Display Resolution Increases by 3D-Printing Quantum Dot Nanopixels

A display technology developed at the Korea Electrotechnology Research Institute (KERI) produces 3D pixels with nanoscale dimensions by 3D-printing quantum dots (QDs) embedded in polymer nanowires. The technology — called “nanophotonic 3D printing” by the research team — could be used to achieve superhigh-resolution displays in TVs, smartphones, virtual reality headsets, and other devices. The more pixels on a display screen and the more densely the pixels are integrated, the higher the resolution. To increase the number of pixels that can appear on a screen, the traditional approach has been to reduce the pixel size. Achieving a higher definition through a smaller pixel size has become a key to leading in...
