1. An array substrate, comprising:
a substrate;
a plurality of touch electrodes located at a side of the substrate, and the plurality of touch electrodes comprising a first touch electrode; and
a plurality of touch leads located at the side of the substrate and each extending along a first direction,
wherein the first touch electrode comprises a plurality of grooves and a plurality of first portions, each of the plurality of grooves is a non-physical structure of the first touch electrode, and each of the plurality of first portions is a physical structure of the first touch electrode; the plurality of grooves are arranged in an array along the first direction and a second direction intersecting with the first direction, and one of the plurality of first portions refers to all of the physical structure of the first touch electrode between any two adjacent grooves of the plurality of grooves along the first direction;
wherein the plurality of touch leads comprises a first touch lead and a second touch lead and each of the first touch lead and the second touch lead is composed of first line segments and second line segments alternately arranged along the first direction;
wherein along a direction perpendicular to a plane of the substrate, the first touch lead and the second touch lead overlap the first touch electrode, respectively, one of the first line segments overlaps a corresponding one of the plurality of first portions, and one of the second line segments overlaps a corresponding one of the plurality of grooves;
wherein in the first touch lead, along the second direction, a line width of each of the first line segments is at least partially smaller than a line width of one of the second line segments adjacent thereto, and is entirely not greater than the line width of the second line segment adjacent thereto; and
wherein in the second touch lead, along the second direction, a line width of each of the first line segments is entirely equal to the line width of the second line segment adjacent thereto.
