1. A touch module, comprising:
a base substrate; and
a plurality of touch electrodes on the base substrate; wherein
the plurality of touch electrodes comprise a plurality of first touch electrodes extending along a first direction and a plurality of second touch electrodes extending along a second direction;
each of the plurality of first touch electrodes comprises a plurality of first electrode blocks and a plurality of second electrode blocks, and each of the plurality of second touch electrodes comprises a plurality of third electrode blocks and a plurality of fourth electrode blocks;
in a same one of the plurality of first touch electrodes,
the plurality of first electrode blocks are arranged in sequence along the first direction;
each of the plurality of second electrode blocks is located in an area where a third electrode block adjacent to the plurality of first electrode blocks are located;
the plurality of second electrode blocks and the plurality of third electrode blocks are insulated from each other; and
the plurality of third electrode blocks each has a first hollow region in an area corresponding to a second electrode block, and an orthographic projection of the first hollow region on the base substrate is larger than an orthographic projection of the second electrode block on the base substrate;
and
in a same one of the second touch electrodes,
the plurality of third electrode blocks are arranged in sequence along the second direction;
each of the plurality of fourth electrode blocks is located in an area where a first electrode block adjacent to the plurality of third electrode blocks are located;
the plurality of fourth electrode blocks and the plurality of first electrode blocks are insulated from each other; and
the plurality of first electrode blocks each has a second hollow region in an area corresponding to a fourth electrode block, and an orthographic projection of the second hollow region on the base substrate is larger than an orthographic projection of the fourth electrode block on the base substrate.
