Is smart glass/film a safety glass?
Yes, smart glass/film is a safety glass. Being laminated, it prevents scattering of glass fragments in case of breakage.
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.

Smart glass/film is operated using 48-65VAC power supply. Transformer will be needed for 110-230V power source.
The smartness of PDLCs is a result of its ability to change its transparency (technically called the transmittance) when an electrical stimulus is applied to it. This is normally by way of an alternating voltage, which exerts an alternating electric field across the PDLC material.
Nevertheless, the PDLC is only as smart as the control system which stimulates the change, which can be driven by a push button switch, a light sensor, or a building automation system.
Yes, smart glass/film is a rear projector screen with wide viewing angles. Even from the side one can enjoy clear, beautiful images and also in bright locations with high functional projectors.
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.
Enhanced security (since the glass is shatter-proof thanks to the internal plastic lamination)
Privacy (thanks to the scattering of light, essentially hiding whatever is behind the smart glass)
Glare reduction (again thanks to the scattering effect)
Reduction of the carbon footprint of the building thanks to the solar control, which reduces HVAC needs, both in summer and in winter
Reduced colour fading of interior furnishings and artworks, thanks to the rejection of UV
Creative marketing, since when the PDLC smart glass is off, the scattering effect creates a screen upon which you can project images.
