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.
PDLC smart glass is composed of :
Outermost panels of normal float glass (or sometimes acrylic) sandwiched around:
Inner panels of optically clear PET plastic (polyethylene terephthalate), sandwiched around:
ITO (Indium Tin Oxide) which is a transparent conductor, sandwiched around:
a PDLC core comprised of liquid crystal droplets, suspended in a polymer.
Switchable Toughened Glass
Switchable Laminated Glass
Switchable Double-Glazing
Switchable Window Film
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.
Yes, smart glass/film is available in all irregular shapes as you want, including curved glass.
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.
