Privacy film is controlled by the angle of light, which changes the wide viewing angle of the screen (such as the 175-degree viewing angle of the monitor) into a narrow Viewing angle (30 degrees); realized by the light shed structure arranged side by side, at a certain angle, the light passing through is blocked by the light shed and cannot pass through; the light shed is prepared by mixing resin and color paste through mold rolling and curing. It is gray and black; the interval of the light booth is usually 0.02-0.1mm.

Currently available privacy films on the market can be divided into: left and right 25 degrees viewing angle: left stone 30 degrees viewing angle , the left stone is 45 degrees. The anti-peeping direction can be divided into: left and right protection (ie 180 degree protection): four-sided protection (ie 360 ​​degree protection, four sides up, down, left and right). The thickness of the privacy film is between 0.15mm-0.6mm. It can be seen from the schematic diagram of privacy protection that the smaller the viewing angle, the better the privacy protection effect. A good privacy film requires a good privacy protection effect, and the second requires a high light transmittance. In addition, the surface of the privacy film must not have stripes, no black spots, and no scratches on the surface.
