Researchers of King Abdullah University of Science and Technology (KAUST) have been working on improve efficiency of red Micro LEDs and they recently announced the achievement of manufacturing stable red Micro LED based on InGaN. (Image: KAUST) A major challenge facing the development of Micro LEDs is to integrate red, green and blue light into a single LED chip. Current RGB LEDs are made by combining two kinds of materials with InGaP red LEDs and InGaN blue and green LEDs. "Creating RGB displays requires the mass transfer...
