1. A touch module, comprising:
a base substrate;
an array of touch units arranged on the base substrate, each touch unit comprising a first touch electrode extending along a first direction and two second touch electrodes arranged on two sides of the first touch electrode along a second direction, the first direction and the second direction intersecting each other;
wherein the touch unit further comprises: a bridging region between the two second touch electrodes, and a boundary region between the first touch electrode and each of the second touch electrodes; the bridging region comprises a first cutting pattern, the boundary region comprises a second cutting pattern, and the first cutting pattern and the second cutting pattern are substantially the same,
wherein at least one of the first touch electrode and the second touch electrodes further comprises a plurality of third cutting patterns which serve as dummy patterns, and
wherein the first touch electrode and the second touch electrodes are composed of a metal mesh, in the touch unit, cutting openings on the metal mesh that are generated by the plurality of third cutting patterns have a uniform distribution density, the cutting openings refer to openings generated by intersections of the plurality of third cutting patterns with the metal mesh, and the cutting openings extend across multiple sub-pixel patterns within the metal mesh.
