What PDLC Can Do


Intelligent glass offers an instantly swift from transparent to opaque in various applications for privacy in offices, restaurants, hospitals, hotels and banks. The dimming glass are particularly popular for glass-walled or partitioned conference rooms in workspace or private homes based on open floor plans, or in hotel guestrooms where space is limited while privacy and elegance is required.

Safety & Security

The structure of PDLC privacy glass is like laminated safety glass. The film consist of PDLC formulation that is sealed between two panes of glass by interlayers (PVB or EVA). The intelligent glass prevents broken glass from scattering after a severe impact, keeping the window intact. The privacy glass meets safety glass standards and can be used in security and hurricane-resistant window applications.

Daylight control

Switchable privacy film is an active glass technology that switch the state with electricity for dynamic light control. The dimming film allows light to pass through for opacity or transparency by power on/off. By switching a window to its translucent state during peak sunlight, intelligent glass helps control interior room temperature and reduces the load on air conditioning systems, lowering energy costs.


Smart glass is dynamic, allowing a traditionally static material to become multifunctional and alive. Intelligent glass can be integrated into windows, partitions and other transparent surfaces, including architecture, automotive, retail windows and electronics. Privacy film/glass can transform a space from open and shared, to private and intimate. PDLC switchable film/glass also performs as a projection screen or a white-board.

Where To Use Smart Film & Glass


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.

What is the structure of PDLC glass?

PDLC smart glass is composed of :
Outermost panels of normal float glass (or sometimes acrylic) sandwiched around:
Inner panels of optically clear PET plastic (polyethylene terephthalate), sandwiched around:
ITO (Indium Tin Oxide) which is a transparent conductor, sandwiched around:
a PDLC core comprised of liquid crystal droplets, suspended in a polymer.

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.

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.
