Claim 1:
2. A touch structure, comprising a first metal mesh layer and a second metal mesh layer,
wherein the first metal mesh layer and the second metal mesh layer are spaced apart through an insulation layer between the first metal mesh layer and the second metal mesh layer, the first metal mesh layer comprises a plurality of first metal meshes defined by a plurality of first metal lines, the second metal mesh layer comprises a plurality of second metal meshes defined by a plurality of second metal lines, and each of the plurality of first metal meshes and each of the plurality of second metal meshes are polygonal;
the first metal mesh layer comprises a plurality of first touch sub-electrodes and a plurality of first connection electrodes arranged along a first direction, and 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 form a first touch electrode extended along the first direction;
the first metal mesh layer further comprises a plurality of second touch sub-electrodes arranged sequentially along a second direction and spaced apart from each other, and the first direction intersects with the second direction;
each of the plurality of first touch sub-electrodes is spaced apart from each of the second touch sub-electrodes, and each of the plurality of first touch sub-electrodes and each of the second touch sub-electrodes respectively comprise multiple first metal meshes;
the second metal mesh layer comprises a plurality of second connection electrodes spaced apart from each other, and each of the plurality of second connection electrodes is electrically connected to an adjacent second touch sub-electrode through multiple via holes in the insulation layer, thereby electrically connecting adjacent second touch sub-electrodes to form a second touch electrode extended along the second direction;
orthographic projections of first metal lines of at least two first metal meshes of the second touch sub-electrode on the second metal mesh layer are respectively overlapped with second metal lines of at least two second metal meshes of a corresponding second connection electrode, so that the at least two first metal meshes comprise a plurality of vertices overlapping with the at least two second metal meshes, the plurality of vertices comprise multiple connection vertices, and the multiple via holes are respectively disposed at the multiple connection vertices in one-to-one correspondence;
at most one of vertices adjacent to each of the multiple connection vertices is a connection vertex;
a plurality of first metal lines in a boundary region between adjacent first touch sub-electrode and second touch electrode respectively comprise a plurality of spaces; and
each of the plurality of spaces divides a first metal line, where the each space is located, into two first metal line segments; one of the two first metal line segments belongs to the first touch sub-electrode, and the other one of the two first metal line segments belongs to the second touch sub-electrode, so that the adjacent first touch sub-electrode and second touch sub-electrode are insulated.
