A Few Key Technologies of Quantum Dot Light-Emitting Diodes for Display

In recent years, quantum dots (QDs) have been widely studied because of their precisely tunable, narrow, and strong emission. Different kinds of light-emitting diodes (LEDs) have been fabricated by QDs, and it is desirable to utilize QD-LEDs to form the next-generation display. Here, we review a few key technologies in the area of QD-LED displays, including the compositions and the structures of the QDs, the methods of forming QD layers, and the architectures, crosstalk, and encapsulations of the QD-LEDs.
