optical sensor forms at least part of a camera.

13. The apparatus of claim 10 , wherein the first width of the first part and the second width of the second part are configured such that a touch input with respect to a region at least partially surrounding the opening is to be compensated by the second width of the second part.

14. The apparatus of claim 10 , wherein the third width of the third part and the fourth width of the fourth part are configured such that a touch input with respect to a region at least partially surrounding the opening is to be compensated by the fourth width of the fourth part.

15. The apparatus of claim 10 , wherein the first part, the second part, the third part, and the fourth part comprise at least one of a metal or a metal mesh.

16. The apparatus of claim 10 , wherein the first touch electrode, the second touch electrode, the third touch electrode, and the fourth touch electrode comprise at least one of a metal or a metal mesh.

17. The apparatus of claim 10 ,
wherein the touchscreen display comprises a printing region surrounding the opening, and
wherein the first part, the second part, the third part, and the fourth part are disposed in the printing region.
