SMART FILM
Smart Film, also known as Switchable Smart Film, PDLC Film, or Electronic Privacy Film, is an advanced window film that allows glass to change from transparent to opaque (frosted) with the flip of a switch, remote control, or smartphone app.
It is becoming increasingly popular in the architectural, commercial, and residential window film industries because it provides instant privacy while maintaining a modern appearance.
Smart Film uses a technology called Polymer Dispersed Liquid Crystal (PDLC).
It consists of several layers:
-
Protective PET film layers.
-
Transparent conductive coatings.
-
Liquid crystal material.
-
Polymer matrix.
-
Electrical connections that supply power.
When electricity is applied:
-
Liquid crystals align.
-
Light passes through the film.
-
The glass becomes transparent.
When electricity is turned off:
-
Liquid crystals become randomly oriented.
-
Light scatters through the film.
-
The glass becomes opaque or frosted.
This transition happens almost instantly.
