There is one exciting Korean scientific idea that has produced a machine showing a three-dimensional holographic display, according to Engadget.

The team that is making the machine is comprised of a dozen companies. Hence, the Electronics and Telecommunications Research Institute (ETRI) has converted fantasy into reality.

While there are a number of techniques and technologies that create holograms, none of them appear to be functioning as well as ETRI. There are 16 other companies, who are said to have made this "tabletop holographic display." It is the first of its kind, and permits its user to see an image in complete color at all angles around it, according to KBS World Radio. This technology can create a hologram that is just about three inches.

It diffracts light waves, which is a far cry from the 3D holograms and images that have been exhibited in films and television, according to Business Korea.

The 2D image hanging in the air has been made by the other technologies. This is not like the "real 3D imaging" leading to an image shown at diverse angles.
