PROTECTION OF AUGMENTED REALITY (AR) DISPLAY IN NEAR-EYE DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240160023 titled 'PROTECTION OF AUGMENTED REALITY (AR) DISPLAY IN NEAR-EYE DISPLAY DEVICE

Simplified Explanation

The abstract describes a patent application for protecting display elements of an optical stack assembly in an augmented reality near-eye display device against ultraviolet and/or infrared exposure using protective coatings and photochromic coatings.

• Protective coatings are applied to various surfaces of the elements of the optical stack assembly to protect against UV and/or IR exposure.
• A photochromic coating can be used on one of the surfaces of the elements as an alternative or addition to the protective coatings.

Potential Applications

The technology described in the patent application could be applied in various industries such as:

• Augmented reality
• Virtual reality
• Wearable technology

Problems Solved

The technology addresses the following issues:

• Protecting display elements from UV and IR exposure
• Enhancing the durability and longevity of optical stack assemblies in near-eye display devices

Benefits

The benefits of this technology include:

• Improved performance and longevity of near-eye display devices
• Enhanced user experience with augmented reality applications
• Increased safety for users by reducing exposure to harmful UV and IR radiation

Potential Commercial Applications

The technology could be commercially applied in:

• Consumer electronics
• Medical devices
• Military equipment

Possible Prior Art

One possible prior art could be the use of protective coatings on optical elements in various display devices to enhance durability and performance.

How does the photochromic coating work in protecting against UV and IR exposure?

The patent application mentions the use of a photochromic coating as an alternative or addition to protective coatings. However, it does not provide detailed information on how the photochromic coating functions in protecting against UV and IR exposure.

Are there any specific materials mentioned for the protective coatings in the patent application?

The abstract mentions protective coatings but does not specify the materials used for these coatings. It would be helpful to know if there are any specific materials or compositions recommended for optimal protection against UV and IR exposure.

Original Abstract Submitted

a display element of an optical stack assembly in an augmented reality (ar) near-eye display device may be protected against ultraviolet (uv) and/or infrared (ir) exposure through one or more protective coatings on various surfaces of the elements of the optical stack assembly. a photochromic coating on one of the surfaces of the elements of the optical stack assembly may also be used instead of or in addition to the protective coatings.
