Video displays that offer both 2-D and 3-D imaging without the use of eyewear are very popular to consumers worldwide. Viewers, however, usually have to watch from a distance of around one meter. This eradicates the application of this technology to mobile devices. But researchers at Seoul National University, South Korea, have simplified and shrunk the architecture of the technology to convert these displays for near-viewing capabilities.
Is this the end of the era of 3D glasses? MIT researchers have developed a 3D screen that allows people to watch 3D movies sans the glasses.
