The researchers demonstrated that an optically asymmetric structure can be exploited to guide light with directionality. A Lucius prism array has two distinct properties: the directional transmission of light and the disproportionation of light intensity. These allow the illumination of objects only in desired directions. Set up as an array, the Lucius prism can function as an autostereoscopic three-dimensional display.
Commercial production of the film can begin almost immediately, although it would take some time in order to be optimized for use in TVs, the researchers added.
"If consumer electronic manufacturers such as Samsung Electronics Co. and LG Electronics Inc. wanted to use the technology, they should be able to make 3D products that do not need glasses within a year," commented Char Kook-heon, who led the research and is a professor at SNU's school of chemical and biological engineering.
The discovery was published in the latest online issue of Nature Communications.
