Abstract
New reflective display architecture embodiments are disclosed to create specular or paper-like reflectance comprising a transparent outer sheet with an optional light diffusing layer, a rear backplane electrode, a perforated continuous reflective or non-reflective film with a thin conductive reflective or transparent layer acting as a front electrode facing the transparent outward sheet placed between the transparent outward sheet and rear backplane electrode. Other variations include semi-retroreflective or sintered TiOlayers atop the front electrode. Light is modulated by reflectance or absorbance of the light rays that pass through the transparent outward sheet by movement of light absorbing electrophoretically mobile particles within an optically transparent liquid or air medium. A voltage bias is applied across the medium by a voltage source to move the electrophoretically mobile particles.
