Touch structure, display panel and electronic device

A touch structure, comprising:

• a plurality of touch sub-electrodes spaced apart from each other;
• and
• a dummy electrode embedded in at least one touch sub-electrode of the plurality of touch sub-electrodes and spaced apart from the touch sub-electrode in which the dummy electrode is embedded to insulate each other, wherein the at least one touch sub-electrode comprises a channel and a main body part surrounding the dummy electrode and the channel, and the strip-shaped channel passes through the dummy electrode, and both two ends of the strip-shaped channel in an extension direction of the strip-shaped channel are connected with the main body part;
• the touch structure comprises a first electrode layer and a second electrode layer, and an insulation layer is provided between the first electrode layer and the second electrode layer;
• the plurality of touch sub-electrodes comprise a plurality of first touch sub-electrodes and a plurality of second touch sub-electrodes, and the touch structure further comprises a plurality of first connection electrodes and a plurality of second connection electrodes;
• the plurality of first touch sub-electrodes and the plurality of first connection electrodes are all in the first electrode layer and arranged along a first direction, the plurality of first touch sub-electrodes and the plurality of first connection electrodes are alternately distributed one by one and electrically connected in sequence to constitute a first touch electrode extending along the first direction;
• the plurality of second touch sub-electrodes are in the first electrode layer, and are arranged in sequence along a second direction and spaced apart from each other, the first direction intersects the second direction, and each of the plurality of first touch sub-electrodes and each of the second touch sub-electrodes are spaced apart from each other;
• the plurality of second connection electrodes are in the second electrode layer and are spaced apart from each other, and each of the plurality of second connection electrodes is electrically connected with adjacent second touch sub-electrodes through vias in the insulation layer, so as to electrically connect the adjacent second touch sub-electrodes to constitute a second touch electrode extending in the second direction;
• the dummy electrode is in the first electrode layer and is embedded in the first touch sub-electrode and/or embedded in the second touch sub-electrode.
