Manufacturing method for conducting films on two surfaces of transparent substrate of touch control circuit
Abstract:
A manufacturing method for conducting films on two opposite surfaces of a transparent substrate of a touch control circuit, includes: contacting a first photoresist layer having photosensitive and discolored emulsion on a first conducting coat formed on a first surface of the transparent substrate, and contacting a second photoresist layer on a second conducting coat formed on a second surface of the transparent substrate; exposing the first photoresist layer to form a circuit pattern with distinguishable color on exposed regions of the first photoresist layer; employing the circuit pattern as an aligning benchmark for the second photoresist layer, and exposing the second photoresist layer accordingly; developing and etching those arranged on the two surfaces of the transparent substrate at the same time to form a first conducting film of a touch control circuit from the first conducting coat and form a second conducting film of the touch control circuit from the second conducting coat. Thus the manufacturing steps of the touch control circuit are decreased.
