Privacy Protection Film

Privacy Protection Film, or Privacy Filter, is an optical film using micro-louver technology to limit viewing angle, ensuring the protection of personal information. By limiting the viewing angle, it prevents anyone from accessing your screen without your consent. Whether you're working on confidential documents, engaging in private video conferences, or simply browsing the internet, it provides the ultimate protection against unwanted attention.

Prochase offers exclusive optical technologies that not only ensure visual privacy and screen protection, but also maintain optimal display brightness and device performance for the intended user. Our privacy filters also block harmful blue light emitted by electronic devices. This helps reduce eye strain and improves sleep quality. Additionally, our privacy protection films have an anti-bacterial coating that effectively blocks over 99% of harmful bacteria without any negative impact on the body. Experience a noticeable difference in visual comfort as you engage with your devices for extended periods.
