Product Specification

Product Overview

The Smart Film (PDLC Film) Series from Westglass is a high-performance electro-optical product based on liquid crystal technology. By simply applying it to glass surfaces, it upgrades ordinary glass with the intelligent feature of "transparent when powered, frosted when unpowered". Using a liquid crystal polymer mixture sandwiched between transparent conductive films, the film operates as follows:

l   Unpowered: Liquid crystal molecules scatter randomly, creating a milky frosted effect.

l   Powered: Molecules align uniformly, achieving a light transmittance of 83%–91% (model-dependent), offering clarity comparable to standard glass.
No complex modifications are needed—immediately enhance glass functionality for architecture, automotive, medical, and commercial spaces.

Core Functions & Advantages

1. One-Touch Smart Control

l   Instant State Switching: 200ms ultra-fast response—powered transmittance 83%–91% (model-dependent), unpowered frosted transmittance < 5% for instant privacy.

l   Grayscale Adjustment (requires voltage regulator): Multi-level light control to balance natural light and privacy in any environment.

2. Privacy Redefined & Spatial Flexibility

l   Electronic Curtain Alternative: Replaces traditional fabric curtains for one-touch privacy in bathrooms, conference rooms, and medical observation windows.

l   Dynamic Partition Design: Transform residential dividers or hotel bathrooms into transparent/open or frosted/private spaces in seconds.

3. Flexible Fit & Effortless Installation

l   Self-Adhesive Film: Ultra-thin, flexible design adheres directly to tempered glass—no adhesive residue, works on curved glass for plug-and-play use.

l   Laminated Technology: Embedded between double glass (PVB/EVA composite) for higher transmittance and a 15-year lifespan, ideal for premium curtain walls.

4. Four Transmittance Options

l   83% / 86% / 89% / 91%: Cater to high-privacy to high-clarity needs, with visuals matching standard glass.

Product Highlights

1. Energy Efficiency:

l   Only 4–5W/m² power consumption, blocks ≥99% UV and ≥70% infrared rays, reducing AC energy use by 30%—compliant with green building standards.

2. Enhanced Projection:

l   Frosted state turns into a HD projection screen, perfect for commercial windows, home theaters, and conference presentations.

3. Explosion Resistance:

l   Laminated structure boosts impact resistance by 200%, with 100% fragment adhesion to eliminate splashing risks.

4. Long Lifespan:

l   High-molecular liquid crystal material and stable encapsulation ensure 100,000+ switching cycles without degradation, passing extreme temperature tests (-30°C to 80°C).

Typical Applications

1. Architecture

l   Smart windows for residential balconies and hotel bathrooms, enabling easy privacy-light balance.

l   Commercial curtain walls for daytime product display and nighttime projection ads, enhancing space value.

2. Automotive

l   Smart windows for sunroof shading and side window anti-glare, improving driving comfort and safety.

3. Medical

l   Frosted observation windows in operating rooms, balancing sterile environments with medical collaboration.

4. Commercial Innovation

l   Interactive storefronts: Transparent for product display, frosted for AR content to attract foot traffic.
