Characteristics of Switchable Film (PDLC FILM, Magic Film, Smart Film)

pincible of the privacy glass

+ The translucent state of switchable film

The switchable film is composed by two transparent conductive film laminating with a polymer liquid core. And the polymer liquid core composes crystal ball and polymer. When the light pass through the PDLC FILM and reach the liquid crystal ball and polymer, the light is scattering. And the switchable film appears translucent.

+ The transparent state of switchable film

When electricity power is connected, the polymer-liquid crystal core is allowing light pass through, the switchable film appear transparent.

+ Haze of switchable film

To identify the switchable film quality, haze (the opposite is transparence ) is the key parameter to describe the switchable film. When the power is on, the switchable film should be as transparent as possible , when the power is off, the switchable film should be more haze.

+ View range of the switchable film

If the scattering is more, the view range is wide, the switchable film appears more haze.
