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 plastic film. When a current is applied to the film the crystals are aligned in the same direction and thus allow light to pass through but when switched off the crystals are misaligned with each other preventing light to pass through and thus the film becomes opaque.
The All New Polymer dispersed liquid crystal [PDLC] popularly known as Switchable Glass/Smart Glass can switch appearance with instant transitionfrom clear to opaque& vice versa, in milliseconds.
In its un-switched state or OFF state, the liquid crystals diffuse light, rendering the glass opaque. When switched ON, the liquid crystals align, allowing light to transmit without diffusion. Also, by variable voltage control, any state from clear to opaque can be programmed. It is definitely an improvement on curtains and blinds.
