We supply massive rolls intelligent film and custom size ones with bus-bars to the glass processed factories which are looking to produce your own switchable smart glass.
Why is PDLC considered to be smart?
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.
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).
Can smart glass be used in outdoor applications?
Yes, smart glass can be installed in outdoor areas as normal laminated glass.
How much light does PDLC glass transmit?
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.
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.
