WAVEGUIDE STRUCTURE FOR HEAD UP DISPLAYS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240345403 titled 'WAVEGUIDE STRUCTURE FOR HEAD UP DISPLAYS
Simplified Explanation: The patent application describes an optical waveguide for a head-up display with two optical input regions. Optical gratings direct light injected into the input regions towards an output region, where the light is trapped by total internal reflection. Beam splitters and other optical elements can expand the pupil in two dimensions, directing light from each input region to different areas of the output region.
- The optical waveguide has two optical input regions.
- Optical gratings direct light towards an output region.
- Total internal reflection traps the light in the waveguide.
- Beam splitters and other optical elements expand the pupil in two dimensions.
- Light from each input region is directed to different areas of the output region.
Potential Applications: 1. Head-up displays in automotive vehicles. 2. Augmented reality glasses. 3. Military aircraft cockpit displays.
Problems Solved: 1. Efficiently directing light in head-up displays. 2. Enhancing visibility and clarity of displayed information. 3. Optimizing the use of optical elements in display systems.
Benefits: 1. Improved visibility and clarity of displayed information. 2. Enhanced user experience in head-up displays. 3. Efficient use of optical elements for directing light.
Commercial Applications: Optical waveguides with multiple input regions can be used in various commercial applications such as automotive head-up displays, augmented reality glasses for consumer use, and military aircraft cockpit displays. This technology can enhance the user experience and improve the efficiency of displaying information in these applications.
Questions about Optical Waveguides: 1. How do optical waveguides improve the efficiency of head-up displays? 2. What are the potential commercial applications of optical waveguides with multiple input regions?
Original Abstract Submitted
an optical waveguide for a head-up display having two optical input regions. optical gratings direct light injected into the optical input regions toward an output region; the directed light is substantially trapped in the optical waveguide by total internal reflection. beam splitters and other optical elements can be provided to expand the pupil in two dimensions. light from each input region is directed to different areas of the output region.
