Title:
DOUBLE-SIDED CONDUCTIVE FILM, COATING METHOD, AND TOUCH SCREEN
Document Type and Number:
WIPO Patent Application WO/2022/007767
Kind Code:
A1
Abstract:
Embodiments of the present application disclose a double-sided conductive film, a coating method, and a touch screen. The conductive film comprises a transparent substrate, and a low-resistance conductive layer, a Cu layer and a protective layer sequentially stacked on each of two sides of the transparent substrate. The protective layer is a Cu alloy layer or a Mo alloy layer. The low-resistance conductive layer is used to conduct electricity, and the resistance of the low-resistance conductive layer is not greater than 100 ohms. In the technical solution of the present application, Cu is used to replace silver paste, and a Cu alloy is used to form the protective layer. As verified by testing, even if the line width × the line spacing is 5 µm × 5 µm after etching, electrical conductivity can still be guaranteed.
