Abstract:
1. A display sheet comprising: a) an optional substrate for carrying layers of material; b) an imaging layer comprising a substantial monolayer of isolated domains of liquid-crystal material dispersed in a continuous matrix, said liquid-crystal material having a first reflecting state within the visible light spectrum defining an operating spectrum and a second weakly scattering state in said operating spectrum, wherein said states are capable of being interchanged by an electric field, which states are capable of being maintained as a stable state in an absence of an electric field, wherein said domains of liquid-crystal material comprises a mixture, coated as an emulsion to form the imaging layer, of at least two populations, a first population comprising a first liquid-crystal material having a first λ c) first transparent conductors disposed on one side of said imaging layer; d) second conductors disposed on an opposite side of said imaging layer.
