VIRTUAL REALITY DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240345306 titled 'VIRTUAL REALITY DISPLAY DEVICE
The abstract describes a thin virtual reality display device with a pancake lens to reduce leaked light. The device includes components such as an image display panel, absorptive linear polarizers, retardation layers, a reflective circular polarizer, a half mirror, and more, arranged in a specific order to achieve the desired functionality.
- The virtual reality display device features a unique design with a pancake lens to minimize light leakage.
- Components such as absorptive linear polarizers, retardation layers, and a reflective circular polarizer are strategically arranged to enhance performance.
- The reflective circular polarizer acts as a concave mirror when light is incident from the half mirror side, improving the overall display quality.
Potential Applications: - Virtual reality gaming - Medical simulations - Training and education programs
Problems Solved: - Minimization of light leakage in virtual reality displays - Enhanced image quality and clarity
Benefits: - Improved visual experience for users - Increased immersion in virtual environments
Commercial Applications: Title: Advanced Virtual Reality Display Device for Enhanced User Experience This technology can be utilized in the gaming industry, medical field, and educational sector to provide users with a more realistic and immersive virtual experience.
Questions about the technology: 1. How does the pancake lens in the virtual reality display device contribute to reducing light leakage? 2. What specific advantages does the reflective circular polarizer offer in enhancing image quality in virtual reality displays?
Original Abstract Submitted
provided is a thin virtual reality display device including a pancake lens where leaked light can be reduced. the virtual reality display device includes at least an image display panel, a first absorptive linear polarizer, a first retardation layer, a reflective circular polarizer, a half mirror, a second retardation layer, and a second absorptive linear polarizer in this order, in which the reflective circular polarizer has an action of a concave mirror with respect to a beam incident from the half mirror side.
