Metal mesh assembly, touch control display panel and manufacturing thereof, and display apparatus

A metal mesh assembly, comprising a plurality of composite pattern units, each formed by a plurality of metal lines and having two substantially perpendicular symmetric axes, wherein the plurality of metal lines comprise:

• a plurality of driving lines, in a driving layer;
• and
• a plurality of sensing lines, in a sensing layer insulated from the driving layer;
• wherein:
• the plurality of driving lines and the plurality of sensing lines compositely form each of the plurality of composite pattern units;
• each of the plurality of driving lines and the plurality of sensing lines have a pattern with the two substantially perpendicular symmetric axes;
• the plurality of metal lines further comprise a plurality of dummy lines, arranged in at least one of a dummy layer, the driving layer and the sensing layer;
• the plurality of dummy lines, along with the plurality of driving lines and the plurality of sensing lines, compositely form each of the plurality of composite pattern units;
• the plurality of dummy lines have a pattern with the two substantially perpendicular symmetric axes;
• and
• each of the plurality of composite pattern units comprises a plurality of basic patterns, wherein each of the plurality of basic patterns is within a rectangular region and comprises:
• a metal frame having a diamond shape;
• and
• two metal segments crossing with each other, each through a center of the diamond shape, and through two midpoints of two opposing sides of the diamond shape;
• wherein:
• four corner points of the diamond shape are respectively at four midpoints of four sides of the rectangular region;
• and
• the two metal segments are respectively two cross lines of the rectangular region.
