The privacy filter is a patented ultra-fine louver optical technology that is unique in the world. Only the front side can see the content, and the side is completely invisible, preventing the nearby people from peeking at the protective film of your screen content. The existing anti-slip film products are combined with the original anti-reflective film, anti-UV film, mirror film and anti-radiation film.

　　Whether you want to protect your bank details, your company's marketing plan, or a private photo album, privacy filter also allows you to use it anywhere, without worrying about peeks.

　　The YIPI privacy filter has the benefit of reducing glare, making it easier to see the screen in low-light rooms. In addition, it reduces the viewing angle of the screen to 45 degrees. This prevents boring people from viewing your private information. It can be applied to exams and they can prevent cheating.
