1. A touch-control structure, wherein the touch-control structure is provided with a touch-control region and a peripheral region outside the touch-control region, the peripheral region comprises an edge region surrounding the touch-control region and a lead-out region extending outward from a part of the edge region, and the lead-out region is provided with a binding portion; the touch-control structure comprises touch-control electrodes located in the touch-control region and lead wires located in the peripheral region, and the touch-control electrodes are connected to the binding portion through the lead wires;
the touch-control electrodes comprise a plurality of first touch-control electrodes and a plurality of second touch-control electrodes; the first touch-control electrodes extend along a first direction and are distributed at intervals along a second direction;
the second touch-control electrodes extend along the second direction and are distributed at intervals along the first direction; the first direction is intersected with the second direction; the first touch-control electrodes are insulated from the second touch-control electrodes; the lead wires comprise a plurality of first lead wires and a plurality of second lead wires; the first touch-control electrodes are connected to the binding portion through the first lead wires, and the second touch-control electrodes are connected to the binding portion through the second lead wires;
at least a part of the first lead wires comprises main body portions and narrowing portions connected to each other along an extension path of the first lead wires, and a cross section of at least a part of the narrowing portions is smaller than a cross section of the main body portions;
wherein the lead wires comprise a plurality of layers of wire bodies provided at intervals, and the wire bodies of a same lead wire overlap with each other;
a part of the wire bodies of at least a part of the first lead wires is provided with a fracture;
wire bodies cut off by the fracture comprises a plurality of wire segments separated by the fracture, and the wire segments are all connected to adjacent wire bodies through contact holes, so as to connect the wire bodies cut off by the fracture to adjacent wire bodies in parallel;
a part of the first lead wires corresponding to the wire segments is the main body portions; and
a part of the first lead wires between two contact holes connected to two ends of a same fracture is the narrowing portions.
