Coated disk having a heatable communication window

摘要

A transparent disk that can be electrically heated over a large surface area, comprising: a large-surface-area, electrically conductive, transparent coating, which is applied to a transparent substrate, at least two bus ribbons, which are electrically connected to the electrically conductive transparent coating, at least one locally delimited region free from the coating, wherein at least one heating conductor having two poles is applied inside the free region, and wherein the first pole is electrically connected to the electrically conductive, transparent coating and the second pole is electrically connected to the electrically conductive, transparent coating or a bus ribbon. A method for the production of the disk is also described.

1. A transparent pane electrically heatable over a large area, comprising:
an electrically conductive transparent coating having a large surface, the electrically conductive transparent coating being applied on a transparent substrate; at least two current collector strips electrically connected to the electrically conductive transparent coating; at least one locally delimited region free of the electrically conductive transparent coating, each of the at least one locally delimited region being located between two current collector strips; and at least one heating conductor having a first pole and a second pole applied within the at least one locally delimited free region, wherein the first pole is electrically connected to the electrically conductive transparent coating and the second pole is electrically connected to either the electrically conductive transparent coating or to one of the at least two current collector strips.
