Core Functions

The PDLC (Polymer Dispersed Liquid Crystal) smart dimming film produced and sold by our company, westglass, is an intelligent optical material controlled by voltage, enabling instant switching between transparent and frosted states (response time as low as 200ms). Users can flexibly control light transmittance by adjusting the voltage, achieving multi-scenario applications such as privacy protection, energy saving, and projection screens.

With 8 years of production and sales experience, westglass offers:

• Customized electrode-equipped sheets (simply provide your window dimensions);
• Roll materials (30m×1.52m / 60m×1.52m / 100m×1.52m);
• Laser-cut special-shaped sheets for unique designs.

Product Advantages

1. One-Touch Privacy Control

• Frosted state when unpowered (haze > 95%), effectively blocking visibility—ideal for private spaces like living rooms, bedrooms, and bathrooms.

• Transparent and colorless when powered (light transmittance: 83% / 86% / 89% / 91%), ensuring unobstructed views.

2. Energy Efficiency & Thermal Insulation

• In frosted state, reflects visible light heat, blocks over 99% of UV rays, and over 85% of infrared rays, reducing indoor temperature and air conditioning energy consumption.

• Low power consumption of only 4–5W per square meter for significant energy savings.

3. Versatile Applications for Flexible Scenarios

• Projection Screen: Supports rear-projection, functioning as thermal-insulating glass during the day and transforming into a high-definition advertising screen or home theater screen at night.

• Smart Interaction: Compatible with mobile APP, voice control, sensors, and other smart home systems for seamless integration.

4. Safety, Durability & Easy Installation

• High impact resistance; laminated design prevents glass shattering and splashing upon impact.

• Ultra-long lifespan (no discoloration or peeling) with a wide operating temperature range (–20°C to 65°C).

• Self-adhesive design supports application to irregularly shaped glass, enabling DIY installation.

5. High Transparency & Aesthetic Flexibility

• Light transmittance exceeds 80% in transparent state, ensuring ample natural light without compromising brightness.

• Supports zoned dimming and color customization to enhance spatial design aesthetics.

Application Scenarios

• Residential: Bedroom partitions, bathroom doors/windows, smart curtains.

• Commercial: Office partitions, mall windows, hotel projection walls.

• Transportation: Car sunroofs, side window dimming (supports zoned control).

• Public Facilities: Hospital privacy glass, subway station partitions, museum display cases.

Installation & Maintenance

• Can be directly applied to existing glass surfaces without removing the original glass.

• Flexible substrate adapts to curved or irregularly shaped glass for versatile installation.

• Daily cleaning: Wipe with a soft cloth; avoid scratches from sharp objects.
