EYEPIECES FOR AUGMENTED REALITY DISPLAY SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027767 titled 'EYEPIECES FOR AUGMENTED REALITY DISPLAY SYSTEM

Simplified Explanation

The abstract describes an eyepiece waveguide for an augmented reality display system. The waveguide includes an input coupling grating (ICG) region that couples an input beam into the substrate of the waveguide as a guided beam. A first combined pupil expander-extractor (CPE) grating region is formed on or in a surface of the substrate. This region receives the guided beam, creates a first plurality of diffracted beams at distributed locations, and out-couples a first plurality of output beams. Similarly, a second CPE grating region is formed on or in the opposite surface of the substrate, which also receives the guided beam, creates a second plurality of diffracted beams at distributed locations, and out-couples a second plurality of output beams.

• The eyepiece waveguide is designed for use in an augmented reality display system.
• It includes an input coupling grating (ICG) region that couples an input beam into the substrate as a guided beam.
• A first combined pupil expander-extractor (CPE) grating region is formed on or in the substrate's surface.
• The first CPE grating region receives the guided beam and creates a first plurality of diffracted beams at distributed locations.
• It also out-couples a first plurality of output beams.
• A second CPE grating region is formed on or in the opposite surface of the substrate.
• The second CPE grating region receives the guided beam and creates a second plurality of diffracted beams at distributed locations.
• It out-couples a second plurality of output beams.

Potential applications of this technology:

• Augmented reality displays
• Head-mounted displays
• Virtual reality systems

Problems solved by this technology:

• Efficiently coupling input beams into the eyepiece waveguide
• Creating multiple output beams for a wider field of view
• Distributing diffracted beams at various locations for optimal viewing

Benefits of this technology:

• Enhanced augmented reality experience
• Improved field of view
• Compact and lightweight design

Original Abstract Submitted

an eyepiece waveguide for an augmented reality display system. the eyepiece waveguide can include an input coupling grating (icg) region. the icg region can couple an input beam into the substrate of the eyepiece waveguide as a guided beam. a first combined pupil expander-extractor (cpe) grating region can be formed on or in a surface of the substrate. the first cpe grating region can receive the guided beam, create a first plurality of diffracted beams at a plurality of distributed locations, and out-couple a first plurality of output beams. the eyepiece waveguide can also include a second cpe grating region formed on or in the opposite surface of the substrate. the second cpe grating region can receive the guided beam, create a second plurality of diffracted beams at a plurality of distributed locations, and out-couple a second plurality of output beams.
