Are PDLCs only available as artificial materials?

Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.

?

How much light does PDLC glass transmit?

When not connected to a voltage, typically the transmittance can be as low as 2%. When connected to a voltage, it can be up to 80%, but this maximum value varies from manufacturer to manufacturer.

?

Can smart glass be used in outdoor applications?

Yes, smart glass can be installed in outdoor areas as normal laminated glass.

?

Can smart glass/film be regulated to gradually change its state?

Yes, smart glass/film can be regulated to slowly transform from opaque to transparent or vice versa. A transformer with dimmer function is needed.

?

How long time does smart glass/film change from opaque to transparent?

Smart glass/film change in 1/100 second from opaque to transparent and 1/10 second from transparent to opaque.

what is the difference between self-adhesive smart film and smart glass

1. What is self-adhesive smart film and smart glass

Self-Adhesive Smart Film:

A flexible polymer-based film (typically PDLC: Polymer Dispersed Liquid Crystal) with an adhesive layer on one side. It is applied directly to existing glass surfaces like a sticker.

Smart Glass:

A laminated glass unit where PDLC film is permanently sandwiched between two layers of glass using EVA or PVB interlayers under high pressure/temperature. This creates a solid, structural glazing product.


2. Installation & Application

Feature Self-Adhesive Smart Film Smart Glass
Installation Peel-and-stick onto existing glass; DIY-friendly. Requires professional glazing; replaces entire glass unit.
Best For Retrofitting existing windows/glass partitions. New constructions or full renovations.
Complexity Some skill is needed:
1. How to install the film;
2. How to deal with the edge sealant;
3. How to hide the wire.

How to install the self-adhesive smart film?

Install the glass as the normal glass except for considering how to hide the wire.

3. Functionality & Performance

• Optical Clarity:
Both switch between transparent (ON) and opaque (OFF) via electricity. Smart Glass often has higher clarity due to glass encapsulation.

• Energy Efficiency:
Identical function: Blocks ~99% UV rays and reduces heat gain.
Power consumption is low (~5W/m²/hour).

• Durability:
Smart Glass is more robust (scratch resistant, impact-resistant, safety-glass properties, longer life time). Film is vulnerable to peeling/scratches comparing with smart glass.

• Safety:
Smart glass remains secure after breaking. Film lacks structural security but can prevent glass from shattering.


4. Applications

• Film: Ideal for retrofitting offices, shower doors, storefronts, or rental properties.

• Glass: Suited for high-end architectural projects (facades, security rooms, partitions), automotive sunroofs, and aviation.


5. Pros vs. Cons Summary

Type ✅ Pros ❌ Cons
Self-Adhesive Film Affordable, easy install, UV/heat blocking, retrofit-friendly Less durable, no structural safety, prone to air bubbles, Lower clarity than smart glass.
Smart Glass Premium finish, enhanced safety/durability, seamless integration, higher clarity and performance than film. High cost, inflexible for existing spaces, complex replacement.

Conclusion

Choose self-adhesive smart film for cost-effective, non-invasive upgrades to existing glass. Opt for smart glass in new builds or high-traffic areas demanding durability and safety. Both deliver dynamic privacy/energy savings but cater to different project scales and budgets.
