Abstract: An automotive glazing panel has an electrically heatable solar control coating layer, spaced first and second bus bars positioned respectively adjacent a first and a second side edge of the glazing panel and adapted to relay electrical power to the coating layer and a data transmission window positioned adjacent the top edge of the glazing. This arrangement may be used to alleviate or reduce perturbations to heating of the glazing panel caused by the presence of the data transmission window.

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.
