Does PDLC smart glass conduct electricity?

No, the internal PDLC layer is plastic and does not conduct electricity, since it is electrically insulated. Rather, it behaves more like a capacitor, where the applied signal alternates between positive and negative voltages at the plates of the capacitor, causing an alternating electric field throughout the PDLC dielectric, which is what aligns the liquid crystals with the frequency of the signal (normally 50 Hz or 60 Hz).

?

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.

Smart Sunroof Kit Installation Guide

Smart Sunroof Kit Installation Guide
​ 1. Preparation
Move the front seats forward and fold down the rear seats to create sufficient workspace.
Clean both the interior and exterior surfaces of the sunroof thoroughly, then wipe dry.
​ 2. Installation Steps
​ Step 1: Power Connection
Insert the kit’s power cable into the power outlet located in the trunk.
Remove the rubber trim above the trunk, thread a ​fish tape​ (wire guide) through the interior panel, and attach the power cable to the fish tape.
Pull the fish tape to route the power cable through the panel, then remove the fish tape.
​ Step 2: Bracket Assembly
Remove ​Bracket 1#​ from the rear of the kit.
Insert the black ​Z-shaped supports​ into both ends of Bracket 1#.
​ Note: Keep the right direction of the threaded holes on Bracket 1# and ​Z-shaped supports.
Secure the ​flat plate support​ to ​Bracket 2​# (front of the kit) using screws.
​ Note: The sloped side of the flat plate support must face toward Bracket 2#.
​ Step 3: Positioning the Kit
Install Bracket 1# beneath the sunroof glass, ensuring the pointed ends of the Z-shaped supports face the ​front of the vehicle.
Carefully maneuver the kit into the cabin through the trunk, ensuring:
Brackets face upward.
The end with Bracket 2# points toward the ​front of the vehicle.
Avoid scratching interior trim during placement.
​ Step 4: Mounting the Kit
Peel off the protective film from the bracket-side of the kit.
Lift the kit gently and insert the flat plate support on Bracket 2# into the gap beneath the sunroof glass.
Connect the cable to the kit.
Align the screw holes on the kit with those on Bracket 1#, then secure with screws. Install decorative caps over the screws.
Peel off the protective film from the underside of the kit.
​ Step 5: Cable Management
Tuck excess wiring under the trunk’s rubber trim for a clean finish.
​ 3. Final Checks & Testing
Verify all connections and bracket alignments.
Power on the kit and test dimming functionality.
Restore seats to their original positions.
Note:
Use only soft tools (e.g., nylon pry tools) to avoid interior damage.
Ensure threaded holes and connectors are fully engaged before tightening screws.

What is smart glass/film?

Smart glass/film is a switchable light control glass that turns a transparent glass to opaque instantaneously and vice versa.

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.
How to make smart glass?

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.
