Product Overview
The Westglass Light Gray PDLC Self-Adhesive Smart Dimming Film utilizes Polymer-Dispersed Liquid Crystal (PDLC) technology to achieve instant switching between clear and frosted states by controlling liquid crystal molecular alignment via electric fields. It presents a soft light gray opaque effect, effectively blocking line of sight while maintaining natural daylighting for privacy protection.
With a self-adhesive design, this film directly applies to glass surfaces without complex installation, upgrading ordinary glass with smart functionality. The light gray tone combines basic dimming performance with a soft, premium texture, suitable for modern aesthetic and functional integration in high-end commercial spaces, smart homes, car sunroofs, and more.

- Enhanced Visual Layers: Light gray background improves projection contrast and depth.
3. Energy Efficiency & Eco-Comfort
- Full-Spectrum Blocking: 99% UV and >60% IR rejection reduces heat radiation and AC energy use while protecting furniture from aging.
- Low Power Design: ~5W/m² consumption, stable 24/7 operation with >80,000-hour lifespan.
4. Safety & Durability
- Impact-Resistant Film: Holds shattered glass fragments, compliant with safety standards for high-traffic areas.
- Wide Temperature Range: Operates in -10℃~65℃ climates.
5. Tool-Free Installation & Smart Control
- Peel-and-Stick Design: Optical-grade adhesive fits curved glass, leaves no residue when removed—perfect for retrofits.
- Multi-Control Compatibility: Works with physical switches, remotes, voice commands, apps, and smart home systems for one-touch modes (e.g., "movie mode" vs. "meeting mode").
Technical Highlights
