According to the patent application of the South Korean giant Samsung, the company has invented a device that projects a high-quality three-dimensional image into the surrounding space, which can be seen from any side..
The document says that the display uses a completely new type of spatial light modulator that removes the limitations of the viewing angle and provides high resolution hologram. According to patent description, the effect is achieved by several sets of flat microlens gratings that focus the light beams emitted from the display in the center, creating a 3D image projection in the air directly above the device.
Most of the existing holograms require a certain angle of view, such as still images on bank cards, and more advanced technologies that use laser projection are still very massive and cannot be placed in a portable device..
Samsung has previously reported on the development of related 3D holograms, but did not elaborate on the details. However, despite the data given in the description, some technical experts name statements companies with promises based only on laboratory tests.
Another tech giant, Intel, recently announced the development of a revolutionary type of transistor that consumes 30 times less power..
