1. A touch substrate, comprising:
a base substrate;
a conductive layer on the base substrate, the conductive layer being a single-layer structure, and the conductive layer comprising a plurality of touch electrodes and a plurality of leads electrically connected with the plurality of touch electrodes; wherein:
a first grid-like structure is formed between adjacent leads, and a first disconnection line is arranged between the adjacent leads in the first grid-like structure;
the touch electrodes have a second grid-like structure, and the second grid-like structure comprises a plurality of breakpoints; and
a connection line between the plurality of breakpoints has a substantially same shape as the first disconnection line;
wherein the first disconnection line between the adjacent leads in the first grid-like structure is a first fold line;
the connection line between the breakpoints in the second grid-like structure is a second fold line; and
the first fold line and the second fold line have a substantially same shape.
