1. A touch substrate, comprising:
a touch insulating layer;
a touch electrode at a side of the touch insulating layer; and
a first floating electrode at a side of the touch insulating layer away from the touch electrode, wherein the first floating electrode and the touch electrode at least partially overlap in a thickness direction of the touch insulating layer;
wherein the first floating electrode is not grounded or is not connected to a fixed power signal; and
wherein the touch electrode comprises a first electrode strip and a second electrode strip arranged in a cross manner, the first electrode strip extends along a first direction, the second electrode strip extends along a second direction, and the first direction and the second direction are different;
first protrusions spaced are provided in a width direction of the first electrode strip, and a first concave part is formed between every two adjacent first protrusions of the first protrusions; an extension part is arranged in a width direction of the second electrode strip, and the extension part extends along the first direction, and second protrusions are provided in a width direction of the extension part, and the second protrusions extend into the first concave parts respectively.
