SPATIALLY VARIABLE LIQUID CRYSTAL DIFFRACTION GRATINGS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18651052 titled 'SPATIALLY VARIABLE LIQUID CRYSTAL DIFFRACTION GRATINGS

The present disclosure pertains to augmented reality display systems incorporating diffraction gratings and methods of manufacturing them. A diffraction grating consists of multiple diffracting zones with a periodically repeating lateral dimension corresponding to a grating period for light diffraction. Additionally, the diffraction grating includes various liquid crystal layers corresponding to the different diffracting zones. These liquid crystal layers have liquid crystal molecules aligned differently, resulting in different optical properties associated with light diffraction.

Original Abstract Submitted

The present disclosure relates to display systems and, more particularly, to augmented reality display systems including diffraction grating(s), and methods of fabricating same. A diffraction grating includes a plurality of different diffracting zones having a periodically repeating lateral dimension corresponding to a grating period adapted for light diffraction. The diffraction grating additionally includes a plurality of different liquid crystal layers corresponding to the different diffracting zones. The different liquid crystal layers include liquid crystal molecules that are aligned differently, such that the different diffracting zones have different optical properties associated with light diffraction.
