Transparent conductive film - FineX (Fine Cross)

The industry's first*1 “unique roll-to-roll construction method” used in double-sided full wiring metal mesh. (*1: Panasonic data as of February 16, 2022)

Panasonic’s Transparent Conductive Film FineX (Fine Cross) is …

The metal mesh type transparent conductive film, which achieves both high transmissivity and low resistance, was developed using Panasonic's proprietary method.

Since it can conduct electricity in transparent areas where visible light transmission is required, the following can be achieved:

Generation of capacitance
Current flow to the device
Generation of heat
