摘要
Charged particles suspended in a medium such as Fluorinert(TM) Electronic Liquid are used to electrophoretically control total internal reflection (TIR) at a retro-reflective surface formed on a high refractive index material. Prismatic structures redirect ambient light from an overhead light source toward a display image and then from the image to the region in front of the image, yielding a high contrast reflective display. A transparent planar waveguide front lights the display with sequential flashes of red, blue and green light to generate a full color display. TIR can also be controlled at retro-reflective surfaces by means of a vapor-liquid phase transition, or by changing the absorption coefficient of a material using electrical, chemical and/or electrochemical methods.
