Abstract

A transparent pane having an electrically heatable coating and at least one coating-free zone that can be used, for example, as a communication window, is disclosed. 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 subdivision of one of the two collecting electrodes into separated subregions, each connected, via an electrical supply line, to an additional electrode. In one case, the electrical supply line runs, at least in sections, 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 disclosed.
