摘要： An optical switch for controllably switching an interface (12) between a reflective state in which incident light (14A) undergoes total internal reflection and a non-reflective state in which total internal reflection is prevented. In one such switch an elastomeric dielectric (10) has a stiffened surface portion (18). An applied voltage moves the stiffened surface portion into optical contact with the interface, producing the non-reflective state. In the absence of a voltage the separator moves the stiffened surface portion away from optical contact with the interface, producing the reflective state. In another such switch a cell (40) contains a fluid (42). One side of the cell forms the light incident interface (54). A membrane (44) is suspended in the fluid. Application of appropriate voltages can move the membrane either into optical contact with the interface, producing the non-reflective state, or away from optical contact with the interface, producing the reflective state.

摘要： Charged particles (21) suspended in a medium (20) such as Fluorinert 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 (35, 32, 81) 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 (36) front lights the display with sequential flashes of red, blue and green light to generate a full colour display. TIR can also be controlled at retro-reflective surfaces by means of a vapour-liquid phase transition, or by changing the absorption coefficient of a material using electrical, chemical and/or electrochemical methods.
