It is recognized that reflective displays will play an increasingly important role in future information devices, principally due to their readability under high ambient light conditions and their lower power consumption. Monochrome electrophoretic displays (EPD) already satisfy some aspects of this requirement. However, to extend this to bright and vivid colour will require developments beyond the use of a colour filter array over a black and white electrophoretic electro-optical layer. Saturated colour particles, optionally in combination with highly reflective white particles are required for creating fluids to realize colour-filter-free, full colour electrophoretic displays. The use of improved, dyed polymeric microparticles with tuneable size, charge and colour, together with white reflective composite particles as a full colour EPD media is demonstrated.
