Nanotubes used to create 3D holographic displays

Up until today, when LCD was used to create 3D displays, the results were poor either in depth or resolution. Ferroelectric LCoS microdisplays have been used to project simple 3D images (see image below), but the quality and viewing angle are limited.

Researchers have created a new liquid-crystal 'pixel' using carbon nanotubes as conducting element within the pixel. This can be used to create 3D electrode structures in optically anisotropic media such as liquid crystals, making novel new micro-optical components possible. They say that this technology can be used to create near-perfect hologram.
