1. A touch-control panel, comprising:
a substrate and a touch-control sensing layer located on the substrate, wherein:
the touch-control sensing layer comprises a plurality of touch-control units, each of the touch-control units comprises at least one touch-control pattern, the touch-control pattern comprises a first touch-control electrode, and a second touch-control electrode that are insulated from each other;
the first touch-control electrode has at least one group of first touch-control group, and the first touch-control group comprises a plurality of first touch-control branches and first conductive connection portions connected to one end of the plurality of first touch-control branches;
the second touch-control electrode has at least one group of second touch-control group, the second touch-control group comprises a plurality of second touch-control branches and second conductive connection portions connected to one end of the plurality of second touch-control branches, and the second touch-control branches and the first touch-control branches are arranged alternately in a first direction and are spaced apart from each other;
at least one of surfaces of the first touch-control branches opposite to the second touch-control branches are wave-shaped surfaces, and surfaces of the second touch-control branches opposite to the first touch-control branches are wave-shaped surfaces;
the wave-shaped surface is formed by splicing a plurality of tooth portions arranged in a second direction, and the second direction intersects with the first direction;
the tooth portion is triangular, and an included angle between a side surface of the tooth portion and a plane where the first direction is located is 5° to 95°;
the touch-control unit has a first center line extending in the first direction and a second center line extending in a second direction, the second direction and the first direction are perpendicular to each other; and a plurality of the touch-control patterns are provided in the touch-control unit, and the touch-control units are arranged in a mirror image with respect to at least one of the first center line and the second center line;
four touch-control patterns are provided in the touch-control unit, and the four touch-control patterns are arranged in an array in the first direction and the second direction; adjacent touch-control patterns in the first direction share the first touch-control branch located at an edge, and the first touch-control branches located at the edge of the adjacent touch-control patterns in the second direction are directly connected, adjacent touch-control patterns in the second direction share the second conductive connection portion, and the second conductive connection portions between adjacent touch-control patterns in the first direction are connected through a conductive bridge, and the conductive bridge and the first touch-control electrode are insulated from each other; and
the touch-control unit is arranged in a mirror image with respect to the first center line, and each touch-control pattern further comprises a second dummy electrode insulated from the first touch-control electrode and the second touch-control electrode, and the second dummy electrode is located in an edge region of the touch-control pattern away from the second center line.
