Transparent Conductive Film Provides Electromagnetic-Wave Shield
Panasonic Industry recently released FineX (“FineCross”), a next-generation transparent conductive film engineered for high-performance electromagnetic-wave shielding. Suitable for advanced or sensitive display, industrial, and wireless communication environments, FineX provides high optical transmissivity, ultra-low electrical resistance, and excellent design flexibility.
Based on Panasonic’s proprietary ultra-fine copper metal-mesh microfabrication technology, FineX has precise, uniform wiring structures that achieve both low resistance and high visibility. The film is supplied in roll format with pre-applied optical clear adhesive (OCA), enabling smooth, bubble-free lamination and easy handling.
A high wiring aspect ratio ensures extremely low electrical resistance. The film thus supports fast, uniform heating and stable current flow, ideal for devices needing responsive thermal characteristics or high conductivity without compromising transparency.
In addition, the design flexibility of its copper mesh patterning enables the creation of complex mesh patterns tailored to various design requirements for electromagnetic-wave shielding and the achievement of a diffractionless product.
Thin-film-based materials and ultra-fine wiring enable a high level of flexibility and bending for installation on curved, shaped, or other non-flat surfaces. FineX arrives ready for lamination with a clean and consistent OCA layer, reducing process steps, minimizing contamination risks, and improving overall productivity.
