Privacy film is the use of physical polarizing technology. After pasting it on the LCD, the screen only has the front and left and right sides. Visibility within 30 degrees, that is to say, the screen is clearly visible from the front, but from the side 30 degrees away from the left and right, you can only see the dark screen and cannot see the content on the screen clearly.

​

Privacy Film has a super-abrasive coating on its outer surface. It can effectively prevent scratches, stains, fingerprints and dust, and protect your love machine from external damage. The inner surface layer adopts the bonding surface silicon coating, and the silicon coating has the characteristics of joining and then separating without leaving any traces, and can be joined again. Prevent warm reflections, prevent glare caused by sunlight, fluorescent lights, etc. The surface of the notebook privacy film is AG processed, and it also blocks 96% of ultraviolet rays, protects the eyes from ultraviolet rays, prevents low-frequency radiation up to 99.9%, and has a reflectivity of 5.8%, reducing the surface reflection of lighting/external light. The surface is processed by AG to prevent the reflected light from spreading and shining.

Inferior privacy film: It takes about 65 degrees of deviation from the viewing angle, almost the line of sight and the mobile phone are nearly parallel, so that the black screen is blurred, then this is a fake privacy film. In fact, several layers of black film with frosted effect or bad polarizers are superimposed, resulting in the less ideal privacy protection effect. And the general touch response is not good, often there is a delay or no response.

High-quality privacy film: It adopts the advanced imported technology "blinds" principle. After the screen is pasted, when the light is illuminated vertically, the light will return along the incoming direction, and other angles cannot be reflected. So when someone wants to peek from the side, they can't see the screen content. Therefore, the screen can only be seen clearly from a frontal perspective, and it is difficult to see from other angles, and the touch is not affected.
