1. A touch substrate, comprising:
a substrate;
a plurality of first touch electrodes disposed on the substrate, the plurality of first touch electrodes extending in a first direction; and
a plurality of second touch electrodes disposed on the substrate, the plurality of second touch electrodes extending in a second direction intersecting with the first direction, and the plurality of second touch electrodes being insulated from the plurality of first touch electrodes; wherein
each first touch electrode and each second touch electrode both include a mesh structure and a plurality of first dummy electrodes; the mesh structure includes a plurality of first meshes, and each first mesh is provided with at least one first dummy electrode therein, and each first dummy electrode is insulated from a first mesh in which the first dummy electrode is located;
orthogonal projections of the plurality of first touch electrodes on the substrate intersect with orthogonal projections of the plurality of second touch electrodes on the substrate to constitute a plurality of intersection regions; in each intersection region, an orthogonal projection of a mesh structure in a first touch electrode on the substrate and an orthogonal projection of a mesh structure in a second touch electrode on the substrate constitute a projected mesh structure; and
the projected mesh structure has a plurality of second meshes, an orthogonal projection of each first dummy electrode on the substrate is located in a second mesh, and each first dummy electrode includes at least two line segments; the at least two line segments are arranged to intersect, and the at least two line segments have no closed region therebetween.
