What is a privacy filter?
The privacy filter, that is, the "left and right anti-peep film" is also called the anti-peep protection film, which means that the front side looks at 0 degrees and the anti-peeping blur becomes 10-15 degrees to the left (or 10-15 degrees to the right). Lower, until the left side 30-40 degrees (or 30-40 degrees to the right), basically can not see the picture.
What is the principle of a monitor privacy filter?
The monitor privacy filter utilizes the optical principle of physics, and adopts an ultra-fine louver structure, which can make the range of light reflected on the display screen smaller, and most of the light returns only in the incident direction. Therefore, only the user who is facing the screen can receive this part of the light and see the contents on the screen. Bystanders who are at an angle to the screen can't receive the light reflected from the screen from the side, so even if they look at the screen, they can only see a dark.
What is the structure of monitor privacy filter?
The thickness of the monitor privacy filter is generally between 0.3 and 0.60 mm. It consists of five coatings: PET layer, adhesive layer, ultra-fine louver, PC layer, anti-glare hard coating. The ultra-fine louver material in the anti-peep film is made up of multi-layer materials. The louver is permanently set at the full-open (edge) position. There are about 715 louvers per inch (25.4 mm), each of which has a complete anti-spy film. Thousands of miniature blinds. The louver material consists of a grid structure arranged side by side. The spacing of the gratings is between 0.02 and 0.1 mm. When the light is irradiated on the privacy film, most of the light is blocked by the grating, and only a small portion is substantially vertically irradiated on the film. Light can be reflected out of the interval, which can reduce the visibility of the screen and prevent peeks.
What are the advantages and disadvantages of the monitor privacy filter?
Monitor privacy filter advantages:
1.Protect privacy to prevent voyeurism: Using the principle of physical optics polarization, after using the anti-spy film on your LCD screen, the screen only has visibility of 30 degrees or less on the front and side, and from the side 30 degrees away from the left and right. I can't see the screen content.
(The blinds should be known to everyone, a vertical line, 30 degrees away means that when viewed from the left, 30 degrees away from the left side of the screen (left line), when viewed from the right side, 30 degrees away from the right side of the screen (right line) ).
2. Prevent scratching: The outer surface layer is treated with super-abrasive material coating, and the hardness is 4-5H, which can effectively prevent scratches, stains, fingerprints and dust, and protect your love machine from external damage to a large extent.
3. Flexible application: When the computer does not need anti-peep, it can be easily removed as a computer accessory, even if the laptop is not taken down on the notebook screen, it can be closed freely.
4. Prevent warm reflection: frosted surface, anti-reflective, prevent sunlight, fluorescent lights, etc., prevent strong glare from reaching 99.9% to eliminate eye fatigue and protect eyes.
5. UV protection up to 96%, anti-radiation up to 99.9%, anti-static, enhance contrast, make the effect better.
Disadvantages of monitor privacy filter:
1. There is a small "blade" structure in the anti-spy film lens. This special structure blocks some light. Even if you look at the screen from the front, you still feel that the screen is darker than before, so the brightness and color of the screen will be affected to some extent.
2. The screen's automatic brightness control with anti-spy film is not 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.
3. A long time staring at the screen can lead to refractive errors or visual dysfunction, as well as the possibility of inducing disturbances in the nervous system and the body's biological clock.

What is an anti-glare screen protector?
The anti-glare film is made of a metal material such as nickel or silver, and these metals are placed in a high-speed moving ion state in a vacuum environment to adhere to the glass surface. A screen protector that reduces the glare of the screen and protects the eyes. According to the reflection mode of glare, it can be divided into: mask reflection and reflection glare. Shading reflection refers to superimposing the surface of a regularly reflected image of approximately diffuse reflection such that the contrast of the observed object is reduced and the observed object is partially or completely disturbed. Reflected glare is usually associated with the position and angle of the viewer and is produced by highly smooth specularly reflected light.
What is the structure of the anti-glare screen protector?
The anti-glare film is made of PET material and can be securely attached to the screen. The anti-glare film contains a protective layer from top to bottom.
