Abstract
An electro-optic display includes a “matrix” for confining moving elements of the display (e.g., rotating or twisting elements). The matrix (or at least the viewable portions thereof) may have a high reflectivity, comparable to that of white paper. This results in an overall “whiter” or brighter display. The matrix may include channels to facilitate inter-cell fluid transport and high-density element packing. In some cases, the matrix elements provide a hexagonal arrangement of cells for holding the rotating elements. The rotating elements of the display may be electrically and optically anisotropic hemispherically coated spheres. The hemispherical coating typically provides the necessary charge to create electrical anisotropy.
