Product Overview

The Westglass PNLC Film Series (Reverse Smart Dimming Film) is a breakthrough electro-optical material featuring an innovative "Reverse Smart PDLC Film Control Logic"—remaining highly transparent when powered off and instantly frosting to a privacy-protecting matte state when powered on. Built on polymer network liquid crystal (PNLC) technology, it combines flexible ITO conductive films with high-toughness PET substrates to precisely regulate liquid crystal molecular alignment via electric fields. This enables instantaneous switching between a power-off transparent state (transmittance ≥88%) and a power-on frosted state (transmittance ≤12%), delivering dual functions of privacy shielding and light control.

Unlike traditional PDLC dimming films, this product redefines industry standards with its "transparent when off" design, maintaining natural clarity without power and eliminating the long-term power consumption of conventional smart films. Its self-adhesive installation allows direct application to glass, acrylic, and other substrates without structural modification, retrofitting ordinary glass with smart dimming capabilities. Widely used in architectural curtain walls, smart homes, commercial displays, and transportation.
