1. A touch panel having a touch area, the touch panel comprising:
a base substrate; and
a touch function layer disposed on the base substrate, the touch function layer including a plurality of first touch units extending in a first direction and a plurality of second touch units extending in a second direction; each first touch unit including a plurality of first touch electrodes arranged in the first direction and connected in series, each second touch unit including a plurality of second touch electrodes arranged in the second direction and connected in series; the first touch electrodes and the second touch electrodes being insulated from each other; the first direction intersecting the second direction;
wherein the base substrate has at least two mounting holes located in the touch area, the touch function layer is hollowed out at positions corresponding to the at least two mounting holes and has a gap region at a position corresponding to a region between two adjacent mounting holes; in a first touch unit passing through the gap region, first touch electrodes located in the gap region serve as a first gap electrode and a second gap electrode that are arranged in the first direction and are electrically connected to each other; in a second touch unit passing through the gap region, second touch electrodes located in the gap region serve as a third gap electrode and a fourth gap electrode that are arranged in the second direction and are electrically connected to each other; the third gap electrode is located between the first gap electrode and the second gap electrode in the first direction,
wherein an edge of at least one of the third gap electrode or the fourth gap electrode has at least one branch, the edge is proximate to at least one of the first gap electrode or the second gap electrode, and the at least one branch extends into the at least one of the first gap electrode or the second gap electrode; or
wherein an edge of at least one of the third gap electrode or the fourth gap electrode has at least one branch, the edge is proximate to at least one of the first gap electrode or the second gap electrode, the at least one branch extends into the at least one of the first gap electrode or the second gap electrode, and an edge of the branch is zigzag-shaped.
