MicroLED—sometimes written as μLED—is a flat screen technology based on arrays of microscopic LEDs, made of InGaN(Indium Gallium Nitride), that form the individual picture elements (pixels). Like OLEDs and plasma screens, µLED pixels are self-illuminating, dimmable, and can be switched off completely, so they don’t require backlighting as in LCDs (liquid crystal displays). In general,…
