Nano Cloaking Film, also called Anti-Spy Film is a innovative technology film, unlike regular privacy film. lt is an LED technology for glass on the wall that obscure contents and information from screen from outside view. It’s a high transparent film material with back adhesion which can be easily pasted on the glass surface. Anyone looking into the room from outside sees just a black screen, while everyone in the room can work freely with peace of mind.
Structure and Working Principle:
Polarizing film is an optical film that can selectively filter light waves. Its principle is to control the propagation direction of light by using the characteristics of polarized light.Basic structure of polarizing film. The polarizing film is mainly composed of polyvinyl alcohol (PVA) polarizing layer and protective layer (such as PET film).
The PVA film is stretched and dyed so that the molecules are aligned in a specific direction, thus having the ability to selectively transmit light.
Its structure typically comprises:
PVA polarizing layer: the core part, responsible for the generation of polarized light.
Protective layer: Mechanically and optically protects the PVA film, ensuring its weather resistance and stability.
Adhesive layer and functional coating: Structural adhesion is enhanced, while anti-glare, anti-blue light and other functions can be integrated.
