Touch sensor and display apparatus

A touch sensor, comprising:

• a first opening region, a plurality of first touch electrodes, a plurality of second touch electrodes and a plurality of first connecting sub-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;
• adjacent second touch sub-electrodes in the first region are electrically connected via a corresponding first number of first connecting sub-electrode;
• and
• adjacent second touch sub-electrodes in the third region are electrically connected via a corresponding second number of first connecting sub-electrode, and the second number is greater than the first number.
