What Is Smart Film?
Smart Film is a Polymer Dispersed Liquid Crystal (PDLC) Film encapsulated between two layers of conductive inter layers that are Plastic substrates (PET) applied with conductive layers (ITO).
By applying the power control, the Polymer Dispersed Liquid Crystal film can swiftly change from clear (On) and opaque (Off).
When the power of Smart Film is turned Off, the liquid crystal turn into scattering position and the micro reflective index of material is mismatched, resulting in the strong scattering effect, that leaves the Smart Film opaque.
When power is turned On to the Smart Film, the liquid crystals lines up and the reflective index do the same. Then the scattering is sharply depressed, changing the Smart Film from opaque to clear.
