Features: 1. A HM privacy film that gives you a sense of security. 2. Using the ultra-fine blinds optical technology, the display screen with the anti-peep film is visible on the front side and the side is not visible. 3. Can effectively isolate 96% of UV radiation. The surface is scratch-resistant to protect your display screen. 4. Matte smooth, double-sided optional. Scrub anti-glare, smoother and more peek. 5. Effectively protect confidential information and personal privacy, making it safer to use your computer. 6. Privacy protection: It is made of micro-louver optical technology to prevent confidential data and information loss caused by the voyeurism of the computer when it is used. 7. Visual comfort: HM computer anti-spy film can effectively reduce screen glare and reflection 8. Clear picture: There are two choices of smooth surface and matte surface. Use smooth surface to make the image display clearer and not deformed. 9. Protect the screen: After use, it can prevent the LCD screen from being scratched and bruised. 10. Easy to use: easy to install, easy to remove, does not affect computer closure Specifications: Material: PET Aspect ratio: 16:10 Anti-glare layer: 5μm Substrate: 200μm Adhesive layer: 10μm Fit layer: 125μm Scratch resistant layer: 5μm Total thickness: 650μm Use layer thickness: 570μm Blind window spacing: 0.1mm Storage environment: (indoor ambient temperature) 25 degrees, (relative humidity) 25 degrees, or at normal temperature and humidity below 60 degrees Viewing angle: 60 degrees (30 degrees left and right) Deflection: 0 degrees Light transmittance: 85% Hardness: 5H Package List: 1 * Anti-penetration film 1 * alcohol bag 1 * dust cloth 1 * double-sided tape 1 * buckle Note: 1. About the eyes discomfort The anti-peeping principle of the anti-spy film is optical shutter technology. After installation, the brightness of the screen will drop by 20% to 30%. The change in screen brightness is difficult to adapt at one time. At this time, you can increase the brightness of the screen to the appropriate brightness. 2. How to improve the anti-peep effect There are three factors that affect the effect of the privacy film: 1) External light environment: The general anti-spy film effect is relatively weaker as the outer light is brighter. 2) Screen brightness: The general anti-spy film effect is relatively weakened as the screen brightness increases. Therefore, when using the anti-peep film, the screen brightness should not be too high, but it should not be too low, otherwise it will easily lead to eye fatigue. 3) Glossy matte: The peeping film is composed of glossy and matte surfaces. With a matte face, it can prevent glare and help protect your eyes. If the anti-spying effect is better, the light side is facing outward, so that the anti-peep effect can be improved. 1、A HM privacy film that gives you a sense of security. 2、Using the ultra-fine blinds optical technology, the display screen with the anti-peep film is visible on the front side and the side is not visible. 3、Can effectively isolate 96% of UV radiation.
