  • Publication number: 20130021393
    Abstract: A static electronic display employs pixels having a plurality of subpixels that exhibit one of a minimum intensity and a maximum intensity of an intensity range of the image. The static electronic display includes an array of the pixels of an electrode patterned to represent image pixels of the image. A relative number of minimum intensity subpixels and maximum intensity subpixels of each pixel in the array corresponds to an intensity level of a corresponding image pixel of the image.

  • 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.

  • Publication number: 20100090943
    Abstract: An electrophoretic display apparatus includes an array of cells each comprising first and second electrodes and a plurality of electrophoretic particles disposed between the electrodes, wherein the particles are dispersed in a host fluid and are multistable in positions between the electrodes; and drive circuitry in electrical communication with each of the electrodes. The drive electronics are configured to transition addressed cells of the array from a first optical state to a second optical state with a plurality of successive write signals.
