Pure red LEDs fulfill a primary goal

Making pure red LEDs from nitride crystals is a goal that has so far frustrated engineers. However, these LEDs are vital for building the next generation of energy-efficient micro-LED displays to follow OLED displays and for creating lighting with color tuning. Now, for the first time, a team of electrical engineers at KAUST has succeeded in making these LEDs, Phys.org reports. Electrical engineers can already make bright LEDs using varying materials to produce different colors. But to improve display technologies, engineers must integrate the three primary color LEDs, red, green and blue, onto one chip.
