Abstract:
An electrode means comprising first and second thin-film electrode layers with electrodes in the form of parallel strip-like electrical conductors in each layer, wherein the electrodes of the second electrode layer are oriented crosswise or substantially orthogonally to the electrodes of the first layer, wherein at least one of the electrode layers is provided on an insulating surface of a substrate or backplane, and wherein the electrode layers are provided in parallel spaced-apart planes contacting a globally provided layer of a functional medium therebetween, wherein each of the thin-film electrode layers comprises:a first set of said strip-like electrodes of width wa and thickness ha, the electrodes of the first set being mutually spaced apart by distance d equal to or greater than wa; and a second set of said strip-like electrodes with width wb and thickness hb provided in the spacings between the electrodes of the first set and electrically insulated therefrom by a thin film of an electrically insulating material with thickness &dgr; and at least extending along the side edge of the parallel electrodes and forming an insulating wall of thickness &dgr; therebetween, the magnitude of &dgr; being small compared to the magnitude of either wa or wb, with the spacing distance d between the electrodes of the first set being wb+2&dgr;, and that the electrode layers with electrodes and the insulating thin film respectively form global planar layers in the electrode means.
