With the continuous development of the times, people have become accustomed to storing personal information or company information on mobile phones, computers and other devices. So when we use these smart devices, we need to be extra vigilant to those around us who may peek at our screen information at any time. The anti-spy film is based on the principle of ultra-fine louver, which narrows the viewing angle by controlling the light. So what is the angle of the monitor privacy filter: 45 degrees and 30 degrees which is better?

　　45 degree monitor privacy filter: using shutter technology, using the principle of physical optics and polarization, after using the anti-peep film on your LCD screen, the screen only has visibility of 45 degrees or less on the front and side, and 45 degrees from the left and right. On the side, you can't see the screen. When looking out from the front, the view in front of you can be seen at a glance; when looking from the side, the line of sight is completely obscured. The principle of the anti-spy film is similar to that of the blinds, which reduces the distance between the louver strips we see everyday, and implants hundreds of thousands of ultra-fine louver layers in a protective film in ultra-fine blinds. Under the influence of optical technology, the front side of the screen has the highest light transmittance, the strongest visibility, and the side other than 45 degrees, the transmittance is 0, and the screen content cannot be seen.

　　30 degree monitor privacy filter: through the angle control of the light, the wide viewing angle of the screen (such as the display 175 degree viewing angle) becomes a narrow viewing angle (30 degrees); realized by a side-by-side arrangement of the grating structure, at a certain Angle, the transmitted light is blocked by the grating, can not pass; the grating is made by resin and color paste rolling through the mold to solidify, showing grayish black; (the blinds should be known to everyone, a vertical line, 30 degrees away is When looking from the left and right sides, it is 30 degrees away from the leftmost (leftmost line) of the screen, and 30 degrees away from the far right (rightmost line) of the screen when viewed from the right.
