How do privacy screen protectors work?
The technical principle of the privacy screen protector is “Microlouver Technology“, and according to our further verification, this name should come from 3M company.
Although the technology of the privacy screen protector sounds very cool, it is actually not that complicated.
Its principle is simply similar to vertical blinds, when you stand in front of the opened vertical blinds, the scenery in front of you can be seen at a glance.But when you stand on the side, the scenery outside the window will be blocked by the blinds.
The privacy screen protector is to make the blades of the blinds thin enough, and embed hundreds of blades in a film, so that the front view is not affected, and the screen is slightly darker when the viewing angle is slightly sideways.
At this point, careful readers may find that, according to the principle, the privacy screen protector can only prevent the left and right from being peeped, but it will not affect the viewing experience of the screen in the up and down direction, that is to say, only the left and right sides will be non-visible with a viewing angle over 30°.
The technical principle of the anti-spy screen protector is simple, and the effect is quite good, so it has been favored by many computer and mobile phone users.
Does the privacy screen protector have shortcomings?
Although the privacy screen protector is effective, which is a simple and effective means of protecting your privacy, but its shortcomings are also very obvious.
After all, there is a small “blade” structure in the anti-peep film. This special structure will block some of the light. Even if you look at the screen from the front, you will still feel that the screen is darker than before, so that the brightness and color of the screen will be affected to a certain degree.
In addition, the automatic brightness control of the mobile phones with the privacy screen protector will not be as sensitive as before, because the original brightness is not bright enough after the film is applied, so you need to manually adjust to increase the screen brightness, which will cost more power consumption.
Finally, long-term viewing of the screen under dim brightness conditions has a negative impact on our vision. If you do need this screen protector to protect your privacy, we recommend you adjust the screen to the proper brightness when using it to avoid the screen being too dark.
