1. A touch control structure comprising:
a base substrate;
a first metal layer, an insulation layer and a second metal layer that are sequentially stacked on the base substrate, wherein
on a plane parallel to a main surface of the base substrate, the touch control structure is divided into a touch region and a peripheral region surrounding the touch region, and along a direction from the touch region to the peripheral region, the peripheral region comprises a first detection line and a second detection line that are sequentially arranged and spaced apart from each other;
the first detection line is arranged in the second metal layer, an overlapping part of the second detection line is arranged in the first metal layer, a first end of the second detection line comprises a first detection part arranged in the second metal layer and a second detection part arranged in the first metal layer, and the first detection part is electrically connected with the second detection part through a first via structure penetrating through the insulation layer;
the touch control structure further comprises a common signal line on a side of the first detection line close to the touch region, and the common signal line comprises a first sub-common signal line and a second sub-common signal line that are stacked, the first sub-common signal line is in the first metal layer, the second sub-common signal line is in the second metal layer, the first sub-common signal line is electrically connected with the second sub-common signal line through a second via structure which is in the insulation layer.
