Display having viewable and conductive images
First Claim
1. A display for presenting selected images to a viewer, comprising:
- (a) a transparent substrate;
(b) a transparent, electrically conductive coating formed over the transparent substrate;
(c) a light modulating layer formed over the transparent, electrically conductive layer;
(d) a photosensitive layer formed over the light modulating layer which is adapted to be exposed and developed to provide viewable and conductive images;
(e) the light modulating layer being effective in two conditions, in a first condition to prevent the viewing of the viewable and conductive images and in a second condition to permit the viewing of the viewable and conductive images; and
(f) electrical conduction means connected to the viewable and conductive images and the transparent, electrically conductive coating for applying a field to selected ones of such viewable and conductive images to cause the light modulating layer to change from the first condition to the second condition so as to present such viewable and conductive images for viewing to the viewer.

Abstract
A display for presenting selected images to a viewer is disclosed, including a transparent substrate, a transparent, electrically conductive coating formed over the transparent substrate, a light modulating layer formed over the transparent, electrically conductive layer and a photosensitive layer formed over the light modulating layer which is adapted to be exposed and developed to provide viewable and conductive images. The display further includes the light modulated layer being effective in two conditions, in a first condition to prevent the viewing of the viewable and conductive images and in a second condition to permit the viewing of the viewable and conductive images, and an electrical conduction structure connected to the viewable and conductive images and the transparent, electrically conductive coating for applying a field to the selected ones of such viewable and conductive images to cause the light modulating layer to change from the first condition to the second condition so as to present such viewable and conductive images to the viewer.

13. 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 coating over the transparent substrate;
(c) forming a light modulating layer including liquid crystal material in a gelatin over the transparent, electrically conductive layer to be effective in a first condition to prevent the viewing of viewable and conductive images and in a second condition to permit the viewing of viewable and conductive images;
(d) forming a photosensitive layer including silver halide over the light modulating layer and exposing and developing such photosensitive layer to provide the viewable and conductive images; and
(e) providing electrical connection so that an electrical field can be applied across selected ones of such viewable and conductive images and the transparent, electrically conductive layer to cause the light modulating layer to change from the first condition to the second condition so as to present such viewable and conductive images for viewing to the viewer. - View Dependent Claims (14, 15, 16)
