Abstract
Optically heterogeneous display elements utilize fused pigment particles, which may be manufactured with polymer shells having desired charge, photoresponse, or density characteristics. The particles may be microencapsulated prior to formation of the display element, so that the element is formed internally within the container in which it is permanently housed. The element may function as a bichromal display, a light valve, or a programmable magnetic element.
