Korean researchers envision 3-D on OLED displays for smartphones and other gadgets

… Now a team of researchers in South Korea is developing an approach to autostereoscopic 3-D using tiny prisms that would enable viewers to see three-dimensional images without glasses on organic light-emitting-diode (OLED) screens. Because OLEDs do not need to be backlit—they get their lighting from organic compounds that emit light in response to electric current—they can be thinner, lighter and more flexible than LCDs. The innovation is detailed in a paper published in the August 30 issue of Nature Communications. (Scientific American is part of Nature Publishing Group.)  …

Arrays of Lucius microprisms for directional allocation of light and autostereoscopic three-dimensional displays

Abstract

Directional and asymmetric properties are attractive features in nature that have proven useful for directional wetting, directional flow of liquids and artificial dry adhesion. Here we demonstrate that an optically asymmetric structure can be exploited to guide light with directionality. The Lucius prism array presented here 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.
