smart film switchable

Most PDLC films block over 99% of harmful UV-A and UV-B rays, protecting furniture, fabrics, artwork, and skin from fading and damage. It eliminates the need for curtains, blinds, or Venetian blinds, offering clean lines, expansive views when desired, and maximizing the perception of space. It contributes to a contemporary, high-tech aesthetic. This thin, transparent laminate is based on a central functional layer composed of microscopic liquid crystal droplets dispersed in a polymer matrix. This layer is sandwiched between two transparent conductive films (typically ITO, Indium Tin Oxide) and two outer, durable PET (Polyethylene Terephthalate) backing layers.

The operating principle is elegant in its simplicity and relies on the response of liquid crystals to an electric field. When the film is not powered (OFF state), the liquid crystal molecules within the droplets are disordered. In this chaotic configuration, light passing through the film undergoes intense scattering, making the glass translucent, opaque, or frosted. This state ensures immediate privacy and effective reduction of solar glare. Applying a low AC voltage (commonly 48V AC or 65V AC) across the conductive layers (ON state) generates an electric field.

This field forces the liquid crystal molecules to align along its direction. With the molecules aligned, light passes through the droplets with minimal scattering, making the glass perfectly transparent and offering a clear view of the surrounding environment. The transition between the opaque and transparent states is extremely rapid, typically occurring in less than a second, and is completely reversible. The advantages offered by PDLC technology are numerous and significant. The most obvious is instant and reversible privacy control: with a simple command (switch, remote control, mobile app, or integrated home automation system), you can switch from full transparency to complete privacy.
