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. 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.ģ. 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.Ģ. This special structure blocks some light. There is a small "blade" structure in the anti-spy film lens. UV protection up to 96%, anti-radiation up to 99.9%, anti-static, enhance contrast, make the effect better.ġ. 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.ĥ. 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.Ĥ. 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.ģ. (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) ).Ģ. What are the advantages and disadvantages of the monitor privacy filter?ġ.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. Light can be reflected out of the interval, which can reduce the visibility of the screen and prevent peeks. 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. The spacing of the gratings is between 0.02 and 0.1 mm. The louver material consists of a grid structure arranged side by side. There are about 715 louvers per inch (25.4 mm), each of which has a complete anti-spy film. The louver is permanently set at the full-open (edge) position. The ultra-fine louver material in the anti-peep film is made up of multi-layer materials. #Monitor screen privacy protector Pc#It consists of five coatings: PET layer, adhesive layer, ultra-fine louver, PC layer, anti-glare hard coating. The thickness of the monitor privacy filter is generally between 0.3 and 0.60 mm. What is the structure of monitor privacy filter? 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. Therefore, only the user who is facing the screen can receive this part of the light and see the contents on the screen. 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. What is the principle of a monitor privacy filter? Lower, until the left side 30-40 degrees (or 30-40 degrees to the right), basically can not see the picture. 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).
