METHODS AND APPARATUSES FOR IMPLEMENTING VARIED OPTICAL GRATING GEOMETRIES IN AN AUGMENTED REALITY DISPLAY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240134198 titled 'METHODS AND APPARATUSES FOR IMPLEMENTING VARIED OPTICAL GRATING GEOMETRIES IN AN AUGMENTED REALITY DISPLAY
Simplified Explanation
An augmented-reality (AR) eyewear display patent application abstract describes the use of an optical waveguide with multi-layered optical gratings to improve display quality and efficiency.
- The optical gratings in the waveguide have varying depths, slope angles, lengths, and/or widths to optimize optical characteristics for high resolution, contrast, display uniformity, input coupling efficiency, and output coupling efficiency.
- Different configurations of two-dimensional or three-dimensional gratings in the waveguide enable lower-power AR eyewear displays to achieve the same display quality as higher-power conventional displays.

Original Abstract Submitted
an augmented-reality (ar) eyewear display utilizes an optical waveguide having multi-layered optical gratings in a repeating arrangement. the optical gratings include varying depths, slope angles, lengths, and/or widths in order to tune the gratings to provide an improved ar eyewear display. by using the different configurations of two-dimensional or three-dimensional gratings disclosed herein in a waveguide of an ar eyewear display, optical characteristics of the waveguide are optimized to provide, e.g., high resolution and/or contrast, high display uniformity, high input coupling efficiency, and/or high output coupling efficiency. accordingly, in some embodiments, aspects of the present disclosure enable lower-power ar eyewear displays to produce the same quality of display of a higher-power conventional ar eyewear display waveguide.
