Anti-spy phone screen protector is an IQ tax? Then you must not have read this

I don’t know if you have this experience when you take the subway. Every time you play with your mobile phone, you can always feel some vague sights, showing that you are particularly interested in our mobile phone screen. It makes you feel very unhappy, but it's hard to say.

Because I am a stranger, sometimes I just pass it with patience. But there are always some "ignorant" people around you who are particularly interested in your mobile phone. They need to aim at chatting, playing games, and even taking selfies. They are everywhere! Playing with a mobile phone still prevents people from having privacy? Fortunately, there is a great invention turned out - anti-spy phone screen protector. Finally, these "screen peeping parties" can be dealt with calmly. Today, I will take everyone to understand how this "great invention" prevents peeping.
Can the anti-peeping phone screen protector really prevent peeping?

Many people are curious about the anti-peeping technology of phone tempered glass screen protector. Can a thin piece of phone tempered glass screen protector really prevent peeping?
Yes, the anti-spy phone screen protector uses microlouver technology, so that the content displayed on the screen is exclusively for the user to read from the front, and it is black when viewed from the side, just like the screen of the mobile phone is not lit. Thereby effectively protecting personal privacy in public places.

The principle of anti-peeping is to change the wide viewing angle of the screen (such as 175 degrees viewing angle) into a narrow viewing angle (30 degrees) through the control of the angle of light; The passing light is blocked by the grating and cannot pass through;
Therefore, the mobile phone with anti-spy phone screen protector can only clearly see the content displayed on the screen from the front, but from the side angle, it is like a black screen, and nothing can be seen. .
What is the difference between 25°, 30°, 45° privacy protection? Which is better?

If you have browsed the anti-spy phone screen protector on the e-commerce platform, you will know that the anti-spy phone screen protector is also distinguished by degree. Generally, there are three angle options of 25°, 30° and 45°. These three angles refer to viewing angles, that is, 30-degree viewing angles on the left and right, and 45-degree viewing angles on each side; the smaller the viewing angle, the larger the anti-peeping angle, so the better the anti-peeping effect.

At present, we are selling 30° anti-peeping phone screen protector, that is, when the front is facing the screen at 90°, the viewing range is only 30°, and the left and right sides, the line of sight beyond 30° can only see a black screen, so as to achieve the purpose of anti-peeping .
Why not choose 25° privacy phone screen protector? According to our personal experience, since the viewing range of 25° is too small, it is not as convenient as the 30° anti-peeping phone screen protector, so it is good for the anti-peeping angle to be appropriate, and it is not enough if it is too far.
In addition to anti-peep protection, the ordinary phone tempered glass screen protector has high-definition and wear-resistant features, which is equivalent to a phone tempered glass screen protector with an anti-peep buff. However, when purchasing a privacy screen, you still have to be cautious. If you accidentally buy a low-quality or fake privacy screen, the waste of money will be small, and the damage to the machine and eyes will be serious.
