Film for a light valve, and method for manufacturing the film. |
摘要 |
<p>A film (13) for a light valve is made by phase separation of a mixture comprising a homogeneous polymeric solution and a liquid suspension of light-polarizing particles. Uniform liquid-suspension droplets in a polymeric matrix are formed by phase separation processing. e.g., by polymerization or solvent evaporation. Such simple, one-step processing results in cost reduction in display and window applications. Sealing problems of conventional light valves are alleviated. <IMAGE></p> |
