Smart glass/film change in 1/100 second from opaque to transparent and 1/10 second from transparent to opaque.
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. 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. • Optical Clarity: • Energy Efficiency: • Durability: • Safety: • 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. 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.1. What is self-adhesive smart film and smart glass

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

3. Functionality & Performance
Both switch between transparent (ON) and opaque (OFF) via electricity. Smart Glass often has higher clarity due to glass encapsulation.
Identical function: Blocks ~99% UV rays and reduces heat gain.
Power consumption is low (~5W/m²/hour).
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.
Smart glass remains secure after breaking. Film lacks structural security but can prevent glass from shattering.

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
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.

Yes, smart glass/film is a rear projector screen with wide viewing angles. Even from the side one can enjoy clear, beautiful images and also in bright locations with high functional projectors.
Smart glass/film is operated using 48-65VAC power supply. Transformer will be needed for 110-230V power source.
How To Install The Self-Adhesive Smart Film?
Step 1.Preparation of Smart Film
1.1 Take out the self-adhesive smart film from the package carefully.
1.2 Put the dust cloth to a dust-free open space unroll the smart film and lay it flat.
Step 2.Preparation of Glass
2.1 Check the glass and make sure if there are adhesive strips and any other obstacle on the edge of the glass.
2.2 If there are adhesive strips remove or cut off them around the glass.
2.3 Caution: Don't scratch the glass when you remove the strips.
2.4 Pick up the right film confirm the film size according to the size of glass.
2.5 Spray clean water or water with detergent on the glass.
2.6 Clean the glass with a blade make sure there's no dust or stain on the surface.
2.7 Wipe the water off the surface of glass.
2.8 Spray some water-free alcohol on the surface of the glass or use a clean cloth contained alcohol to wipe the surface of glass and the frame.
2.9 Make sure that the glass surface is clean and free of water.
Step 3.Film Installation
3.1 Take the film and peel off the protective liner for 5 centimeter.
3.2 Align the film with glass and press the film on the glass slowly.Press the film to the surface of glass a few times slowly with a squeezer.
3.3 Caution: Don't spry water or detergent solution on the glass or film during installation of smart film.
3.4 Peel off the protective liner slowly for 3 to 5 centimeter each time and press the film with squeezer.
3.5 Squeeze the film step by step and make sure there's no bubble left between the film and glass.Repeat the action continuously until the film installed.
3.6 In case there's bubble or dirt between the film and glass peel off the film from glass and remove the dirt.
3.7 If the dirt is on the film adhesive side take a knife or other tool to pick up the dirt.If the dirt is on the glass wipe the glass with a clean cloth with alcohol.
3.8 After removal of dirt press the film on the glass and squeeze it on the glass.
3.9 Caution：The self-adhesive film could be peel off several times and the adhesive will still work.However we don't recommend it for more than 3 times.
3.10 If the self-adhesive film is too big you can cut the film with scissor or knife to the correct size.
3.11 Wipe the cutting edge with a clean cloth with water-free alcohol to avoid short-circuiting caused by rough edge.
3.12 Check the installed smart film in case the bubble or dirt spot peel off the part and reinstall it.
Step 4.Wiring and Sealant
4.1 Connect the bus-bars with wires and wrap the wire joints with insulating tape.
4.2 Use Eva hot melt sealant to fix the wires to the edges of frame and film as designed.
4.3 Peel off the protective liner from the outside of smart film.
4.4 In order to prevent water from entering the self-adhesive film from the edge it is necessary to apply sealant on the edge.GE381 silicone Weather-proofing sealant is our recommended edge sealant.
Step 5.Final Cleaning
5.1 Clean the surroundings and enjoy the smart film.
