DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18294181 titled 'DISPLAY APPARATUS
The abstract describes a display apparatus designed to prevent unwanted images from being visually recognized by an observer and others.
- Image light generation apparatus generates image light
- Light guide plate guides image light to an eyeball
- Light guide plate main body includes light incident surface and optical surface group
- Reflection surface inside the light guide plate reflects image light to the eyeball
- Light-shielding portion shields stray light component of the image light
Potential Applications: - Privacy screens for electronic devices - Security displays for confidential information - Anti-spying technology for sensitive environments
Problems Solved: - Preventing unauthorized viewing of displayed content - Protecting sensitive information from prying eyes
Benefits: - Enhanced privacy and security for users - Improved confidentiality of displayed information
Commercial Applications: Title: Privacy Screen Technology for Enhanced Security Displays This technology can be used in electronic devices, ATM machines, and secure facilities to protect sensitive information from unauthorized viewing.
Questions about the technology: 1. How does the reflection surface inside the light guide plate contribute to preventing unwanted image recognition? - The reflection surface redirects the image light towards the eyeball, making it difficult for others to view the displayed content from different angles.
2. What is the significance of the light-shielding portion in the light guide plate? - The light-shielding portion helps to block stray light components, ensuring that only the intended viewer can see the displayed images clearly.
Original Abstract Submitted
To provide a display apparatus capable of preventing unwanted images from being visually recognized by an observer and others. A display apparatus according to the present technology includes: an image light generation apparatus that generates image light; and a light guide plate that guides the image light from the image light generation apparatus to an eyeball, in which the light guide plate includes a light guide plate main body including a light incident surface upon which the image light enters, and an optical surface group including a plurality of optical surfaces that guides the image light via the light incident surface, at least one reflection surface that is provided inside the light guide plate main body and reflects the image light via the optical surface group to a side of the eyeball, and at least one light-shielding portion that is provided in the light guide plate main body and shields a stray light component of the image light. In accordance with a display apparatus according to the present technology, a display apparatus capable of preventing unwanted images from being visually recognized by an observer and other people can be provided.
