Realizing bright and vivid full colour performance in electrophoretic displays presents a significant challenge to display architects and material designers. A range of dyed polymeric microparticles with tunable size, charge and colour have been developed. When formulated as colloidal dispersions in low dielectric constant media, the particles are electrophoretically active and are suitable for use in full colour or monochrome electrophoretic displays.
