Touch control structure, touch display panel and electronic device

A touch display panel, comprising:

• a base substrate;
• a display structure and a touch control structure that are sequentially stacked on the base substrate, wherein
• the display structure comprises a planarization layer,
• the touch control structure comprises a first metal layer, an insulation layer and a second metal layer that are sequentially stacked on the display structure,
• 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, 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, an orthographic projection of an edge of the planarization layer on the base substrate intersects with both an orthographic projection of the first detection line and an orthographic projection of the second detection line on the base substrate;
• the first detection line is arranged in the second metal layer, and 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, the first detection part is electrically connected with the second detection part through a first via structure penetrating through the insulation layer, and an orthographic projection of the overlapping part of the second detection line on the base substrate overlaps with an orthographic projection of the edge of the planarization layer on the base substrate;
• 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 touch region is provided with a first touch electrode and a second touch electrode that are spaced apart from each other;
• a first touch electrode lead wire and a second touch electrode lead wire are arranged on a side of the common signal line close to the touch region, and the first touch electrode lead wire is electrically connected with the first touch electrode, and the second touch electrode lead wire is electrically connected with the second touch electrode;
• two adjacent first touch electrode lead wires in an extension direction of the first touch electrode lead wire are electrically connected through a first connection line, and two adjacent second touch electrode lead wires in an extension direction of the second touch electrode lead wire are electrically connected through a second connection line, one of the first connection line and the second connection line is only arranged in the first metal layer, and other one of the first connection line and the second connection line is only arranged in the second metal layer, and an orthographic projection of the first connection line on the base substrate at least partially overlaps with of an orthographic projection of the second connection line on the base substrate.
