Diagrammatic drawing of meta-II NED. a The 3D AR effect of the meta-II NED with the major components of the metalens array and the micro-display. The light from the micro-display enters the human eye through the metalens array and a beam splitter’s reflection, while the ambient light can also be seen through the beam splitter. The virtual 3D images (number “3” and letter “D”) are reconstructed to coincide with the chess pieces (“Rook” and “Pawn”), respectively. b The photograph of the assembled meta-II micro-display panel. The micro-display and the metalens array are well aligned and assembled on both sides of the 3D-printed holder
