Method for forming metal mesh pattern and touch panel

A method for forming a metal mesh pattern on a corresponding display panel, the method comprising:

• defining a mesh base of the metal mesh pattern and the mesh base consisting of a plurality of mesh base units;
• determining at least one pitch of each mesh base unit of the mesh base, wherein a ratio of the pitch of each mesh base unit to a side length of a sub-pixel of the corresponding display panel ranges from 1.05 to 1.2 or 1.5 to 1.7;
• setting a seed region and an non-seed region within each mesh base unit;
• within each mesh base unit, generating a plurality of seeds by randomly selecting a point in the seed region and generating no seed in the non-seed region, wherein the plurality of seeds do not occupy the whole area of the seed region, a ratio of an area of the seed region to an area of each mesh base unit is a constant;
• and
• forming the metal mesh pattern, wherein the metal mesh pattern consisting of perpendicular bisectors of lines interconnecting between any immediately-adjacent two of the plurality of seeds.
