Here’s How Smart Film Works




Smart film consists of thin sheets of PDLC (polymer dispersed liquid crystal). PDLC is made up of many thousands of liquid crystal droplets, which are dispersed across the film in a polymer. Without an electrical charge, the liquid crystal droplets randomly orient themselves across the polymer. In a random orientation, the droplets act a lot like the surface of a lake on a windy day. When the wind hits the surface of the lake, the droplets of the lake randomly orient themselves in response to the wind…
… and this random orientation ruffles the surface of the water and makes the surface of the lake opaque, so you can’t see through it to the lake floor.

Similarly, when the liquid crystal droplets of the PDLC smart film are randomly oriented without an electrical charge, they turn the surface of the film opaque white, so you can’t see through it.

Each of the liquid crystal droplets can (and do) move around when exposed to electricity. Specifically, when exposed to electricity, the droplets rearrange themselves into regimented patterns along parallel axes…
…and in those regimented patterns, the rearranged droplets allow light to pass through them. In this pattern, the droplets are rearranged and stilled, much like how the surface of a calm lake becomes crystal clear, so you can see through it to the lake floor.
