Introduction to Self-adhesive Switchable Film


Self-Adhesive Switchable Film, consist of protective film, ITO film and liquid crystal polymer(LCP),
 can make glass transmitted from transparent to opaque by supply voltage, like the smart 
switchable glass. It is transparent when it is on while it is opaque when it is off. This film is 
better solution to installed ordinary glass or the project of the ordinary glass which needs to be
 projected because it can be sealed on the glass surface directly without removing the glass.


l Shielding for privacy: this film is an intelligent switchable film, sealed on glass directly, can 
transmit the light to scattering by supply voltage to present the glass with self-adhesive film.

l Energy saving and cost reducing: This film, sealed on the construction glass, has the 
characteristics of excellent heat resistance to reduce the interior solar energy and electricity
 energy of air-conditioner. 
The data shows that the construction energy consumption is more than 25% of the total
 energy consumption, and the energy consumption of windows and doors is about 50% 
of the construction energy consumption, even it loses 70% by the glass transmission. 
If the interior temperature reduced 1℃, the electric consumption would increase 6%. 
Therefore, the self-adhesive film can reduce the interior temperature when it is opaque 
while the outdoor temperature is ultra high.

Switchable Projection Film

1. DESCRIPTIONS:The switchable Transparent Glass (STG), which makes the public place disappear at once or 
emergefrom private place by the on-off switch in 1/10 second, is proceeded by lamination 
glass technique.

The Polymer Dispersed Liquid Crystal (PDLC) film, laminated by two pieces of ordinary float 
glass takes the advantage of electric induced transmission and scattering, to feature the STG
 transparent when power on and opaque when power off.



l Can become transparent when power on, opaque when power off;

l Can be instantly invisible in 1/10 second because of the fast response speed;

l To be safe from the STG impact crushed, the shards of glass is stuck to the laminated
 PDLC film in the middle to avoid the injury to people;

l To save electricity: No matter on or off, the room with STG is still bright under the privacy

l To shield more than 98% UV to avoid color fading or aging of the interior decorations
 as well as to protect people from the disease caused by UV;

l To insulate all kinds of noise to 38 decibels exceeded to the insulating glass, 
because of damping effect of the PDLC film;

l The heat insulation property reaches to Level 2;
