Privacy film is the use of ultra-fine shutter optical principle, through the angle control of light, the wide viewing angle of the screen (such as the monitor 175-degree viewing angle) ) into a narrow viewing angle (30 degrees); realized by the grating structure arranged side by side, at a certain angle, the transmitted light is blocked by the grating and cannot pass through; the grating is prepared by resin and color paste and rolled through the mold. Pressed and cured, showing gray-black;

​

The viewing angle of the privacy film is usually based on the screen as the middle baseline , the left and right have a viewing angle of 30~45 degrees, and the angle deviating from this viewing angle is an invisible angle (area); the smaller the viewing angle, the larger the anti-peeping angle, and the better the anti-peeping effect. Conversely, the larger the viewing angle, the smaller the anti-peep angle, and the worse the anti-peep effect. At present, the privacy protection effect on the market is 60 degrees, and the light will dim from 15 degrees.

The privacy film is currently on sale in two colors: Black Core Gold. Gold privacy film is better than black privacy protection, but black has anti-glare function.

If you often use it in the office, you can also use the gold privacy screen, which can improve the privacy effect by 30%.
