"based on light-controlled azimuth angle process using cholesteric liquid crystal optical rotatory effect to create single-layer, multi-microdomain, orthogonally twisted structures with low polarization dependence and high phase retardation... patterned light control enables precise alignment... have large phase depth... more efficient and reliable optical communications systems, wearable devices with clear and concise information display"
