1. A touch structure, comprising:
a metal mesh, comprising a plurality of metal wires;
wherein the metal mesh has a plurality of opening units, each of the opening units comprises at least three openings, each of the openings is enclosed by a plurality of metal wires, and the plurality of metal wires enclosing each of the openings have at least three different extending directions; at least one of the metal wires separating the openings in the opening unit and each of the metal wires forming an outer boundary of the opening unit have different extending directions;
wherein the metal wires forming the outer boundary of the opening unit at least comprise one pair of metal wires with a same extending direction;
the outer boundary of the opening unit is a hexagon with opposite sides parallel, and the metal wires forming the outer boundary of the opening unit comprise:
two first metal wires arranged oppositely and in parallel;
two second metal wires arranged oppositely and in parallel; and
two third metal wires arranged oppositely and in parallel;
wherein one of the two second metal wires connects one of the two first metal wires and one of the two third metal wires, and other one of the two second metal wires connects other one of the two first metal wires and other one of the two third metal wires;
wherein a length of the third metal wire is greater than a length of the first metal wire;
the length of the first metal wire is greater than a length of the second metal wire; and
the second metal wire is perpendicular to the third metal wire connected with the second metal wire;
wherein in the opening unit, a first included angle formed between the first metal wire and the second metal wire connected with the first metal wire is same as a second included angle formed between the first metal wire and the third metal wire connected with the first metal wire.
