Research Progress of Metasurface-Based VR/AR Display Technology
As the next-generation innovative technologies emerging after computers, smartphones, and the Internet, virtual reality (VR) and augmented reality (AR) are changing the way we perceive and communicate with the world. VR/AR head-mounted displays have flourished in the recent years, creating an increasingly urgent need for high-resolution and-brightness miniature displays and small-volume and lightweight near-eye display opto-systems. As new ultra-thin optical components with subwavelength nanostructures lined up on a two-dimensional plane, metasurfaces with powerful electromagnetic wave modulation capabilities beyond traditional optical devices are accelerating the development of VR and AR devices toward miniaturization and light weightedness. We first briefly introduce herein the basic principle of the VR/AR display technology and review its development history. We focus on the design principles, performance characteristics, and application methods of metasurfaces and metalenses in optical systems for VR/AR near-eye displays. We then introduce the role and the application effects of metasurfaces in micro-display devices. In addition, we present the micro- and nano-fabrication technologies related to metasurfaces and the large-area mass fabrication method. Finally, we provide a summary of the metasurface-based VR/AR display technology and an outlook on its development prospects.
