AI Summary

Researchers have fabricated a three‑dimensional achromatic metalens using a printable grayscale electron‑beam‑lithography nano‑template and integrated it with an OLED display to produce a sharp, full‑color image directly on the retinal plane. The demonstration shows that the metalens can support near‑eye display imaging with bright colors, addressing two major challenges for augmented‑ and virtual‑reality glasses.
