PDLC film (polymer dispersed liquid crystal film also called switchable privacy glass pdlc film) which is a kind of high-tech product can switch from transparent to opaque instantaneously under electricity application. It is transparent when power on and it is opaque when power off. It can be regulated and adjusted the light transmittance pass through the film by electricity supply.

The film is composed of PET film,ITO film,polymer and liquid crystal molecules. When the film is under off state, the randomly aligned liquid crystal molecules stay along on the walls of capsule, the reflection of liquid crystal molecules and polymer makes light disperses then it is opaque. While electricity supplied, these molecules arrange themselves in a specific direction then parallel light can pass through the film makes it transparent.
