Privacy Filters, Screen ProtectorsPrivacy filters and screen protectors are types of filters that are designed to protect the privacy of the user of a device, such as a computer or smartphone. Privacy filters are typically used on laptop and desktop computer screens, while screen protectors are used on smaller devices such as smartphones and tablets. Both types of filters work by limiting the viewing angle of the screen, so that only someone directly in front of the screen can see the content on it. This prevents others from seeing the screen from an angle and helps protect the user's privacy. In addition to privacy protection, privacy filters and screen protectors can also help protect the screen from scratches and other damage.
