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.
