Paper Abstract

Light-emitting displays with colloidal quantum-dot (QD) have recently received considerable attention due to advantages of QD property such as high quantum yields, extremely narrow emission, spectral tunability, and a higher stability than other existing luminophores. However, the difficulty of patterning red, green, and blue (RGB) pixels of three individual QDs with controlled interfaces has prevented from developing a full-color QD display with acceptable quantum efficiency. In this talk, the issues of QD EL and successful embodiment of full-color QD display by the solvent-free transfer printing of QD pattern will be presented. Modulated QD assemblies exhibit the excellent morphology, wellordered QD structure, and clearly defined interfaces, which result in significant enhancements in the charge transport/balance in the QD layer. A large-area full-color QD displays on a glass substrate, and even on a flexible substrate can be realized in this manner with the control of nano-interfaces and carrier behaviors.
