Abstract
A touch structure, a touch display panel and an electronic device are provided. The touch structure includes a first metal mesh layer and a second metal mesh layer, the first metal mesh layer includes a first touch electrode and second touch sub-electrodes, the second metal mesh layer includes second connection electrodes spaced apart from each other, and each of the second connection electrodes is electrically connected with an adjacent second touch sub-electrode through via holes in the insulation layer. At least two first metal meshes of the second touch sub-electrodes include multiple vertices overlapping with at least two second metal meshes of the second connection electrodes, the multiple vertices include connection vertices, and the via holes are respectively disposed at the connection vertices; at most one of vertices adjacent to each connection vertex is a connection vertex. The touch structure can effectively reduce capacitance load on the touch electrodes.
