PDLC Smart Dimming Film
Polymer-dispersed liquid crystal film — transparent when powered on, frosted when off. Stepless dimming by voltage.
Transparent or private in one second
Switchable smart film — instant privacy for offices, hotels, and vehicles.
Product introduction
PDLC technology & working principle
PDLC smart dimming film is formed by coating liquid crystal polymer between flexible ITO conductive films. Voltage controls LC alignment: power on aligns molecules for transparency; power off scatters light for a frosted privacy state. Transmittance can be steplessly adjusted by voltage.
Working principle
When power is off, liquid crystals are disordered and scatter light (opaque). When powered on, crystals align and allow light through (transparent).

Product models
There are 5 product series of dimming film, among which CH-R2-12 and CH-G2Z are the flagship products.

Product features
Protect privacy
Up to ~90% light transmittance and low haze when powered on; haze exceeds 90% when off for maximum privacy.
Rear projection carrier
Suitable as a projection surface for advertising or presentation when in the opaque state.
Safety & explosion-proof
Composite adhesive helps retain glass fragments and improves impact resistance (patented structure).
Heat insulation & UV blocking
Blocks up to 99.9% UV and up to 80% infrared — patented solar control performance.
Energy-saving & eco-friendly
Low daily power consumption; reduces renovation waste vs. replacing glass.
Effective sound insulation
Enhances acoustic performance compared with ordinary single glazing.
