How does smart glass/film works?

Smart glass works via electrical signal through activation of switches, sensors etc. Liquid crystal molecules turn to allow light to pass through and glass becomes transparent. It is opaque when not activated.

?

What is the maximum size of smart glass?

The maximum size of smart glass: 2000mm*6000mm (6.5ft*19.5ft).

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.

Why does PDLC require a polymer?

The polymer allows the liquid crystals to be embedded into a film, which can then be sandwiched between panels of glass or plastic. The polymer has constant optical properties which do not vary across its structure, and hence is considered isotropic.
In contrast, the liquid crystal itself is anisotropic, since its optical characteristics are not constant across its structure, but rather can vary under application of an electric field.

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.

Are the only states of PDLC just ON and OFF?

No, the transmittance (level of transparency) of the PDLC can be varied from 0% in the OFF state up to any value you want until you reach the maximum transmittance (normally 70% or 80%). This is done by simply altering the voltage from 0 VAC up to 70VAC, which is typically the maximum recommended voltage. This can be done electrically with a variable isolating transformer, or electronically with a switched-mode smart glass dimmer.

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.
