Liquid crystals (LCs) and polymer-dispersed liquid crystals (PDLCs) are a relatively new class of materials that hold promise for many applications ranging from switchable windows to projection displays and are the focus of extensive research in the display industry. A joint University of Colorado-Kent State University research group has discovered a High Transmittance Stressed Liquid Crystal (HTSLC) in the visible spectra. The HTSLC embodies the benefits of stressed liquid crystal cells but are capable of near 100% transparency in the visible spectra. Advantages of the proposed invention over traditional PDLCs and liquid crystal cells include an easy and efficient fabrication process which makes large scale production possible, high transmittance in both the visible and infrared range, and an ultra-fast response time for both thin and thick cells. Applications include infrared beam steering, adaptive optics, compact telescopes, camera lenses, etc.
