  • Patent number: 8089687
    Abstract: Electro-optical display systems are disclosed. An electro-optical display system may include a display volume containing a fluid having a plurality of colorant particles; a dielectric layer adjacent the display volume, the dielectric layer including recessed regions configured to contain the plurality of colorant particles; a plurality of electrodes configured to selectively move the plurality of colorant particles between a compacted position in which all or nearly all of the plurality of colorant particles are in the recessed regions, and a spread position in which all or nearly all of the plurality of colorant particles are spread across the display volume; and at least one color filter configured to absorb at least one wavelength of light.
    Type: Grant
