1. A touch control structure, comprising a plurality of touch electrodes in a touch control area and a plurality of touch signal lines in a peripheral area;
wherein a respective one of the plurality of touch signal lines comprises a double-layer structure in a double-layer region and a single-layer structure in a single-layer region;
the peripheral area comprises a first sub-area exclusively on a first side of the touch control area, a second sub-area exclusively on a second side of the touch control area, a third sub-area exclusively on a third side of the touch control area, a fourth sub-area exclusively on a fourth side of the touch control area;
the first sub-area comprises a side region, and one or more corner regions respectively at one or more corners of the touch control structure;
wherein the double-layer region and the single-layer region are in the first sub-area, the first sub-area has a first shortest width along a direction from the touch control area to the first sub-area, the first shortest width is greater than a shortest width of at least one of sub-areas of the peripheral area other than the first sub-area;
a plurality of adjacent double-layer structures in the double-layer region are respectively connected to a plurality of adjacent single-layer structures in the single-layer region;
at least two of the plurality of adjacent single-layer structures are respectively in a first layer and a second layer; and
the touch control structure further comprises a touch insulating layer between the first layer and the second layer;
wherein the first side and the fourth side are two opposite sides of the touch control area;
the second side and the third side are another two opposite sides of the touch control area;
the double-layer region and the single-layer region are exclusively on the first side of the touch control area;
the single-layer region is in the side region, which is a continuous region; and
a region where the double-layer structure transitions to the single-layer structure is at least partially in the one or more corner regions.
