Reverse Switchable Privacy
PriWatt PNLC Film
PriWatt PNLC Film is an advanced reverse-mode switchable film engineered for spaces where transparency is needed most of the time.
Clear When OFF · Private When ON · Custom Fabricated in North America
ABOUT PRIWATT PNLC FILM
Clarity by Default. Privacy on Command.
Unlike conventional smart film, which is private when power is OFF, PriWatt PNLC Film operates in reverse.
When power is OFF, the liquid crystal structure remains highly transparent, providing unobstructed views and natural daylight. When power is applied, the film instantly transitions to its privacy state, reducing visibility through the glass.
This reverse operating mode makes PNLC ideal for applications where glass remains transparent most of the time and privacy is only needed occasionally.
OFF State (Default)
Clear with No Power
- Highly transparent appearance
- No continuous electrical power required
- Maximizes daylight and outdoor views
- Ideal for everyday operation
- No continuous power required in the clear state
ON State
Instant Privacy
- Glass switches to its private state in milliseconds
- Reduces visibility through the glass
- Maintains a clean, modern glass appearance
- Activated by wall switch, remote, app, or automation system
- Returns to clear instantly when power is removed

How It Works
How PNLC Reverse-Mode Film Works
PriWatt PNLC (Polymer Network Liquid Crystal) Self-Adhesive Film utilizes an advanced liquid crystal network positioned between transparent conductive ITO layers. Unlike conventional PDLC technology, PNLC is engineered with a reverse operating mode, allowing the film to remain highly transparent when no electrical power is applied.
When voltage is supplied, the liquid crystal network changes its optical alignment, transforming the glass into a private state that reduces visibility while maintaining a clean, modern architectural appearance. This unique switching sequence makes PNLC ideal for applications where glass remains transparent throughout most of the day and privacy is only required occasionally.
Inside PNLC Technology
PriWatt PNLC Film combines advanced Polymer Network Liquid Crystal technology with transparent conductive ITO coatings to create reliable reverse-mode switchable privacy.
Unlike conventional PDLC systems that become transparent when energized, PNLC operates in reverse.

Frequently Asked Questions
PriWatt PNLC (Polymer Network Liquid Crystal) Self-Adhesive Film is an advanced reverse-mode switchable privacy film that transforms existing glass into switchable privacy glass. Unlike conventional PDLC technology, PNLC remains highly transparent when power is OFF and switches to privacy only when electricity is applied.
The primary difference is the operating mode. PDLC (Normal Mode) Power OFF = Private Power ON = Transparent PNLC (Reverse Mode) Power OFF = Transparent Power ON = Private PNLC is ideal for applications where glass remains transparent most of the day and privacy is only required occasionally.
