Smart glass/film is a switchable light control glass that turns a transparent glass to opaque instantaneously and vice versa.
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.
Switchable Toughened Glass
Switchable Laminated Glass
Switchable Double-Glazing
Switchable Window Film
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.
Yes, smart glass/film is a safety glass. Being laminated, it prevents scattering of glass fragments in case of breakage.
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.
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.
