Smart glass & Smart glass film

Smart glass is a novel specialty optoelectronic glass product capable of switching between transparent and opaque states. Below is a detailed introduction:
Definition and Structure
Smart glass is a laminated glass structure formed by bonding a liquid crystal film between two glass layers through high-temperature, high-pressure lamination.
Working Principle
When the power is off, the liquid crystal molecules within the glass are randomly dispersed, preventing light transmission and giving the glass an opaque appearance. When power is applied, the liquid crystal molecules align uniformly, allowing light to pass freely and instantly rendering the glass transparent.
Classification
By Control Method: Primarily divided into electrically controlled smart glass and thermally controlled smart glass. Electrically controlled dimmable glass adjusts transparency through power activation; thermochromic dimmable glass features a reversible thermochromic coating on standard glass, automatically regulating light transmission based on ambient temperature and solar radiation intensity.
By Surface Type: Includes colored dimmable glass, fire-resistant dimmable glass, and one-way vision dimmable glass. Colored smart glass offers multiple color options; fire-rated smart glass combines fire resistance with dimming functionality; one-way vision smart glass integrates one-way visibility with dimming effects.
Features
Privacy Protection: Enables real-time control over glass transparency to meet diverse privacy requirements across scenarios.
Safety Performance: Retains safety glass advantages, preventing shatter and ensuring impact resistance.
Environmental Protection: Provides thermal insulation, blocking over 99% of UV rays and over 98% of infrared radiation, safeguarding indoor furnishings and occupant health.
Sound Insulation: The dimming film and interlayer act as acoustic dampers, partially reducing noise transmission.
Projection Capability: Functions as a projection screen, delivering exceptionally clear images under suitable lighting conditions.
Application Scenarios
Commercial Applications: Suitable as glass walls or projection screens in conference rooms, or as partitions in office areas and monitoring rooms. Flexible transparency adjustment accommodates diverse usage needs.
Residential Applications: Ideal for balcony bay windows, interior space dividers, and bathroom partitions. Enhances spatial layout while ensuring privacy, and doubles as a home theater screen.
Medical Institutions: Replaces curtains for partitioning and privacy protection while offering safety, sound insulation, and eco-friendly maintenance.
Public Safety: Suitable for storefronts and counters in malls, banks, museums, etc. Instantly blurs visibility via remote control during emergencies to safeguard people and property.
Key Specifications
Thickness: Glass thickness typically ranges from 5.5mm to 40.5mm. Laminated product thickness varies based on glass thickness; e.g., 4+4mm smart glass laminated products measure approximately 9.5mm.
Light Transmittance: Visible light transmittance exceeds 78% when energized and >55% when de-energized.
Operating Voltage: Common voltages include 24VAC and 48VAC. Voltages exceeding 65VAC are considered non-safe.
Service Life: Normal lifespan exceeds 10 years, with a switching endurance of over 80 million cycles.
