How does PDLC smart glass work?

With no applied voltage, the liquid crystals are randomly oriented and scatter the light which enters. When an electrical signal is applied, the liquid crystals orient themselves parallel to each other, allowing light through.

What is smart glass/film?

Smart glass/film is a switchable light control glass that turns a transparent glass to opaque instantaneously and vice versa.

How does smart glass/film works?

Smart glass works via electrical signal through activation of switches, sensors etc. Liquid crystal molecules turn to allow light to pass through and glass becomes transparent. It is opaque when not activated.

Can smart glass be used in outdoor applications?

Yes, smart glass can be installed in outdoor areas as normal laminated glass.

Does PDLC smart glass conduct electricity?

No, the internal PDLC layer is plastic and does not conduct electricity, since it is electrically insulated. Rather, it behaves more like a capacitor, where the applied signal alternates between positive and negative voltages at the plates of the capacitor, causing an alternating electric field throughout the PDLC dielectric, which is what aligns the liquid crystals with the frequency of the signal (normally 50 Hz or 60 Hz).

Which sectors are using PDLC glass?

Transportation
Architectural (residential and commercial)
Interior design
Retail advertising
Healthcare (i.e. hospitals and clinics, since the PDLC smart glass can replace unhygienic curtains and blinds which often carry microbes and germs, and this also improves air quality)
Banking, thanks to the privacy afforded to ATMs and as internal partitions
Hospitality, especially bathrooms, since more natural light can penetrate interior spaces lacking windows to the outside world.

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.
