Many readers should feel that there's always someone staring at your screen when you're using your phone on the subway, bus, or other public place. While they may not have other malicious ideas, we still don't like strangers seeing our screen content, in which case we use a privacy film to achieve this. Today, Xiaobian will introduce to you the advantages and disadvantages of privacy film.

​

The privacy film uses micro shutter optical technology and provides a 60-degree clear screen display in the front. The side is 180 degrees dark, so as to achieve the purpose of protecting your privacy. Its principle is similar to vertical blinds, when you stand in front of the open vertical blinds, you can see the scenery in front of you at a glance. But when you stand on one side, the view from the window is blocked. The shutters of the Privacy Film Protector have thin enough blades and embed hundreds of blades into the film so that the front view is unaffected and the screen is slightly darker when viewing angles are slightly sideways.

According to the installation method, the privacy film can be divided into: ordinary privacy film, adhesive privacy film, hanging privacy film, magnetic privacy film, etc.

The ordinary privacy film is the silicone strip of the monitor frame and the slide-in bracket are included in the scope of supply. In this way, the filter can be easily removed and reused.

Adhesive privacy film is also called electrostatic adsorption privacy film: due to the silicone layer, it can be adhered to the entire screen, suitable for permanent privacy protection, and can guarantee no bubbling and residue.

Magnetic Privacy Film: Can be fastened in seconds and easy to remove and reuse. Magnet solutions are available for MacBooks and other devices with metal casings.

In addition to the privacy protection function, the privacy film has two advantages: it can protect the sensitive glass surface from damage and scratches without affecting the touch function. They also feature a special anti-blue light coating that reduces high-energy short-wave blue light hitting the eyes directly.

So what are the disadvantages of privacy film?

The privacy protection lens has a small "blade" structure. This special structure blocks some light. Even if you look at the screen from the front, you will still feel that the screen is darker than before, so the brightness and color of the screen will be affected to some extent.

In addition, the automatic brightness control of the phone with the privacy film will not be as sensitive as before, because the original brightness is not bright enough after applying the film, so you need to manually adjust to increase the screen brightness, which will consume more power.
