What is Smart Film ?
Privacy made simple. With a simple ON-OFF switch, PDLC film instantly transforms any glass from clear to opaque. This electrically switchable adhesive film can be applied to existing windows and glass, acting like an electronic blind when opaque, blocking visibility and enhancing security for any space.

How it works
The science behind instant privacy.
Smart Film Original (PDLC) puts microscopic liquid crystals inside a polymer layer, between two transparent conductive coatings. This thin construction gives existing glass the ability to switch between a clear view and a private, frosted appearance.
Electricity changes how the crystals are arranged. With power on, they align to let visible light pass through. With power off, they scatter light in different directions, obscuring the view while still bringing natural daylight into the room.

Small crystals. A visible difference.
PDLC stands for Polymer Dispersed Liquid Crystal. Its active layer responds to an electric field, changing the way light travels through the film rather than moving a blind or curtain.

Aligned for a clear view.
The liquid crystals line up, allowing light to pass through for a transparent viewing state.

Scattered for privacy.
The crystals return to a random arrangement, diffusing incoming light for a bright, frosted privacy state. Daylight remains; the direct view does not.

Smart Film Questions
Can Smart Film be applied to glass I already have?
Yes. Smart Film is a self-adhesive PDLC film applied directly to existing interior or exterior glass, windows and doors, so the glass does not have to be replaced.
What happens when the power goes off?
Film Original turns private when the power is off and still lets about 73% of daylight into the room. Film Reverse does the opposite and stays clear when unpowered.
How fast does it switch?
Under 45 milliseconds from private to clear and under 10 milliseconds from clear to private, so the change looks instant.
Does privacy mode block the view completely?
In privacy mode haze reaches 95%, so people and shapes cannot be made out while natural light still comes through. It is a privacy product, not a blackout blind.
Can I install it myself?
We do not recommend it. Our certified installers inspect the project, take precise measurements and apply the film, and a certified electrician makes the power connection. Busbar positions and wiring have to be planned before manufacturing.
How do I clean it?
Switch the film off, wipe with a soft cloth and 99% isopropyl alcohol, and make sure no liquid is left sitting on the edges.
How is it controlled?
With a wall switch, a remote, a smartphone, or through Alexa and Google Home. Panels can be grouped and scheduled.
How long does it last and what is covered?
The film is rated for 2 million switching cycles and a life cycle over 15 years, and it comes with a 2-year limited warranty.
