1. Different technologies: Stripe-free privacy film uses physical optical polarization technology. If a large number of stripes appear on the privacy film, this phenomenon is due to incorrect die-cutting alignment at the manufacturer.
2. The stripe-free privacy film uses physical optical polarization technology. After the protective film is pasted on the LCD screen, the screen only has visibility within 30 degrees from the front and sides, making the screen clearly visible from the front. , the visibility will be lower if there are stripes.
3. Prices are different: no screen content cannot be seen from the sides 30 degrees away from the left and right sides of the non-striped privacy film, and the price is higher than that with stripes, so you can choose according to your own preferences Shop.
Extended information:
The structure of the tempered privacy film is a combination of tempered glass and privacy film; the tempered glass can be screen-printed in color, or made into a curved or flat surface, such as 3D or 2.5D; The price of a privacy tempered film is determined by the difficulty of the process and the choice of privacy film material.
In addition, the structure of the privacy film is controlled by the angle of light, changing the wide viewing angle of the screen (such as the 175-degree viewing angle of the monitor) into a narrow viewing angle (30 degrees).
In addition, it is realized through the grating structure arranged side by side. At a certain angle, the light passing through is blocked by the grating and cannot pass through and cannot be seen. The grating is made of resin and color paste and is rolled and solidified through a mold. It appears gray-black.
