Smart Dimming Glass for Automotive Applications

(Also referred to as PDLC dimming glass or electrochromic glass) is an advanced high-tech glass that adjusts its transparency via electrical current or light control. It offers the following key advantages:

1. Privacy Protection & Flexible Adjustment

  • One-Toggle Transparency/Frosted Effect: Instantly switches between clear and opaque states via electronic or optical control, ensuring cabin privacy (e.g., anti-peeping) while eliminating the need for conventional sunshades.

  • Zoned Dimming: Certain premium models support selective dimming (e.g., rear side windows only) to accommodate diverse needs.

2. Enhanced Comfort & Health Protection

  • Smart Sunshading: Automatically or manually modulates light transmission to reduce glare and block UV radiation (blocks over 80% of UV rays), lowering cabin temperature and improving ride comfort.

  • Anti-Glare: Minimizes glare from oncoming headlights at night or sunlight reflections during daytime, enhancing driving safety.

3. Energy Efficiency & Eco-Friendliness

  • Reduced AC Load: Cuts heat buildup from direct sunlight, indirectly lowering air conditioning consumption and extending EV range.

  • Sustainable Materials: Some variants eliminate the need for additional shading accessories, reducing material waste from traditional sunshades.

4. Futuristic Aesthetics & Design

  • High-Tech Appeal: Dynamic transitions between transparent and frosted states create a cutting-edge ambiance, elevating the vehicle’s premium feel (common in high-end EVs or commercial vehicles).

  • Streamlined Interior: Removes physical sunshades for a cleaner cabin layout.

5. Multifunctional Applications

  • Projection Screen: Frosted mode doubles as a display surface for in-car entertainment systems (e.g., rear-seat screens).

  • Shatterproof Safety: Laminated designs in some products prevent glass fragmentation upon impact, improving safety.

6. High Adaptability

  • Multiple Activation Modes: Supports manual buttons, light sensors, mobile apps, or voice control (e.g., integrated with smart cockpits).

  • Versatile Use Cases: Applicable to side windows, sunroofs, and rear windshields—ideal for panoramic roof models.

Potential Limitations

  • Higher Cost: Pricier than standard glass, primarily featured in mid-to-high-end vehicles.

  • Power Dependency: Requires continuous electricity to maintain state (though power consumption is typically low); malfunctions may disrupt functionality.

Representative Applications

  • EVs: Tesla Cybertruck (rear privacy glass), NIO ET7 (electrochromic sunroof).

  • Commercial Vehicles: Retrofitted rear privacy glass for business接待 (business接待: business reception).

Smart dimming glass is becoming a pivotal feature in automotive intelligence and comfort. As the technology matures, costs are expected to decline further.

Frequently Asked Question

Dimming film (also known as intelligent dimming film or PDLC film) is a kind of high-tech film material, which is able to change the light transmittance and realize the switching between transparent and opaque state through electric control, temperature control or light control. The following are its main advantages:

Instant switching: By current control (usually AC 12V-110V), it can quickly switch between transparent (light transmittance of about 70%~85%) and atomized (translucent or opaque) states, protecting privacy and eliminating the need for physical blocking.
No need for shades: replace traditional curtains or blinds to save space and enhance design simplicity.

Regulate light and heat: reduce direct sunlight, reduce indoor air-conditioning load, energy saving effect is remarkable (some cases can save energy consumption about 20%~30%).
UV Blocking: most dimming films block over 99% of UV rays, protecting indoor furniture and flooring from fading.

Architectural field: for smart windows, glass partitions, curtain walls, etc. Suitable for offices, hotels, hospitals and other places where dynamic privacy is required.
Automotive industry: used as sunroof or side window dimming layer, anti-glare and enhance privacy.
Commercial display: Combined with projection function, it can be used as transparent screen (e.g. window advertisement, exhibition interaction).

Explosion-proof and shatter-proof: The laminated design (e.g. composite with tempered glass) can enhance the strength of the glass and reduce the splash of debris when ruptured.
Long life: the life of high quality dimming film can reach 5~100,000 switching cycles with high stability.

Compatible with smart system: support mobile APP, voice control (such as Tmall Genie, HomeKit) or inductive control to integrate into smart home/office scenes. Touch control function: some high-end products support partition control to realize local transparency.

Light and transparent: the thickness is usually 0.1~0.5mm, which does not affect the original transparency of the glass, and can be customized in color or pattern.
Suitable for dust-free environment: medical, laboratory and other places with high requirements for cleanliness can reduce the problem of dust accumulation in the curtains.

Multiple lamination methods: can be attached directly to the existing glass (e.g. electrostatic lamination), or laminated in the glass (laminated process), lower cost when remodeling old buildings.
