Abstract

See full text

The display panel comprises surrounding media containing particles which are responsive to changes in a magnetic field are optically anisotropic toward the viewing surface. The electrode film has an array layer and an electrode layer, where the array layer provides a support structure for the electrode layer and electrically non conductive and in contact with the surface of the display panel and having. a plurality of mesa shaped segments where each mesa shaped segment has a top face and side walls extending downward from the top face. The electrode layer formed of an electrically conductive material coats the array layer and is exposed for contact by an electrical stimulus. The electrode layer is thicker on the top face than on the side walls, producing resistive bridges between adjacent top faces. The resistive bridges partially electrically isolate each electrode from the other electrodes in the electrode layer.
