What is the warranty period for smart glass/film?

Warranty period is 2 years from date of installation. The life time of the film/glass is up to 10 years depends on varies working environment.

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).

>>>

Does PDLC smart glass become opaque?

No, the correct term is translucent, since light still gets through, albeit scattered in many directions. The glass would be opaque only if the light was blocked or absorbed.

>>>

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.

>>>

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.

>>>

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.
