Switchable films & glass: A smart home solution
A smart switchable film is a groundbreaking technology that gives you complete control over the transparency.
How it works: The magic of PDLC Film (Switchable Glass)
At the core of this smart switchable glass film, a layer of liquid crystal molecules dispersed within a polymer matrix lies between two layers of transparent conductive film.
When it’s off: when they hit the crystals, it bounces around, making the glass look opaque.
When it’s on, the tiny bit of electricity lines up all the crystals neatly. Now, light can pass straight through, and the glass is transparent.
