The development of glasses-free 3D multiview displays has opened up new avenues for
experiencing 3D displays. Multiview technologies have the advantages
of visual discomfort alleviation, smooth motion parallax, full-color
display, and broad depth of focus. However, their intended uses are
impeded due to the versatility of designing ultrathin display systems
freely by using metasurface technology. This paper presents a
technique for creating an ultrathin ring-shaped metasurface for a
multiview display system with a thickness of 2 µm. The proposed
multiview 3D display system generates eight views. Numerical
simulations are used to confirm the efficacy of the suggested
strategy, and the results demonstrate the attainment of a high-quality
multiview 3D display. The proposed work demonstrates the potential
applications of the metasurface in multiview display systems for
electromagnetic wave manipulation in future 3D TVs, imaging,
integrated optics, and next-generation compact displays.
