PDLC SMART FILM

PDLC Smart Film is a Polymer Dispersed Liquid Crystal Film encapsulated between two layers of conductive inter layers that are Plastic substrates (PET) applied with conductive layers (ITO). Through the applied power control, the (PDLC) films can quickly 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 the 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, this changes the Smart Film from opaque to clear.

Working principle

Smart film ( switchable smart film / Opaque smart film) is mainly composed of two layers of ITO conductive film and an intermediate liquid crystal. Liquid crystal mainly consist of liquid crystal droplets and outer polymer.

When the power is off, the inner liquid crystal droplets are arranged in disorder. When the parallel light passes through the polymer and illuminates the liquid crystal material, the refractive index of the liquid crystal droplets is lower than that of other outer polymers.

When electrified, the two ITO conductive films act as planar electrodes, so that the light can pass through the whole smart film, and the smart film is transparent.

Smart film could be classified as self-adhesive film, and non-adhesive film.

Application

Smart film has be used in various scenarios as privacy protection film, such as conference room, villa, hotel / bathroom, home/office partition, hospital, pharmacy, bank, consultation room, VIP room, shop, fitting room, wherever there's a glass.
