Switchable 2D-3D display through a metasurface lenticular lens

Three-dimensional (3D) displays provide immersive visuals by delivering depth cues, making them valuable for applications such as interactive media1,2. To enhance practicality, 2D–3D switchable displays offer the flexibility to toggle between high-resolution 2D and immersive 3D modes in a single device3,4. Here we propose a full-colour 2D–3D switchable light-field display powered by a metasurface lenticular lens (MLL). The MLL switches its focal behaviour on the basis of the polarization of incident light, serving as the core mechanism for 2D–3D mode transition. The MLL is designed with a high numerical aperture, enabling a notably wider field of view of 100° while maintaining an ultrathin profile of just 1.2 mm. A large-area MLL with an active area of 25 cm2 is fabricated and seamlessly integrated as a dual-dimension switchable optics device, demonstrating the scalability of the approach for wide-area display applications. The fabricated device, when simply mounted onto an organic light-emitting diode display panel, successfully demonstrates clear 2D and 3D images, along with the active switching functionality enabled by applied voltage. These results highlight a promising solution for next-generation display technologies in both consumer electronics and commercial applications.

The metasurface lenticular lens display technology has a numerical aperture of 0.65, enabling a wide field of view of 100 degrees while maintaining an ultrathin profile of 1.2 mm. This technology is powered by a metasurface lenticular lens that switches its focal behavior based on the polarization of incident light. The display has an active area of 25 cm2 and is fabricated using a large-area metasurface lenticular lens. The device is seamlessly integrated as a dual-dimension switchable optics device.

This technology directly affects consumers who use organic light-emitting diode display panels, as it enables the switching between 2D and 3D modes without the need for additional hardware. The cost of this technology is not yet publicly disclosed, but it is expected to be competitive with existing 3D display solutions. This could lead to a shift in the display market, with manufacturers incorporating this technology into their products. As a result, consumers can expect to see more affordable and versatile display options in the near future.

The development of this technology is part of a larger trend towards more immersive and interactive display solutions. Researchers have been working on metasurface-based display technologies for several years, with significant advancements in recent years. Insiders know that the key challenge in developing this technology was creating a metasurface lenticular lens that could efficiently switch between 2D and 3D modes. The solution involved designing a lens with a high numerical aperture and a specific polarization-dependent focal behavior.

The next step for this technology is to be integrated into commercial display products, with several companies already expressing interest in licensing the technology. A report on the commercial viability of this technology is expected to be released in the next quarter. The company behind this technology, which has not been publicly named, is expected to announce a partnership with a major display manufacturer by the end of the year. Surprisingly, the metasurface lenticular lens technology can also be used for augmented reality applications, which could be a major growth area for this technology in the future.
