PDLC film (Polymer Dispersed Liquid Crystal film) is a light modulating material comprised of droplets of liquid crystal uniformly dispersed in a transparency or translucency, flexible plastic film. When power off, coming visible light scatters through the PDLC, and the film turns translucent; When power on, coming visible light transmits the PDLC and the Film turns clear. The PDLC film would be applied on glass by special processing, so that have innovatory products called as PDLC (Polymer Dispersed Liquid Crystal) Glass is a kindly laminated glass, which can change to be transparent or non-transparent in instant by switching the electricity power by means applying with PDLC film.
