ELECTROSTATIC GENERATING DISPLAY PARTICLE AND MANUFACTURE

摘要

A process for producing particles for use in electrophoretic displays, wherein a heavy, solid pigment preferred for its high contrast or refractive index properties is coated with a polymer starting material. The process significantly reduces the specific density of the resultant particle, and creates particles with smooth polymer surfaces that can be chosen for stability in a given electrophoretic carrier fluid, and possess acceptable electrophoretic characteristics.
