Quantum dots vs. micro LEDs This isn’t the last step in QD display technology, though. While quantum-dot color filter screens are already coming to market, another advancement is waiting in the development labs: the QD version of the so-called “micro-LED” display. We’ve talked about the future of inorganic LEDs in displays before, but quantum dots can take that game to a whole new level. Up to now, we’ve only been talking about the photoemissive behaviors of QDs — how they can emit light after being excited by another light source. Quantum dots can also exhibit electro-emissive properties, in which they emit light directly in response to an electric field.
