LIGHTGUIDE WITH POLARIZATION-SELECTIVE BULK REFLECTORS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18371780 titled 'LIGHTGUIDE WITH POLARIZATION-SELECTIVE BULK REFLECTORS

The abstract describes a lightguide with partially reflective slanted polarization-selective bulk mirrors that can be used in a near-eye display with a polarized image source. The mirrors reflect light of the polarized image source while fully transmitting light of the orthogonal polarization, making them less conspicuous to an external viewer while maintaining high efficiency in delivering the image light to the viewer.

• The lightguide features partially reflective slanted polarization-selective bulk mirrors.
• It is designed for use in near-eye displays with polarized image sources.
• The mirrors reflect light of the polarized image source and fully transmit light of the orthogonal polarization.
• This design reduces the visibility of the mirrors to external viewers while ensuring efficient delivery of the image light to the viewer.

Potential Applications: - Near-eye displays - Virtual reality headsets - Augmented reality glasses

Problems Solved: - Reduced visibility of mirrors in near-eye displays - Maintaining high efficiency in delivering image light to the viewer

Benefits: - Enhanced user experience in near-eye displays - Improved image quality - Reduced distractions for the viewer

Commercial Applications: Title: Enhanced Near-Eye Display Technology for Virtual Reality Headsets This technology can be used in the development of virtual reality headsets, enhancing the user experience and image quality. It can also be applied to augmented reality glasses, providing a more immersive and less distracting visual experience for users.

Questions about the technology: 1. How does the use of partially reflective slanted polarization-selective bulk mirrors improve the performance of near-eye displays? 2. What are the potential challenges in implementing this technology in commercial products?

Original Abstract Submitted

A lightguide with partially reflective slanted polarization-selective bulk mirrors is disclosed. The lightguide may be used in a near-eye display with a polarized image source. The polarization-selective bulk mirrors reflect light of the polarized image source, and fully transmit light of the orthogonal polarization, causing the mirrors to be less conspicuous to an external viewer while preserving high efficiency of delivery of the image light to the viewer.
