Touch panel

A touch panel, comprising:

• a substrate, having a first predetermined number of touch areas, wherein each of the touch areas has a second predetermined number of sub touch areas;
• and
• a touch element, disposed in the first predetermined number of touch areas of the substrate and comprising:
• a plurality of first electrodes, arranged along a first direction in the touch areas, wherein each of the first electrodes comprises a plurality of first electrode patterns;
• a plurality of second electrodes, electrically insulated from the first electrodes and arranged along a second direction intersecting the first direction in the touch areas, wherein each of the second electrodes comprises a plurality of second electrode patterns, and orthographic projections of the first electrode patterns and the second electrode patterns on the substrate have a plurality of gaps therebetween;
• a plurality of third electrodes, electrically insulated from the first electrodes and the second electrodes and disposed in the sub touch areas in a one-to-one manner, wherein each of the third electrodes comprises a plurality of third electrode patterns and a plurality of third connection portions, orthographic projections of the third electrode patterns on the substrate are located in and fill the gaps, and each of the third connection portions electrically insulatingly intersects at least one of the first electrodes or at least one of the second electrodes and is electrically connected with two adjacent third electrode patterns, wherein multiple of the first electrodes arranged along the first direction and corresponding to different sub touch areas are electrically connected, and multiple of the second electrodes arranged along the second direction and corresponding to different sub touch areas are electrically connected;
• and
• the first predetermined number of fourth electrodes, electrically insulated from the first electrodes, the second electrodes and the third electrodes and disposed in the first predetermined number of touch areas in a one-to-one manner, wherein each fourth electrode overlaps the first electrodes, the second electrodes and the third electrodes in the touch area where the fourth electrode is located, and multiple of the third electrodes corresponding to different touch areas are electrically connected.
