Abstract:
A method of forming a display in which images can be selectively presented to a viewer, comprising the steps of:a) providing a transparent substrate;b) forming a transparent, electrically conductive layer over the transparent substrate;c) forming a light modulating layer including liquid crystal material in a polymer binder over the transparent, electrically conductive layer;d) forming conductive colored segments over the light modulating layer by directly depositing colored conductive material in an imagewise pattern, the pattern providing viewable and conductive images;e) forming a colored dielectric layer over the conductive colored segments and the light modulating layer, the color of the dielectric layer being selected in relation to the color of the viewable color conductive segments so that when the light modulating layer is effective in a first condition, the viewing of the viewable color conductive segment images is prevented and in a second condition permits the viewing of the viewable color conductive segment images; andf) providing electrical connections so that an electrical field can be applied across selected ones of such viewable and conductive segments and the transparent, electrically conductive layer to cause the light modulating layer underlying the selected ones of the viewable and conductive images to change from the first condition to the second condition so as to present such color conductive segment images for viewing by the viewer.
