Product introduction
PDLC technology & working principle
PDLC smart film adopts polymer dispersed liquid crystal technology. It is a functional optical film formed by coating liquid crystal polymer between two layers of flexible ITO conductive films and then laminating them together. The arrangement of liquid crystal molecules can be controlled by voltage to adjust the transparency of the film. When power is off, liquid crystal molecules are arranged disorderly, blocking parallel light and presenting an opaque frosted state. When powered on, liquid crystal molecules align orderly under the electric field, allowing light to pass through and turning the film transparent. The light transmittance can also be steplessly adjusted by changing the voltage level.
Working principle
When power is off, liquid crystal molecules are arranged disorderly, blocking parallel light (frosted / opaque). When powered on, molecules align under the electric field and the film turns transparent. Transmittance can be steplessly adjusted by voltage.

Product features
Protect privacy
When powered on, light transmittance reaches up to 90% with haze as low as ~4%. When powered off, haze exceeds 90%, protecting privacy to the fullest extent.
Rear projection imaging carrier
Project images onto the dimmable film for unobstructed viewing and advertising venue deployment.
Safety & explosion-proof
Composite adhesive with strong self-adhesion helps prevent glass splattering if broken, delivering explosion-proof performance.
Heat insulation & UV blocking
Blocks up to 99.9% UV rays and up to 80% infrared rays for solar control performance.
Energy-saving & eco-friendly
Transparent when powered on and frosted when off, with low daily power consumption. Also reduces renovation loss and pollution.
Effective sound insulation
Compared with ordinary glass, attaching dimmable film effectively enhances sound insulation and reduces noise interference.
