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.

- Low-Voltage Operation: Safe for diverse scenarios including homes and offices.
2. High Transparency & Instant Privacy
- 88% Transmittance When Off: Maximizes natural light and glass clarity.
- Instant Frosting (<20ms Response): Achieves immediate privacy, replacing traditional curtains or blinds.
3. Multi-Functional Adaptability
- Smart Control Options: Supports remote, voice, and APP control, compatible with smart home systems for seamless operation.
- Self-Adhesive Design: Directly applies to existing glass without complex installation, with customizable sizes (maximum width: 1.5m).
4. Eco-Friendly & Safe
- 99% UV Blocking & 60%+ Infrared Reduction: Protects furniture and reduces heat radiation.
- Safety Compliance: Shattered glass fragments adhere to the film, meeting safety glass standards and preventing splashes.
5. Versatile Applications
- Office Spaces: Transparent collaboration in meeting partitions, one-touch privacy mode.
- Home Design: Flexible light control for bathrooms, balconies, balancing natural light and privacy.
- Automotive & Commercial: Car sunroofs, window advertising screens, and projection functionality (works as a HD projection screen when power off).
