Liquid Crystal Gels for Display Applications

摘要

The reversed and normal mode anisotropic liquid crystal gels with low operating voltage, high contrast ratio, broad bandwidth, wide viewing angle, and fast response time were demonstrated. By incorporating a /4 film between the gel and a reflector, this reflective device is useful for modulating unpolarized light. Potential applications of such an anisotropic gel as a broadband switchable polarizer, reflective display, and transflective display are emphasized.
