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;

It is similar to vertical blinds, they are only visible when they are turned at an angle. Tiny polarized blinds, sometimes called micro-blinds, allow you to see what's on your computer screen, but not the people lurking to your left or right. The thinner the blind person, the more light is able to pass through the target user. Polarized plastic sheets use the same technology as privacy filters used in polarized glasses, where optical filters block light from specific angles. Depending on the make and model, computer privacy screens will often start blocking visibility at around 30-degree angles, and may show a black screen around 60-degree angles.

Privacy film is loved by consumers because of its function of protecting privacy, but many people stick a privacy film on the screen Afterwards, the screen will feel unclear and streaked, and some people may even feel dizzy and dizzy after using the privacy film. What is the reason?

Privacy film is the use of physical polarizing technology. After pasting it on the LCD, the screen only has the front and left and right sides. Visibility within 30 degrees, that is to say, the screen is clearly visible from the front, but from the side 30 degrees away from the left and right, you can only see the dark screen and cannot see the content on the screen clearly.

Because anti-peeping film has the function of anti-peeping, it is loved by customers, but because there is no unified standard at present, many inferior anti-peeping films are made Membranes flowed into the market. So what are the disadvantages of these inferior privacy films?

Privacy film is based on the principle of ultra-fine blinds, (blinds should be known to everyone, a vertical line can only be achieved at a specific angle See.) The physical polarizing technology makes the screen only have visibility within 30 degrees from the front and the side, and the content of the screen cannot be seen clearly from the sides other than 30 degrees from the left and right. So what are the types of anti-peeping films on the market?
