Transparent Glass Window Privacy Film , Energy Saving Switchable
Privacy Glass
Glass Window Privacy Film Description
Glass Window Privacy Film is a product that is capable of adjusting
light transmission between transparent and opaque using AC power.
Due to moisture sensitivity, earlier versions of the film were used
only to make smart glass by lamination on glass. With continual
improvement in moisture resistance, the new (3rd) generation of the
film can be directly installed on existing windows with special
glue or self-adhesive. It combines many functions, such as light
adjustment, UV and infrared blocking, advertising and security.

In polymer-dispersed liquid-crystal devices (PDLCs), liquid
crystals are dissolved or dispersed into a liquid polymer followed
by solidification or curing of the polymer.
During the change of the polymer from a liquid to solid, the liquid
crystals become incompatible with the solid polymer and form
droplets throughout the solid polymer.
The curing conditions affect the size of the droplets that in turn
affect the final operating properties of the "smart window".
Typically, the liquid mix of polymer and liquid crystals is placed
between two layers of glass or plastic that include a thin layer of
a transparent, conductive material followed by curing of the
polymer, thereby forming the basic sandwich structure of the smart
window. This structure is in effect a capacitor.
How does switchable privacy glass work?
Through the application of an electrical current the properties of
the glass change turning it from opaque to clear in less than 0.01
seconds. This transformation to opaque and back again can be
triggered from a range of wall switches, remote controls, movement
sensors, light sensors or timers, depending on each customer’s
individual needs. Numerous variations of privacy switchable glass
can be supplied including colour tinted, fire rated, double glazed,
curved and shaped privacy glass.
The original ON/OFF switchable smart glass is a laminated glass
panel with a polymer dispersed liquid crystal interlayer film
(PDLC). It offers instant privacy at the flick of a switch by
changing its state from transparent to opaque and vice versa
through a small electrical current.
Once activated, Electric Glass turns transparent for as long as the
transformer is running. When the electrical current stops, the
electric smart glass instantly returns to an opaque state.
