APPARATUS AND METHOD FOR REFLECTIVE IMAGE DISPLAY WITH DIELECTRIC LAYER

摘要

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.

1. A reflective image display device, comprising:
a transparent front sheet comprising of convex protrusions or embedded spherical beads through which a viewer views the display; a front electrode; a rear support; a rear electrode; a dielectric layer located on the surface of at least one electrode; an optically transparent fluid medium a plurality of electrophoretically mobile particles suspended in the optically transparent fluid medium; and a voltage source for applying a bias across the optically transparent fluid medium to move the electrophoretically mobile particles.
