Privacy Films for Curved Displays - A simplified explanation of the abstract
This abstract first appeared for US patent application 18484302 titled 'Privacy Films for Curved Displays
Simplified Explanation
The patent application describes a privacy film that can be used on displays to control the viewing angle and prevent unauthorized viewing. The film consists of a light-blocking layer with opaque and transparent portions, which are strategically shaped to direct light only towards the primary viewer. The film is designed to cover curved displays, with opaque portions extending along different angles relative to the transparent substrates. Additionally, the privacy film may include a light-redirecting layer, such as a prism or liquid crystal layer.
- The privacy film is designed to be used on displays to protect sensitive information from being viewed by unauthorized individuals.
- The light-blocking layer of the film consists of opaque and transparent portions.
- The opaque portions are shaped in a way that ensures light from the display is directed only towards the primary viewer.
- The privacy film is suitable for covering curved displays, with opaque portions extending along different angles relative to the transparent substrates.
- A light-redirecting layer, such as a prism or liquid crystal layer, may be included in the privacy film to further enhance its functionality.
Potential Applications
- Privacy films for electronic devices, such as smartphones, tablets, and laptops, to protect sensitive information in public settings.
- Privacy films for computer monitors in offices or shared workspaces to prevent unauthorized viewing of confidential data.
- Privacy films for ATMs or self-service kiosks to ensure privacy during transactions.
Problems Solved
- Prevents unauthorized viewing of sensitive information displayed on electronic devices or monitors.
- Provides privacy in public settings where multiple individuals may be viewing the same display.
- Allows for the use of curved displays without compromising privacy.
Benefits
- Enhanced privacy and security for individuals using electronic devices or monitors.
- Versatile design that can be applied to various types of displays, including curved ones.
- Customizable viewing angles to ensure that only the intended viewer can see the displayed content.
Original Abstract Submitted
A privacy film may have a light-blocking layer that is interposed between first and second transparent substrates. The light-blocking layer may have a plurality of opaque portions and a plurality of transparent portions. The opaque portions may be shaped to ensure light from the display is directed only to the primary viewer of the display. Each opaque portion of the light-blocking layer may extend along a respective longitudinal axis between the first and second transparent substrates. Privacy films used to cover curved displays may have opaque portions that extend along longitudinal axes that have different angles relative to the transparent substrates. Opaque portions in the edge of the privacy film may have longitudinal axes that are at non-perpendicular angles with respect to the transparent substrates. A privacy film for a curved display may also include a light-redirecting layer such as a prism layer or a liquid crystal layer.
