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.

Glass Window Privacy Film Description:

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.
