GoKawiilThree-dimensional display technology creates the illusion of depth by delivering slightly different images of a scene to each eye. This can be achieved using specialized glasses, but glasses-free 3D displays promise a more natural experience for entertainment, education and design. However, practical glasses-free displays, which are commonly based on optical devices called lenticular lenses, can generally only display high-quality images when viewed from a narrow range of angles. Furthermore, they have a limited resolution when displaying 2D images, which are still desirable for commercial displays. Writing in Nature, Moon et al.1 report a thin display that can switch between wide-angle 3D and high-resolution 2D operation, achieved using a nanostructured film called a metasurface.
