Abstract:
A hybrid reflective-emissive display including an electrophoretic medium. The electrophoretic medium includes two types of oppositely-charged, and differently-colored, particles in a fluid. The electrophoretic medium is disposed between a front light-transmissive electrode and a rear electrode including a plurality of apertures, such as a hexagonal grid. The electrophoretic layer is optionally illuminated by a light source disposed on the opposite side of the rear electrode from the electrophoretic medium. A viewer can see either the first or second type of particle at the viewing surface, or one of the particles can be illuminated by the light source, thus emitting light the color of one of the particles.
