When not connected to a voltage, typically the transmittance can be as low as 2%. When connected to a voltage, it can be up to 80%, but this maximum value varies from manufacturer to manufacturer.

- FAQ
Can smart glass/film be used in bathroom?
Yes, smart glass and film can be used in moisture areas so long as the edges are sealed with a non-acid silicone gel. For bathrooms, we recommend using our smart glass product as the switchable PDLC layer is protected from water by the glass. All electrical components need to be sealed and protected from contact with moisture.

How much light does PDLC glass transmit?
What is the structure of PDLC glass?
PDLC smart glass is composed of :
Outermost panels of normal float glass (or sometimes acrylic) sandwiched around:
Inner panels of optically clear PET plastic (polyethylene terephthalate), sandwiched around:
ITO (Indium Tin Oxide) which is a transparent conductor, sandwiched around:
a PDLC core comprised of liquid crystal droplets, suspended in a polymer.
What is a Liquid Crystal?
A liquid crystal is a hybrid between (i) a liquid which flows like a fluid and (ii) a crystal which is normally found as a solid, exhibiting short- or long-range symmetry.
Why does PDLC require a polymer?
The polymer allows the liquid crystals to be embedded into a film, which can then be sandwiched between panels of glass or plastic. The polymer has constant optical properties which do not vary across its structure, and hence is considered isotropic.
In contrast, the liquid crystal itself is anisotropic, since its optical characteristics are not constant across its structure, but rather can vary under application of an electric field.
What is the power consumption of smart glass/film?
Smart glass/film consumes less than 5W/sqm.
