Liquid Crystal Polarization Volume Holograms Drive Breakthroughs in XR Near-Eye Displays

This presentation focuses on the applications of Polarization Volume Gratings (PVG) in AR waveguides, Pancharatnam–Berry Phase Lenses (PBL) in VR systems, and Polarization Volume Holograms (PVH) in XR near-eye display applications. It provides a systematic overview of their fundamental operating principles and fabrication methods, and presents a comparative analysis against alternative technologies such as Surface Relief Gratings (SRG) and Volume Holographic Gratings (VHG), highlighting their advantages in terms of scalability for mass production, cost efficiency, and optical performance. In addition, the presentation introduces Goertek’s investments and recent development progress in these technology areas.

液晶偏振体全息器件推动XR近眼显示技术突破

本次报告围绕偏振体光栅（Polarization Volume Grating，PVG）在 AR 光波导中的应用、Pancharatnam–Berry 相位透镜（Pancharatnam–Berry Phase Lens，PBL）在 VR 系统中的应用，以及偏振体全息光学器件（Polarization Volume Hologram，PVH）在 XR 近眼显示中的应用展开。报告系统介绍了上述光学器件的基本工作原理与制备方法，并与表面浮雕光栅（SRG）、体全息光栅（VHG）等同类技术进行了对比分析，突出其在易于规模化量产、成本控制及光学性能方面的优势。同时，报告还介绍了歌尔在相关技术方向上的研发投入与最新开发进展。
