Abstract
Electro-optical display systems are disclosed. An electro-optical display system may include a plurality of electrodes; a display volume containing a fluid having a plurality of colorant particles; a layer adjacent to or part of at least one electrode of the plurality of electrodes and configured to at least one of (i) reflect at least one wavelength of light and (ii) absorb at least one wavelength of light; and recessed regions configured to contain the plurality of colorant particles, wherein the plurality of electrodes are 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 the plurality of colorant particles are spread across the display volume.
