Abstract
An automotive glazing panel having an electrically heatable solar control coating layer, spaced first and second bus bars adapted to relay electrical power to the coating layer and a data transmission window positioned at least partially in contact with the heatable solar control coating layer is arranged such that at least a portion of the periphery of the data transmission window is bounded by an electrically conductive band having an electrical resistance measured in ohms per square significantly less than the electrical resistance measured in ohms per square of the heatable solar control coating layer. This may be used to minimize perturbations to the heating of the glazing caused by the presence of the data transmission window and/or provide more even heating over the entire windscreen.
