Core Principle

The Westglass PNLC Reverse Smart Dimming Film (Reverse PDLC Film) achieves intelligent switching between "transparent when power off" and "frosted when power on" through electric field control of liquid crystal molecular alignment, offering an inverse operation compared to traditional PDLC films (frosted when power off, transparent when power on).

With self-adhesive installation, it directly adheres to existing glass surfaces without requiring glass replacement, providing a more cost-effective solution than direct glass replacement while ensuring convenient transportation.
