Quasi-two-dimensional (quasi-2D) perovskites have emerged as a transformative platform for high-efficiency perovskite light-emitting diodes (PeLEDs), benefiting from their tunable quantum confinement, high photoluminescence yields (PLQYs), and self-assembled energy funneling mechanisms. This review systematically explores interfacial transfer engineering strategies that underpin advancements in device performance. By tailoring phase composition distributions, passivating defects via additive engineering, optimizing charge transport layers, researchers achieved external efficiencies (EQEs) exceeding 20% green red PeLEDs. However, challenges persist blue emission stability, efficiency roll-off at currents, long-term operational durability driven by spectral redshift, Auger recombination, ion migration. Emerging solutions include dual-cation/halogen alloying bandgap control, microcavity photon management, insulator–perovskite–insulator (IPI) architectures to suppress leakage currents. Future progress hinges on interdisciplinary efforts multifunctional material design, scalable fabrication, mechanistic studies of carrier–photon interactions. Through these innovations, quasi-2D PeLEDs hold promise next-generation displays solid-state lighting, offering cost-effective efficient alternative conventional technologies.
