SPATIALLY VARIABLE LIQUID CRYSTAL DIFFRACTION GRATINGS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240280851 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 diffracting zones, each with liquid crystal molecules aligned differently to give the zones distinct optical properties related to light diffraction.
