PDLC (Polymer Dispersed Liquid Crystal) 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 polymer and the liquid crystals are encapsulated in the PDLC. Both faces of the film are covered with a transparent ITO coating. Both ITO coatings are connected to a flat electrode, which is fixed on one of the edges of the film.
When the Film is switched off from its power supply, the liquid crystals are randomly scattered and diffuse light in all
directions. In this state PDLC is translucent and prevents both sides from seeing through the Film.By switching on, the crystals line up and re-orientate themselves, turning the Film totally transparent. Switching from on-transparent state to the transparent state is almost instantaneous and can be repeated as often as desired.
