KERI Nanophotonic 3D Printing equipment (IMAGE) National Research Council of Science & Technology Caption Companies across the world are competing fiercely to provide high-resolution displays to electronic devices such as TVs and smartphones. In particular, the virtual reality, a keyword of the 4th industrial revolution, requires a much higher resolution to improve the picture quality. A Korean research team developed a technology to produce a 'nano display' with a phenomenal resolution based on the 3D printing technique and posted the result of the study on a SCI journal, garnering much global attention.
