Touch control structure, touch display panel and electronic device

A touch control structure comprising:

• a base substrate;
• a first metal layer and a second metal layer stacked on the base substrate, and an insulating layer sandwiched between the first metal layer and the second metal layer,
• wherein the first metal layer comprises a plurality of first touch sub-electrodes sequentially arranged along a first direction and spaced apart from each other, and a plurality of second touch sub-electrodes and a plurality of connection electrodes which are sequentially arranged along a second direction, the first direction intersects with the second direction and the plurality of first touch sub-electrodes and the plurality of second touch sub-electrodes are spaced apart from each other;
• the second metal layer comprises a plurality of bridge electrodes spaced apart from each other, and each of the plurality of bridge electrodes is electrically connected with two adjacent first touch sub-electrodes through a plurality of via structures in the insulating layer, so as to electrically connect any adjacent first touch sub-electrodes to form a first touch electrode extending in the first direction;
• the plurality of second touch sub-electrodes and the plurality of connection electrodes are alternately arranged one by one and electrically connected in sequence to form a second touch electrode extending along the second direction;
• an orthographic projection of each of the plurality of bridge electrodes on the base substrate is overlapped with an orthographic projection of a corresponding connection electrode on the base substrate;
• on a plane parallel to the main surface of the base substrate, the touch control structure is divided into a middle area and a peripheral area surrounding the middle area, at least in the middle area, the plurality of bridge electrodes comprise a first bridge electrode and a second bridge electrode which are adjacent to each other, and the two adjacent first touch sub-electrodes connected with the first bridge electrode are a first group of touch sub-electrodes, the two adjacent first touch sub-electrodes connected with the second bridge electrode are a second group of touch sub-electrodes, the first group of touch sub-electrodes and the second group of touch sub-electrodes are different touch sub-electrodes, a same side of the peripheral area comprises one bridge electrode, the bridge electrode is a third bridge electrode, and extension directions of the first bridge electrode and the second bridge electrode which are adjacent to each other are different, and an extension direction of the third bridge electrode is the same as an extension direction of a bridge electrode which is closest to the third bridge electrode in the middle area.
