Color variance polymer matrix display having two scattering states or N.sub . <or> both N.sub.E and N.sub.O

A color variance polymer matrix display comprising:

• a polymer matrix;
• droplets of liquid crystal material dispersed in said polymer matrix to produce two fully scattering states, said liquid crystals having optic axes uniformly aligned in one direction upon application of an electric field of sufficient magnitude to said polymer matrix;
• a mixture of dyes incorporated in said liquid crystal droplets such that the polymer matrix exhibits color changes ranging between a first color and a second color in response to changes in the magnitude of the electric field matrix;
• whereby said display will produce said first color in the absence of an electric field to said polymer matrix and said second color when an electric field of sufficient magnitude is applied to said polymer matrix;
• and
• whereby said display will produce shades of color between said first and second colors upon application of an electric field having a magnitude above zero and less than said sufficient magnitude to said polymer matrix.

A color modulating device changes from a first color to a true colorless state, said device comprising:

• a transparent superstrate;
• a substrate spaced from said superstrate,
• a polymer matrix interposed between and in contract with said superstrate and substrate;
• droplets of liquid crystal material dispersed in said polymer matrix, said liquid crystal material having optic axes uniformly aligned in one direction upon application of an electric field across said polymer matrix;
• a mixture of dyes incorporated in said liquid crystal droplets such that the polymer matrix exhibits color changes ranging between a first color and a true colorless state in response to changes in magnitude of said electric field;
• wherein each index of refraction of said liquid crystal droplets is greater or less than the index of refraction of said polymer matrix;
• whereby said display will produce said first color in the absence of an electric field across said polymer matrix and will attain a true colorless state when an electric field of sufficient magnitude is applied across said polymer matrix;
• and
• whereby said display will produce said color in reduced levels of intensity upon application of an electric field having a magnitude above zero and less than the said sufficient magnitude across said polymer matrix.
