In-depth analysis and application sharing of display anti-peeping technology

What is privacy protection technology?

The core function of privacy protection technology is to precisely control the screen's viewing angle, limiting onscreen content to visible only within a specific viewing angle range. This technology is intended to protect user privacy and prevent bystanders from inadvertently viewing sensitive information on the screen. Privacy protection technology also helps reduce light pollution, which can affect visual comfort. By limiting the screen's viewing angle, privacy protection reduces the spread of light from the screen into the surrounding environment, thereby reducing the level of light pollution. Simply put, privacy protection technology is like adding an "invisibility cloak" to the screen, rendering the screen's content invisible outside a specific viewing angle.

Privacy protection technology has a wide range of applications. For example, in a hospital operating room, the lights are bright and the display screens are also very bright. If the screen brightness is too high, it may affect the surgeon's vision and increase interference with the procedure. Privacy protection technology can limit the screen's viewing range to a specific angle, making the screen content visible only to the operating staff.

For example, during surgery, a nurse needs to review patient data and operate the screen, while the attending surgeon, standing directly in front of the operating room, is completely unaffected by the screen's light pollution. This not only protects the doctor's vision but also makes surgical procedures safer and more efficient.

Another typical application scenario is driving. When driving at night, the illuminated central control screen can easily reflect light on the windshield, obstructing the driver's vision and posing a safety hazard. Screens with anti-privacy technology, however, prevent glare, ensuring the driver's vision remains unobstructed and preventing the effects of reflections.

Another use case is in banks, self-service counters, or open office spaces, where privacy screens can prevent others from viewing sensitive information. For example, when a customer is using an ATM, the screen is visible only to the person directly in front of them, preventing others from viewing their password or transaction details.
