Patent ID: 7754295

Claim:
A display comprising at least one substrate, at least one electronically modulated imaging layer and at least one electrically conductive layer, wherein said electronically modulated imaging layer comprises a self-assembled, close-packed, ordered monolayer of domains of guest-host material, the domains are dispersed as micron sized droplets in an aqueous medium mixed with a suitable binder material, wherein said guest-host material comprises a dichroic or pleochroic dye guest in a light modulating host in a fixed polymer matrix, and wherein said display is independent of viewing angle and wherein said dichroic or pleochroic dye guest is at least one dye selected from the group consisting of 4,4′-bis(4-N,N-dimethylamino-2,6-dimethylphenylazo)azobenzene, 4,4′-bis-(4-N,N-dimethylamino-2-phenylazo)azobenzene, 4,4′-bis-(4-N,N-diethylamino-2-methylphenylazo)azobenzene, 4,4′-bis-[2,5-dimethyl-4-(4-ethybminonaplithylazo)-phenylazo azobenzene and 4,4′-bis-[2,5-dimethy-4-(4-methylaminonaphthylazo)phenylazo]lazobenzene.
