Inkjet-printed quantum dot light-emitting diodes: Development and challenges for display applications

Abstract

Quantum dot (QD) technology is rapidly advancing and draws much attention for display applications where accurate and vibrant color reproduction is highly required. Currently, significant research is being conducted in developing quantum dot light-emitting diode (QD-LED) as next-generation displays. QD-LEDs offer several advantages, including high color purity, wide color gamut, and lower manufacturing costs. Recent advancements in QD synthesis and device engineering have significantly improved the performance of QD-LEDs, but several challenges must be addressed for the successful commercialization. In this article, we provide an overview of QD-LED developments and key issues that are required to be solved for realizing practical inkjet-printed QD-LED displays.
