Abstract
A display system includes a switchable display screen comprising a first transparent substrate, a first transparent conductive layer disposed upon the first transparent substrate, a second transparent substrate, and a second transparent conductive layer disposed upon the second transparent substrate. The display screen further includes a polymer-stabilized cholesteric texture layer and spacer elements disposed between and in contact with the first transparent conductive layer and the second conductive layer. The display screen comprises a plurality of addressable regions, each region capable of being switched from a transparent state to a diffuse state.
