Abstract
Semi-retro-reflective, semi-specular, specular and etched glass displays are equipped with a dielectric layer. This leads to displays with enhanced brightness, improved electrophoretic particle responsiveness, improved grayscale and chemical stability in the presence of an electrophoretic medium, electric field and high temperatures. In one embodiment, a reflective image display comprises a front sheet further comprising a plurality of hemispherical protrusions, front and rear electrodes, a dielectric layer on the surface of at least one electrode, liquid medium with electrophoretically mobile particles, color filter array layer and a directional front light system.
