Colloidal Quantum Dot Electroluminescent Diodes for Display Applications: Progress and Challenges

Abstract

Colloidal quantum dots (QDs) have the advantages of easy tunable wavelength， narrow emission， high efficiency， and so on. Corresponding electroluminescent (EL) QD light-emitting diodes (QLED) have the advantag• es of solution treatment， simple and low cost manufacturing process， which is beneficial to realize the wide color gam • ut， high contrast， large area and flexible display. However， there are still challenges in device performance and pat• terning technology for QLED-based display applications. With the progress of material and device engineering， the research of QLED display has made further progress. This paper first introduces the development of QDs and QLED in display application， then indicates the challenge and research progress of QLED in display application.
