Electrical functional layer construction, production method and use thereof

摘要

Transparent electrically conductive functional layer, production process and use thereof.;The invention concerns a transparent electrically conductive functional layer, in particular a laminate body. The invention makes it possible for the first time to produce thin conductive functional layers for use in resistive touch screens, for example in a printing process. By way of example with a coverage of 5% and adequate conductivity the functional layer still works at 95% transparent for the human eye.

主权项

1. An electrical functional layer construction comprising:
a flexible film transparent carrier; and a plurality of spaced conductive, non-transparent tracks on the carrier exhibiting no parallel straight lines and segmented into individual electrically connectable electrical conductive segments, the tracks having a thickness in the range of 2 nm to 5 μm, and being parallel to the surface of the transparent carrier, forming a pattern; the pattern having a conductor track spacing which ensures areal conductivity on the film carrier with at the same time transparency to the human eye, wherein the conductive tracks have at least one intersection point.
