Smart dimming film for decoration Functional Film
Description:
Smart dimming film for decoration 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.
It is also known as electronic dimming film, electronic curtain, smart film, PDLC film, dimmable film etc.
By switching on, the crystals line up and re-orientate themselves, turning the Film totally transparent.
Switching from non-transparent state to the transparent state is almost instantaneous and can be repeated as often as desired.
