Abstract: Quantum dot (QD) light-emiting diodes (QLEDs) are considered one of the most promising devices for future full-color displays due to their high color purity with narrow emission bandwidth, high brightness, and solution processability. However, fundamental mechanisms, such as charge injection into QDs, exciton recombination, and operational stability, should be understood to realize the QLED displays. In this presentation, a recent research progress in my group, including the mechanisms of charge carrier and exciton dynamics in QLEDs and the device design and fabrication processes to achieve high performance QLEDs, are discussed.
