Switchable Film

The technology Polymer Dispersed Liquid Crystal (PDLC) film which is widely known as switchable film/smart film is based on LCD crystals sandwiched between layers of PET film. When a current is applied to the film the scattered crystals in different directions are aligned in the same direction and thus allow light to pass through, but when switched off the crystals are scattered & misaligned with each other thus preventing the light to pass through and thus the film becomes opaque.
