1. A touch substrate, comprising a plurality of touch units and each touch unit comprising:
a first electrode extending along a first direction and comprising:
a first trunk electrode parallel to the first direction;
a plurality of first branch electrodes disposed on two sides of the first trunk electrode; the first branch electrodes extending outwardly with the first trunk electrode as a center to form a radial structure; and
first dry electrodes disposed on the two sides of the first trunk electrode and connected to the first trunk electrode, wherein the first branch electrodes are disposed on one side of the first dry electrodes away from the first trunk electrode and connected to the first dry electrode, and the first branch electrode defines a second included angle being less than 90° and greater than 0° with the first trunk electrode; and wherein each of the first dry electrodes comprises at least two first sub-dry electrodes, every two first sub-dry electrodes are connected to each other and surround with the first trunk electrode to define an opening, and each of the first sub-dry electrodes defines a first included angle being less than 90° and greater than 0° with the first trunk electrode; and
a second electrode extending along a second direction perpendicular to the first direction and comprising:
a second trunk electrode parallel to the second direction; and
a plurality of second branch electrodes disposed on two sides of the second trunk electrode;
wherein the first branch electrodes and the second branch electrodes are alternately disposed to form an occlusal structure.
