Abstract

A transparent pane having an electrically heatable coating and at least one coating-free zone that can be used, for example, as communication window, is presented. The electrically heatable coating is connected to two collecting electrodes, such that a supply voltage applied to the electrodes generates a heating current that flows via a heating field formed between the collecting electrodes, the heating field containing the coating-free zone whose zone-edge is formed, at least in sections, by the heatable coating. Other implementation details include provision of two electrical supply lines electrically connecting the two collecting electrodes to separate subdivisions of an additional electrode. In one case, the electrical supply lines run, at least in sections, in the heating field, in the coating-free zone, in a coating-free edge strip, in a subregion of the coating outside the heating field, and/or in the zone-edge. Methods for producing the transparent pane are also presented.
