Abstract

Metal halide perovskites could form the basis of future display technology due to their powerful optical properties. However, the commercialization of electroluminescent perovskites has been hindered by key challenges, including limited operational lifetime and instability in blue emission. Here we highlight the potential of perovskites in colour conversion displays. We examine the particular advantages of perovskite materials as colour conversion layers: narrow emission spectrum, high absorption coefficients, high-brightness operation, photon recycling and ease of manufacturing. We provide a framework for the development of RoHS (Restriction of Hazardous Substances)-compliant and colour-filter-free perovskite-based colour conversion displays and offer guidelines for commercialization. We also explore the potential of using perovskite colour conversion layers to create advanced augmented reality and virtual reality technologies.
