SWITCHABLE STRUCTURED ILLUMINATION GENERATOR, LIGHT GUIDE DISPLAY SYSTEM WITH STRAY LIGHT REDUCTION, AND STRESS-NEUTRAL OPTICAL COATING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240337785 titled 'SWITCHABLE STRUCTURED ILLUMINATION GENERATOR, LIGHT GUIDE DISPLAY SYSTEM WITH STRAY LIGHT REDUCTION, AND STRESS-NEUTRAL OPTICAL COATING
The patent application describes a device that utilizes a light guide to guide light via total internal reflection, with a reflective lens and a light absorption layer to manage the light propagation.
- Light guide guides light via total internal reflection
- Reflective lens at first surface of light guide
- Light absorption layer at non-parallel second surface
- Out-coupling element for output lights and stray light management
- Reflective lens redirects stray light to light absorption layer
Potential Applications: - Optical communication systems - Display technologies - Lighting systems
Problems Solved: - Efficient light propagation and management - Minimization of stray light interference
Benefits: - Improved light transmission efficiency - Enhanced control over light propagation - Reduction of stray light interference
Commercial Applications: Title: Advanced Optical Communication Systems This technology can be applied in optical communication systems, display technologies, and lighting systems, enhancing efficiency and performance in various commercial applications.
Questions about the technology: 1. How does the reflective lens help in managing stray light within the light guide? 2. What are the potential advantages of using a light absorption layer in this device?
Original Abstract Submitted
a device includes a light guide configured to guide a light to propagate inside the light guide via total internal reflection. the device also includes a reflective lens disposed at a first surface of the light guide. the device further includes a light absorption layer disposed at a second surface of the light guide that is non-parallel to the first surface. the device further includes an out-coupling element configured to couple a first portion of the light out of the light guide as one or more output lights, a second portion of the light that is not coupled out of the light guide becoming a stray light propagating inside the light guide toward the second surface. the reflective lens is configured to reflect the stray light toward the light absorption layer. the light absorption layer is configured to substantially absorb the stray light.
