A TWISTING BALL DISPLAY

摘要

A gyricon or rotating-particle display having an auxiliary optical structure may be provided as an auxiliary optics for a twisting ball display . A gyricon or rotating-particle display may have an "eggcrate" substrate. Further, a combination of an optically transmissive dielectric fluid having a first refractive index and an optically anisotropic particle rotatably disposed in the fluid may be provided.
