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.
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.
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.
Smart glass is a laminated glass comprising 2pcs of glass sandwiched in between by an EVA/PVB interlayer.
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.
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.
Smart glass/film is a switchable light control glass that turns a transparent glass to opaque instantaneously and vice versa.
