Are the only states of PDLC just ON and OFF?-Global Smart Glass

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.

FAQ >>>

What is the power source of smart glass/film?

Smart glass/film is operated using 48-65VAC power supply. Transformer will be needed for 110-230V power source.

FAQ >>>

Can smart glass/film be regulated to gradually change its state?

Yes, smart glass/film can be regulated to slowly transform from opaque to transparent or vice versa. A transformer with dimmer function is needed.

FAQ >>>

What is smart glass comprised?

Smart glass is a laminated glass comprising 2pcs of glass sandwiched in between by an EVA/PVB interlayer.

FAQ >>>

Can smart glass/film be used in wet areas?

Yes, smart glass/film can be used in wet areas such as bathrooms. The edges of smart glass/film are are sealed with a non-acid silicone gel that prevent any contact with water.

Are the only states of PDLC just ON and OFF?

No, the transmittance (level of transparency) of the PDLC can be varied from 0% in the OFF state up to any value you want until you reach the maximum transmittance (normally 70% or 80%). This is done by simply altering the voltage from 0 VAC up to 70VAC, which is typically the maximum recommended voltage. This can be done electrically with a variable isolating transformer, or electronically with a switched-mode smart glass dimmer.
