MIT Researchers Demonstrate Resin Encapsulation Extends Quantum Dot LED Lifespan 5,000-Fold

A study led Quantum dots are nanoscale semiconductor particles that emit pure, saturated colors when electrically excited. They are already used in premium displays as color converters, but QD-LEDs, where quantum dots serve as the light-emitting layer rather than a conversion layer, have struggled with short operating lifetimes. The MIT team found that degradation occurs through a combination of moisture ingress, oxidation, and electric-field-driven ion migration that damages the quantum dot surface and surrounding transport layers.
