GRENOBLE, France \u2013 Sept. 16, 2025 \u2013 CEA-Leti and the Centre for Research on Heteroepitaxy and its Applications<\/a> (CRHEA) today announced R&D results that have cleared a path toward full-color microdisplays based on a single material system, a long-standing goal for augmented and virtual reality (AR\/VR) technologies.<\/p>\n The project, presented in a paper published in Nature Communications Materials<\/em><\/a>, developed a technique for growing high-quality InGaN-based quantum wells on sub-micron nanopyramids, enabling native emission of red, green, and blue (RGB) light from a single material system. Titled \u201cRegular Red-Green-Blue InGaN Quantum Wells With In Content Up To 40% Grown on InGaN Nanopyramids<\/a>\u201d, the paper will be presented at the MicroLED Connect Conference<\/a> on Sept. 24, in Eindhoven, the Netherlands.<\/p>\n Microdisplays for immersive devices require bright RGB sub-pixels smaller than 10 \u00d7 10 microns. According to the paper, \u201cthe use of III-nitride materials promises high efficiency micro-light emitting diodes (micro-LEDs) compared to their organic counterparts. However, for such a pixel size, the pick and place process is no longer suitable for combining blue and green micro-LEDs from III-nitrides and red micro-LEDs from phosphide materials on the same platform.\u201d Red-emitting phosphide micro-LEDs also suffer from efficiency losses at small sizes, while color conversion methods face challenges in deposition precision and stability.<\/p>\n","protected":false},"excerpt":{"rendered":" Interesting.
