Privacy Filter is mainly based on the technology of physical optics polarization principle, by implanting hundreds of ultra-fine louvered layers of blades in the protective film, the range of light reflecting out from the incoming display becomes smaller. Most of the light only returns along the incoming direction, and the light transmission rate on the front side of the screen is the highest and the visibility is the strongest, while with the tilt of the angle, the transmission rate will gradually decline, and the screen will gradually become darker. In this way, people outside a certain angle on the side will not be able to see the content of the screen, thus achieving the purpose of protecting privacy. The application of privacy filter on the touch screen is mainly to protect the user's privacy and information security.
The main application occasions of touch screen with privacy filter:

What are the advantages of touchscreens with privacy filters?
1. Protecting privacy: Privacy filters protect the user's privacy by limiting the viewing angle of the screen so that only the front viewer can see the content of the screen, effectively preventing side peeping.
2. Improve security: In situations where sensitive information needs to be protected, such as financial institutions and healthcare organizations, privacy filters can prevent information leakage and improve overall security.
3. Improve user experience: Privacy filters can also reduce screen reflections and glare, improve screen visibility, and enable users to have a better user experience in both bright and dim environments. Some privacy filters also have an anti-blue light function, which can reduce the blue light emitted by the screen on the eyes.
4. Protecting the touch screen: Privacy filters can also be used as a layer of protective film, which can effectively prevent scratches, stains, fingerprints and dust, protect the touch screen from damage and extend its service life.
Precautions for using touch screen with privacy filter:
1. Compatibility: When choosing a privacy filter, you need to make sure that it is compatible with the touch screen device to avoid affecting the sensitivity and display effect of the touch screen.
2. Installation and Removal: The installation and removal of privacy filters should be simple and easy to avoid damage to the touch screen device.
3. Price and quality: The price of privacy filter is closely related to its function and quality. When choosing, you should select the suitable product according to the actual demand and economic conditions.
