ABSTRACT:
A transmissive electro-optic display includes a substantially transparent front plane and back plane element. The back plane element includes a plurality of electrodes distributed in two dimensions on the backplane, each allowing independent control of a discrete region of the display. The front plane element includes at least one electrode disposed opposite the back plane, and is spaced apart from the back plane element by an interior wall defining a plurality of cells therebetween. A plurality of partially conductive and optically anisotropic elements is rotatably disposed in the plurality of cells, together with a dielectric fluid. When an appropriate electric field and/or a magnetic field is applied to the cells, the corresponding anisotropic elements are caused rotate between a “transmissive” state and an “opaque” state.
