WAVEGUIDE EDGE HAVING REDUCED REFLECTIVITY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240313140 titled 'WAVEGUIDE EDGE HAVING REDUCED REFLECTIVITY
The abstract describes an augmented reality system with a waveguide that guides light towards an edge surface, which includes a reflectivity-reducing film made of curable material on a dissolvable film.
- The waveguide has opposing light-guiding surfaces and an edge surface.
- Light is guided towards the edge surface.
- A reflectivity-reducing film is created using curable material on a dissolvable film.
- The cured material forms a structure that reduces reflectivity on the edge surface.
- Nanostructures on the edge surface further reduce reflectivity.
Potential Applications: - Augmented reality devices - Optical systems - Display technologies
Problems Solved: - Reducing reflectivity on edge surfaces - Enhancing image quality in augmented reality systems
Benefits: - Improved image clarity - Enhanced user experience - Optimal light guidance
Commercial Applications: Title: Enhanced Augmented Reality Systems for Improved Image Quality This technology can be used in augmented reality glasses, heads-up displays in vehicles, and other optical systems to enhance image quality and user experience.
Questions about Augmented Reality Systems: 1. How does the reflectivity-reducing film improve image quality in augmented reality systems? The reflectivity-reducing film reduces unwanted reflections on the edge surface, leading to clearer images for the user.
2. What are the potential commercial applications of this technology in the consumer market? This technology can be utilized in consumer augmented reality devices, heads-up displays in cars, and other optical systems to enhance visual performance and user experience.
Original Abstract Submitted
an augmented reality system can include a waveguide having an edge surface that extends between opposing light-guiding surfaces. the waveguide can guide light toward the edge surface. the waveguide can include a reflectivity-reducing film, such as an absorptive film or a photovoltaic film, disposed on the edge surface. to form the reflectivity-reducing film, curable material can be disposed onto a dissolvable film. the curable material can be cured while disposed on the dissolvable film such that the cured material forms a reflectivity-reducing structure on the dissolvable film. the dissolvable film can be dissolved such that the reflectivity-reducing structure remains intact as a reflectivity-reducing film that can be adhered to the edge surface, such as with a primer layer. the edge surface can include nanostructures, sized smaller than half a wavelength of the guided light, that can reduce a reflectivity of the edge surface.
