What is Smart Film Reverse ?
Privacy on demand, in reverse. PNLC reverse film stays clear when it is off and turns private the moment you switch it on. This electrically switchable adhesive film is applied to existing glass, so offices, meeting rooms and storefronts keep their view and daylight by default and get privacy only when they need it.

How it works
A clear view. Until you choose privacy.
Reverse PNLC technology keeps the viewing state clear without power. Apply power when privacy is needed, then switch it off to return to a transparent view.
Inside PNLC Technology
Smart Film Reverse (PNLC) combines Polymer Network Liquid Crystal technology with transparent conductive ITO coatings to create reverse-mode switchable privacy.
A clear view without power.
Unlike conventional PDLC film, PNLC remains transparent when the power is off.
Privacy when switched on.
Apply power to change to a frosted privacy state, then switch it off to restore the clear view.
An open, clear view.
A transparent viewing state connects the spaces.
Privacy when you need it.
A frosted appearance separates the space visually.

Smart Film Reverse Questions
What makes Film Reverse different?
Film Reverse (PNLC) is clear when the power is off and turns private only while it is switched on, the opposite of Film Original (PDLC).
What happens when the power goes off?
The glass stays clear, so the space keeps its view and daylight during a power outage.
Can it be applied to glass I already have?
Yes. Smart Film is a self-adhesive film applied directly to existing interior glass, windows and doors, so the glass does not have to be replaced.
How fast does it switch?
Under 5 milliseconds from clear to private and under 150 milliseconds back to clear, so the change looks instant.
Does privacy mode block the view completely?
In privacy mode haze reaches 94%, so people and shapes cannot be made out while natural light still comes through. It is a privacy product, not a blackout blind.
What colors are available?
Film Reverse is available in white only.
How is it controlled?
With a wall switch, a remote, a smartphone, or through Alexa and Google Home. Panels can be grouped and scheduled.
Can I install it myself?
We do not recommend it. Our certified installers measure and apply the film, and a certified electrician makes the power connection. Busbar positions and wiring have to be planned before manufacturing.
