Claim 17:
18. A touch sensor, comprising: a first opening region, a plurality of first touch electrodes and a plurality of second touch electrodes,
wherein a center of the first opening region and a center of the touch sensor do not coincide;
the plurality of first touch electrodes respectively extend along a first direction, and at least one of the plurality of first touch electrodes comprises a plurality of first touch sub-electrodes arranged side by side in the first direction and electrically connected with each other;
the plurality of second touch electrodes respectively extend along a second direction intersecting with the first direction, and at least one of the plurality of second touch electrodes comprises a plurality of second touch sub-electrodes arranged side by side in the second direction and electrically connected with each other;
the plurality of first touch electrodes are arranged side by side along the second direction, and the plurality of second touch electrodes are arranged side by side along the first direction; and
the plurality of first touch sub-electrodes and the plurality of second touch sub-electrodes together at least partially surround the first opening region;
the touch sensor has a first region, a second region and a third region which are sequentially laid out in the second direction,
the first opening region is positioned in the second region; and
an area of a first touch sub-electrode in the first region is less than that of a first touch sub-electrode in the third region, or an area of a second touch sub-electrode in the first region is less than that of a second touch sub-electrode in the third region;
the touch sensor further comprises a plurality of dummy electrodes,
at least one of the plurality of dummy electrodes is arranged between the first touch sub-electrode and the second touch sub-electrode that are adjacent; and
a number of the dummy electrodes between the first touch sub-electrode and the second touch sub-electrode that are adjacent in the first region is less than a number of the dummy electrodes between the first touch sub-electrode and the second touch sub-electrode that are adjacent in the third region.
