Lead halide perovskite quantum dots (LHP QDs) exhibit great potential in the backlighting display of light-emitting diode applications. Light-emitting backlighting with high brightness, low cost, and wide color gamut can be achieved based on LHP QDs, which have the advantages of high luminescence performance, tunable emission, and facile synthesis. However, some drawbacks, including instability and large-scale synthesis, that restrict the practical application of LHP QDs remain. This Review focuses on solutions to these obstacles. The gap between fundamental knowledge to backlighting applications must be narrowed. The strategies for stability improvements and scalable synthesis are summarized and clarified. This Review provides inspiration for the optimization of LHP QDs, promotes their application in wide color gamut backlighting, and contributes to current and future display solutions.
