Abstract
Disclosed is 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 and a first lead groove, the first grid-shaped groove and the first lead groove being filled with conductive materials to form a first conductive layer and a first lead region respectively, depth of the first grid-shaped groove and the first lead groove being smaller than a thickness of the first UV glue 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 and a second lead groove, the second grid-shaped groove and the second lead groove being filled with conductive materials to form a second conductive layer and a second lead region respectively, and depth of the second grid-shaped groove and the second lead groove being not greater than a thickness of the third U…
