Technology progress on quantum dot light-emitting diodes for next-generation displays

摘要: Quantum dot light-emitting diodes (QD-LEDs) are widely recognised as great alternatives to organic (OLEDs) due their enhanced performances. This focus article surveys the current progress on state-of-the-art QD-LED technology including material synthesis, device optimization and innovative fabrication processes. A discussion synthesis of core nanocrystals, shell layers surface-binding ligands is presented for high photoluminescence quantum yield (PLQY) dots (QDs) using heavy-metal free materials. The operational principles several types architectures also covered, recent evolution engineering technologies investigated. By exploring process pixel-patterning QD-LEDs an active-matrix backplane full-colour display applications, we anticipate further improvement in performance commercialisation next-generation displays.
