Samsung Metasurface 2D-3D Display Enables Seamless Switching and Wider Viewing Angles
Samsung Electronics and POSTECH have published research in Nature on a switchable 2D-3D display using a metasurface lenticular lens.
The system uses an ultra thin metalens made of nanoscale structures to switch between 2D and 3D modes through voltage control. It is the first demonstration of a single device that can transition between high resolution 2D viewing and stereoscopic 3D display.
For 2D use, the lens behaves like a concave surface, allowing light to pass straight through for a clear flat image. For 3D, it switches to a convex mode, enhancing depth and enabling multi view perception without glasses.
The design also improves physical constraints seen in earlier light field displays. It achieves a thickness of 1.2 mm and expands the viewing angle to up to 100 degrees, compared to about 15 degrees in conventional systems.
The team also built a 50 × 50 mm prototype and tested it on OLED panels, showing potential for use in smartphones, tablets and other devices.
