Materials Design Strategies for Flexible and Stretchable Quantum Dot Light-Emitting Diodes

Flexible and stretchable displays are essential components of next-generation electronic systems, serving as both signal outputs and inputs. While the excellent optical properties of quantum dots (QDs) have garnered significant interest for advanced display technologies, fabricating flexible and stretchable QD-based displays remains challenging due to the limited mechanical properties of QDs, which are insufficient to withstand various deformations. In this presentation, I will discuss materials design strategies for developing flexible and stretchable quantum dot light-emitting diodes (QLEDs). First, I will explore structurally stretchable QLEDs, focusing on device architectures such as ultrathin designs that enable mechanical flexibility. Next, I will examine methods to enhance the performance of QLEDs for integration into stretchable and wearable systems. Finally, I will present materials design approaches aimed at creating intrinsically stretchable QLEDs, ensuring durability and functionality under extensive mechanical strain. These strategies aim to overcome the current limitations in the mechanical robustness of QLEDs, paving the way for the next generation of flexible and stretchable display technologies based on quantum dots.
