Touch structure, display panel, and electronic device

A touch structure, comprising a first metal grid layer and a second metal grid layer, wherein an insulation layer is between the first metal grid layer and the second metal grid layer, the first metal grid layer comprises a plurality of first metal grids defined by a plurality of first metal lines, and the second metal grid layer comprises a plurality of second metal grids defined by a plurality of second metal lines, shapes of each of the plurality of first metal grids and each of the second metal grids are both polygons;

• the first metal grid layer comprises a plurality of first touch sub-electrodes and a plurality of first connection electrodes 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 are electrically connected in sequence to constitute a first touch electrode extending along the first direction;
• the first metal grid layer further comprises a plurality of second touch sub-electrodes arranged in sequence along the second direction and spaced apart from each other, and the first direction intersects the second direction;
• each of the plurality of first touch sub-electrodes and each of the second touch sub-electrodes are spaced apart from each other, and respectively comprise a plurality of the first metal grids;
• the second metal grid layer comprises a plurality of second connection electrodes spaced apart from each other, each of the plurality of second connection electrodes is electrically connected with adjacent second touch sub-electrodes through a plurality of vias in the insulation layer, so as to electrically connect the adjacent second touch sub electrodes to form a second touch electrode extending in the second direction;
• each of the plurality of second connection electrodes comprises:
• a first metal grid row, comprising a plurality of the second metal grids arranged along the first direction;
• and
• a second metal grid row, adjacent to and connected with the first metal grid row, arranged in the second direction with the first metal grid row, and comprising at least one second metal grid among the plurality of second metal grids arranged along the first direction, wherein a count of the at least one second metal grid in the second metal grid row is less than or equal to a count of the second metal grids in the first metal grid row, and all the second metal lines of the at least one second metal grid in the second metal grid row close to the first metal grid row are sharing second metal lines shared with the second metal grid in the first metal grid row;
• each of the second metal grids comprises at least two vertical edges extending along the second direction, each of the plurality of first touch sub-electrodes is electrically connected with an adjacent first connection electrode through at least one first connection line constituted by a plurality of first metal lines connected end to end in sequence;
• and
• a blank region is between two adjacent first connection lines, and an orthographic projection of the at least two vertical edges of each of the second metal grids on the first metal grid layer is located in the blank region, so that the orthographic projection of the at least two vertical edges of each of the second metal grids on the first metal grid layer does not overlap with the first metal line.
