Abstract
A method for manufacturing a transparent conductive film includes: using a mold to stamp on a transparent insulating substrate to obtain continuous grooves; or coating a gel layer on a transparent insulating film, then using a mold to stamp on one plane of the gel layer which is away from the transparent insulating film, so as to form solidified grooves; filling the grooves with conductive materials to generate a conductive layer, i.e., an inner circuit; forming an outer circuit on the surface in contact with the conductive layer; removing the unnecessary conductive materials in the inner and outer circuit in accordance with a preset graphic to form insulating channels, and insulating lines; obtaining a transparent conductive film. Screen printing and embedded nano-imprinting are combined, and a unified grid filling system is used as a general-purpose mold to manufacture a transparent conductive film.
