Abstract
Some embodiments are directed to a light modulator comprising transparent substrates, or a transparent substrate and a reflective or partially reflective substrate, multiple electrodes being applied to the substrates in a pattern across the substrate. A controller may apply an electric potential to the electrodes to obtain an electro-magnetic field between the electrodes providing electrophoretic movement of the particles towards or from an electrode.
