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

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.
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).
Yes, smart glass/film is a safety glass. Being laminated, it prevents scattering of glass fragments in case of breakage.
How to make the busbars for smart film?
Tools：Dust-free cloth, Square resistance meter, Tape measure, Alcohol, Solder, Scissors, Film spliter, Copper foil, Tape, Brush, Silver paste, Marker pen, Squeegee, Electric soldering iron, Heat gun,Pins, Pliers
Step1: Film preparation.Lay the smart film on the glass table.
Step2: Mark busbars position.Measure and mark the position of the busbar according to the drawings on the side that busbar to be installed. The distance between the two busbars is 5-10cm and each busbar should be as long as possible.
Step3: Cut upper layer PET.Align the edge of the smart film with the glass, start from one end with the film splitter, and cut the upper layer of PET to the marked position.
Step4: Wipe off liquid crystal. Use a dust-free cloth dipped in alcohol to wipe off the liquid crystal exposed after cutting off the PET.
Note: Wipe gently, not only to remove all the liquid crystal , but also not to damage the conductive ITO.
Step5: Check ITO resistance. Use the square resistance meter to select at least 3 different points to measure the ITO after wiping, and the value should be less than 250 ohm, otherwise, the ITO may be damaged and thus the smart film may not work properly.
Step6: Apply tape. Stick the tape at a distance of 5-6mm from the edge of the film to cover the liquid crystal between the lower layer of ITO and the upper layer of PET, so as to prevent the silver paste from applying this gap and causing a short circuit.
Step7: Apply silver paste evenly to cleaned ITO.
Step8: Dry the silver paste with the heat gun. The heating temperature is about 70-100℃.
Step9: Tear off the tape pasted after heating.
Step10: Apply the copper foil carefully on the dried silver paste.
Step12: Cut off the excess part of the copper foil. In order to avoid the edges from lifting, the sharp corners of both the copper foil and the smart film are cut off.
Step13: Turn the smart film over and make another busbar according to the previous steps.
Step14: Pinning: use pliers to drive the pin into the connecting copper foil and smart film to make sure the copper foil stay with smart film.At least 2 pins for each busbars.
Step15: Solder the leads: Use a soldering iron to solder leads of the suitable length on the pin.
Step16: Power-on test: 1. Continuous power-on, power-off cycle 10 times; 2. Continuous power-on for 20 minutes. After test, check if there's any defect such as over heat and black spots.
Step17: Roll up the smart film for transport or storage.
