To enhance the accessibility of augmented reality (AR) eyewear and virtual reality (VR) headsets, it is crucial to offer a cost-effective and high-quality display solution. Liquid crystal (LC) technology has been extensively researched for this purpose, with Liquid-Crystal Polarization Holograms (LCPHs) standing out as a compact, lightweight solution with versatile optical capabilities essential for AR/VR systems. The fabrication of LCPHs utilizes polarization selectivity and self-assembly, enabling potential cost-effective streamlined production and advanced fabrication approaches. However, there are material requirements and technical challenges that need to be addressed together to achieve an immersive viewing experience with LCPHs. By exploring these opportunities and addressing the challenges, the integration of LCPHs holds the promise of revolutionizing AR/VR optics and providing an accessible, high-quality, and immersive viewing experience for various applications.
