1. A touch sensor, comprising: a first opening region, a plurality of first touch electrodes and a plurality of second touch electrodes, wherein
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
an entirety constituted by the plurality of first touch sub-electrodes and the plurality of second touch sub-electrodes surrounds at least a part of 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, two edges of the first region that are arranged in the second direction respectively coincide with an upper boundary of the touch sensor and an upper boundary of the second region, two edges of the third region that are arranged in the second direction respectively coincide with a lower boundary of the second region and a lower boundary of the touch sensor, and a size of an entirety of the third region in the second direction is greater than that of an entirety of the first region;
the first opening region is positioned in the second region;
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; and
a distance between two adjacent second touch sub-electrodes in the first region in the second direction is less than a distance between two adjacent second touch sub-electrodes in the third region in the second direction
wherein an overall width of the touch sensor in the second direction is greater than the overall width of the touch sensor in the first direction.
