Abstract

A touch sensor panel may be provided that includes: a plurality of drive electrodes which extend in a first layer in a first axial direction and sense touch; a plurality of dummy drive electrodes which extend in the first layer in the first axial direction and do not sense the touch; a plurality of receiving electrodes which extend in a second layer in a second axial direction crossing the first axial direction and sense the touch; and a plurality of dummy receiving electrodes which extend in the second layer in the second axial direction and do not sense the touch. A part of a capacitance path between the drive electrode and the receiving electrode is blocked.

Claims (31)

1. A touch sensor panel comprising:

a plurality of drive electrodes which extend in a first layer in a first axial direction and sense touch;

a plurality of dummy drive electrodes which extend in the first layer in the first axial direction and do not sense the touch;

a plurality of receiving electrodes which extend in a second layer in a second axial direction crossing the first axial direction and sense the touch; and

a plurality of dummy receiving electrodes which extend in the second layer in the second axial direction and do not sense the touch,

wherein a part of a capacitance path between the plurality of drive electrodes and the plurality of receiving electrodes is blocked via a deformation of at least one of the plurality of dummy drive electrodes or at least one of the plurality of dummy receiving electrodes,

wherein the deformation includes each of a plurality of dummy drive pads included in each of the plurality of dummy drive electrodes are not formed in an area of the first layer, which corresponds to an outline of each of a plurality of receiving electrode pads included in each of the plurality of receiving electrodes formed in the second layer or,

wherein each of a plurality of dummy receiving pads included in each of the plurality of dummy receiving electrodes are not formed in an area of the second layer, which corresponds to an outline of each of a plurality of drive electrode pads included in each of the plurality of drive electrodes formed in the first layer.

2. The touch sensor panel of claim 1 ,

wherein the plurality of dummy receiving electrodes are arranged at a position opposite to a position where the plurality of drive electrodes are arranged,

wherein the plurality of dummy drive electrodes are arranged at a position opposite to a position where the plurality of receiving electrodes are arranged.

3. The touch sensor panel of claim 2 , wherein each of the plurality of dummy drive pads include pad parts which are spaced apart from each other around an outline of each of the plurality of receiving electrode pads.

4. The touch sensor panel of claim 3 , wherein each of the plurality of dummy drive pads include a first pad which is arranged at a center of a position opposite to a position where each of the plurality of receiving electrode pads are arranged, a second pad which is arranged at a position surrounding the first pad, a third pad which is arranged at a position surrounding the second pad, and a fourth pad which is arranged at a position outside each of the receiving electrode pads, and

wherein the third pad and the fourth pad are spaced apart from each other around an outline of each of the plurality of receiving electrode pads.

5. The touch sensor panel of claim 1 , wherein each of the plurality of dummy receiving pads include pad parts which are spaced apart from each other around outline of each of the plurality of drive electrode pads.

6. The touch sensor panel of claim 5 , wherein each of the plurality of dummy receiving pads include a first pad which is arranged at a center of a position opposite to a position where each of the plurality of drive electrode pads are arranged and a second pad which is arranged at a position outside each of the drive electrode pads, and

wherein the first pad and the second pad are spaced apart from each other around an outline of each of the plurality of drive electrode pads.

7. The touch sensor panel of claim 1 , wherein the at least one of the plurality of dummy drive electrodes are deformed by cutting a portion of the at least one of the plurality of dummy drive electrodes.

8. The touch sensor panel of claim 1 , wherein the at least one of the plurality of dummy drive electrodes are deformed by cutting the at least one of the plurality of dummy drive electrodes along an outline of a receiving electrode.

9. A touch sensor panel comprising:

a plurality of drive electrodes which extend in a first layer in a first axial direction;

a plurality of dummy drive electrodes which extend in the first layer in the first axial direction;

a plurality of receiving electrodes which extend in a second layer in a second axial direction crossing the first axial direction; and

a plurality of dummy receiving electrodes which extend in the second layer in the second axial direction,

wherein a part of a capacitance path between the plurality of drive electrodes and the plurality of receiving electrodes is blocked via a deformation of at least one of the plurality of dummy drive electrodes, and

wherein each of a plurality of dummy drive pads included in each of the plurality of dummy drive electrodes are not formed in an area of the first layer, which corresponds to an outline of each of a plurality of receiving electrode pads included in each of the plurality of receiving electrodes formed in the second layer, or each of a plurality of dummy receiving pads included in each of the plurality of dummy receiving electrodes are not formed in an area of the second layer, which corresponds to an outline of each of a plurality of drive electrode pads included in each of the plurality of drive electrodes formed in the first layer.

10. The touch sensor panel of claim 9 ,

wherein the plurality of dummy receiving electrodes are arranged at a position opposite to a position where the plurality of drive electrodes are arranged,

wherein the plurality of dummy drive electrodes are arranged at a position opposite to a position where the plurality of receiving electrodes are arranged,

and wherein a dummy drive electrode is not formed in an area of the first layer, which corresponds to an outline of each of a plurality of receiving electrode pads included in each of the plurality of receiving electrodes formed in the second layer.

11. The touch sensor panel of claim 10 , wherein each of a plurality of dummy drive pads included in each of the plurality of dummy drive electrodes include pad parts which are spaced apart from each other around an outline of each of the plurality of receiving electrode pads.
