Optical Principle

The innovative Westglass PNLC Film Series (Reverse PDLC Technology) operates on a physical mechanism inverse to conventional PDLC films: it maintains high transparency at zero voltage by regulating liquid crystal molecular alignment, and triggers an optical scattering state when an electric field is applied, achieving two optical states of "transparent when power off, frosted when power on". This fundamentally reverses the operational logic of traditional PDLC films (frosted when power off/transparent when power on).

Featuring a self-adhesive patented structure, the film directly adheres to existing glass surfaces, enabling intelligent retrofits without removing original glass. Compared to replacing entire dimming glass, it saves 60%–75% on renovation costs and supports roll transportation (up to 50 meters), significantly reducing logistics costs and construction complexity. Ideal for commercial curtain walls, medical cleanrooms, high-end retail spaces, and smart home systems.
