1. A touch substrate, having a touch electrode area and a peripheral area surrounding the touch electrode area, and comprising:
a first touch electrode layer in the touch electrode area, the first touch electrode layer comprising first touch electrodes and first dummy electrodes alternately arranged along a first direction and separated from each other, wherein the first touch electrodes and the first dummy electrodes extend along a second direction intersecting the first direction, the first touch electrodes and the first dummy electrodes both are conductive mesh structures, and the first dummy electrode has a first end and a second end along the second direction and comprises at least one conductive path that is continuous between the first end and the second end; and
an electrostatic release structure in the peripheral area, the at least one conductive path being electrically connected to the electrostatic release structure through one of the first end and the second end of the first dummy electrode,
wherein the touch substrate further comprises a second touch electrode layer insulated from and stacked with the first touch electrode layer in the touch electrode area, and a second connection part in the peripheral area; and
the second touch electrode layer comprises second touch electrodes and second dummy electrodes alternately arranged along the second direction and separated from each other, the second touch electrodes and the second dummy electrodes extend along the first direction, the second touch electrodes and the second dummy electrodes both are conductive mesh structures, and the second dummy electrode has a third end and a fourth end along the first direction and comprises at least one conductive path that is continuous between the third end and the fourth end and is electrically connected to the electrostatic release structure.
