1. An ultra-thin composite transparent conductive film, comprising:
a transparent substrate;
a first UV glue layer disposed on one side of the transparent substrate, pattern-imprinted and cured to form a first grid-shaped groove, the first grid-shaped groove being filled with conductive materials to form a first conductive layer;
a second UV glue layer disposed on one side of the first UV glue layer away from the transparent substrate and used as a reinforced insulating support layer; and
a third UV glue layer disposed on one side of the second UV glue layer away from the transparent substrate, pattern-imprinted and cured to form a second grid-shaped groove, the second grid-shaped groove being filled with conductive materials to form a second conductive layer,
wherein a friction coefficient of cured surfaces of the first UV glue layer and the third UV glue layer is lower than a friction coefficient of cured surfaces of the second UV glue layer, and
wherein a thickness of the reinforced insulating support layer is in a range of 5-10 micrometers.
