The privacy screen protector is a film that prevents others from peeking . Its main functions are: protection of privacy, prevention of loss, usually used on the display screen, and protection of the information on the screen. The screen information is visible on the front side, and the screen information is not visible on the side to prevent others from seeing the contents of the screen, thus protecting their privacy. So how does a privacy screen protector work?

　　The privacy screen protector is controlled by the angle of the light, and the wide viewing angle of the screen (such as the 175 degree angle of view of the measuring instrument) is changed to a narrow viewing angle (30 degrees); realized by a side-by-side arrangement of the light shed structure, at a certain The angle, through the light blocked by the light shed, can not pass; the light shed is made by resin and color paste rolling through the mold to solidify, showing grayish black; the interval of the light shed is usually 0.02 ~ 0.1mm.

　　Through the privacy screen protector diagram, you can see that the smaller the viewing angle, the better the anti-spying effect. A good anti-spy film requirement is better for the anti-peep effect, and the second requires a higher light transmittance. In addition, the anti-peep film must have no streaks on the surface, no black spots, no scratches on the surface.

　　At present, the privacy screen protector can be divided into: 25 degrees left and right viewing angle: left stone 30 degrees can be viewed from the left, 45 degrees left stone. In order to prevent peeks, it can be divided into: left and right defense (ie 180 degree defense): four-sided defense (ie 360 degree defense, up and down, left and right sides).The thickness of the anti-peep film is 0.15mm-o6mm.
