Electronically controlled glass film, also known as switchable smart glass film, is a liquid Crystal functional film, also called electric curtain. Based on Polymer Dispersed Liquid Crystal technology, coating mixed liquid crystal and polymer to ITO conductive film, enable to turn from transparent to frosted under electricity. When power on the glass is clear which is as normal glass, when power off the glass is frosted to protect privacy.

About Switchable Smart Glass Film

Electronically controlled glass film, also known as switchable smart glass film, is a special glass film that can change its transparency at any time. The electronically controlled glass film consists of two layers of film with a layer of transparent glue in between. When an electric current is applied, the electronically controlled glass membrane can change from an opaque state to a transparent state, allowing different light rays to pass through it.

The working principle of the PDLC smart contril film is related to the electromagnetic field. When an electric current is passed through the electrically controlled glass membrane, an

electromagnetic field is generated and changes the molecular arrangement of the membrane. This change in molecular arrangement changes the transparency of the electronically

controlled glass film.

Specifically, the electronically controlled glass film consists of two layers of glass film and a layer of transparent glue. Conductive layers in electrically controlled glass films generate

an electromagnetic field when an electric current is applied. This electromagnetic field will change the molecular arrangement of the glass film that makes the electrically controlled

glass membrane, making the otherwise impenetrable glass transparent.

How to connect Switchable Smart Glass Film?

Connect Bus bar to Switchable Film

a Bus bar is an electrically conductive rod, bar, or strip.

In relation to Smart Film the Bus-bar is a conductive copper strip applied to one or two edges of the sheet of PDLC film prior to it being laminated between two panes of glass.

The copper strip acts as the conduit for the stepped-down (48/60V AC) electrical current which activates the liquid crystals within the film. The current is spread by means of a conductive Indium Tin Oxide coating on the surface of the enclosing PET film.

Some Smart Film panels may require more than one Bus bar to ensure full and even distribution of the electrical current.

Twin Wires

Wires are soldered on to either end of each Bus bar. They are twin (or dual) wires. This apparent ‘double-up’ is to compensate in the case of a wire becoming detached or dislodged during the panel’s installation process. The busbar may be applied to the long or short edge/s, depending on your requirements. Some panels, depending on their proportions, may require two bus bars. Acceptable Positioning of Bus bars on Smart Film Panel

Tools Preparation

Nitrile gloves (or other non-powdered, lint-free gloves)
Glass cleaner (non-ammonia based)
Silicone adhesive sealant
Applicator squeegee/Glass scraper
Rubber Roller
Lint free cloth (microfiber)
Low adhesive tape (painters tape)
Packaging tape
Wire mold / trim
Ladder (if necessary)
Electrical tester (switch cord)
Soldering iron
Electrical wire leads

Inspect each piece of film immediately, without wrong sizes, damaged edges and then proceed installation.

Cleaning window or door existing glass

Use a window scraper or blade to remove and dirt / blemishes from the glass surface. Repeat it without any dirt/blemisheds. And then Spray the glass with glass cleanser and clean with a absorbent cloth to completely clean and dry. Then Using a lint free cloth, wipe the glass surface until it is dust free.

size of tearing the covered film

Using a lint-free cloth, wipe down the protective liner on the cling side of film to remove any dust.

5
size of tearing the covered film
Put on clean nitrile protective gloves and using the edge tab of the label remove the first 100mm(4″) of the protective liner covering the cling side. Make sure that dust does not fall onto the cling Sid
6
Sticking film
Align the edge of Film with the top edge of the glass. When in position, run your finger along to press down and fix the top edge(the adhesive strip will hold the film in position).e.
7
sticking cautions
Gradually pull away the protective liner and allow Film to slowly adhere to the glass surface under its own pressure. Using the soft edge squeegee move down Film working in horizontal lines left to right to disperse any air bubbles. If any small bubbles are still visible, carefully lift the film and let it sit back down under its own pressure. If any small bubbles are visible, carefully check for any dust particles. If so, use adhesive tap and carefully remove the dust particles. Otherwise, carefully lift Film and let it sit back down under its own pressure (whilst-using the squeegee).
Repeat the above process until you have a bubble-free installation (for bubbles near the edges).

8
Soldering and circuit connection
Once Film is in place, connect Clips-On electrode to the transformer. For best results, use cable guides along the edge of the window.
9
Testing
Connect the transformer to the power source and test Film(switching from opaque to clear).
10
silicone sealant of the edge
For additional security or when using film in a high moisture environment use non-acidic based silicone(e.g. GE-83)along the edges of the film about 5mm, when it dries(about 3 days) later to power on and use the switchable film.
11
With 3M glue to seal the edge
Kind notice:
1,No water using in installation unless for clean the glass
2,The needed film size is 2-3mm less than the glass size to fit installation
3,All should be done under dust-free working environment.
4, Remember to use silicone sealant glue

Production of Switchable Smart Glass Film

switchable smart film

Application field of PDLC switchable smart glass film:

1. Construction field: Electronically controlled glass film can be used for glass curtain wall or partition wall, which can meet the balance between privacy protection and transparency.
2. Automotive field: Electronically controlled glass film can be used in car windows, which can control transparency according to needs, and can also enhance privacy and prevent ultraviolet radiation.
3. Medical field: Electronically controlled glass film can be used for operating room doors and partitions, and the degree of transparency and privacy protection can be adjusted according to needs to improve the safety of the operation process.
4.Home furnishing field: Electronically controlled glass film can be used for bathroom doors or bedroom partitions, which can control transparency and protect privacy.
