  The laptop privacy screen is popular among consumers because of its function of protecting private privacy, but many people will feel the screen is unclear and streaked after pasting the anti-spy film on the screen, and even some people use the anti-spy film. I feel dizzy and other symptoms. What is the reason?

  The laptop privacy screen is based on the micro-louver technology and the principle of physical optics. 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 from the left and right. Unable to see the screen content. The louver structure in the anti-spy film lens blocks some light. Let the user feel that the screen is darker than before, so the brightness and color of the screen will be affected to some extent.

  Staring at the screen for a long time, especially outdoors, the eyes will have symptoms such as stinging, tearing, and photophobia, which are mainly related to the visual fatigue caused by watching the mobile phone for a long time. The anti-peep film easily refracts the light of the screen, which increases the fatigue. Especially when outdoors, the screen illumination is insufficient, and it is more difficult to clearly see the font. Therefore, the ciliary muscles are often in a state of tension, the lens continues to maintain a large convexity, and the eyes are easily exhausted due to excessive adjustment. Over time, Will form or aggravate myopia.

  When the mobile phone anti-spy film is filmed, bubbles are generated, which makes it easy to enter the air and dust, which makes it impossible to see the pattern and subtitles on the screen, thereby affecting vision. To prevent air bubbles, when cleaning the film, first clean the dust and oil stains on your hands with a hand sanitizer, then wipe the surface of the phone with a cloth cloth or a soft cloth dampened with a small amount of water, clean the surface of the dust, fingerprints, etc.; Protect one side of the film, then align the top and left and right sides of the film; when filming, try to keep it at a constant speed. When bubbles appear, you can pull back some re-sticking, then use a wool felt scraper, or a soft pad The plate slowly presses the film a little on the surface of the phone. After the paste is finished, use a soft cloth just wiped the screen to wrap the credit card, etc., and slowly force the air bubbles off the edge.

  The choice of anti-spy film should first consider its light transmission. At present, the quality of anti-spy film on the market is uneven. Many merchants use inferior anti-peeping substrates to save cost. This film can not only effectively prevent peek The peeping of others will seriously affect the user's vision.

  When the laptop privacy screen is installed on the display screen, if a large number of stripes appear, this phenomenon is due to the fact that the die-cutting alignment is not good at the factory, and the angle is not set when the die-cutting is performed. A certain amount of material will reduce the output rate of the product if it needs to be angled, which will increase the cost of the manufacturer. Therefore, when selecting a peeping film, it is necessary to consider whether the anti-peep film manufacturer has the ability to strictly control the quality.
