Abstract:
A rotating element display includes a matrix having discrete regions of cells of different sizes occupied by rotatably disposed optically and electrically anisotropic elements (e.g., electrically anisotropic bichromal spheres). The regions of larger cells are occupied by larger rotating elements having a first combination of optical properties while the regions of smaller cells are occupied by smaller elements having a second combination of optical properties. The rotating elements having different combinations of optical properties are separately addressable by electromagnetic signals that cause rotation of selected optically dissimilar elements and create a desired color image. In a different aspect, a rotating element display includes a plurality of optically anisotropic rotatable elements occupying cells of a transparent matrix, in a configuration where a background color is viewable through the matrix. A color image is created using a combination of background color with optical properties of the rotating elements.
