“…To solve the edge ingress problem, strategies have been developed to prevent direct contact between the air and the PeNC layer by attaching barrier films to the surface of the PeNC layer to suppress inward diffusion of air and moisture, or by introducing predesigned patterns in the UV layer to minimize H 2 O diffusion into the UV layer and to act as a guide to the film thickness.

Strategies to Extend the Lifetime of Perovskite Downconversion Films for Display Applications

Metal halide perovskite nanocrystals (PeNCs) have outstanding luminescent properties that are suitable for displays that have high color purity and high absorption coefficient; so they are evaluated for application as light emitters for organic light‐emitting diodes, light‐converters for downconversion displays, and future near‐eye augmented reality/virtual reality displays. However, PeNCs are chemically vulnerable to heat, light, and moisture, and these weaknesses must be overcome before devices that use PeNCs can be commercialized. This review examines strategies to overcome the low stability of PeNCs and thereby permit the fabrication of stable downconversion films, and summarizes downconversion‐type display applications and future prospects. First, methods to increase the chemical stability of PeNCs are examined. Second, methods to encapsulate PeNC downconversion films to increase their lifetime are reviewed. Third, methods to increase the long‐term compatibility of resin with PeNCs, and finally, how to secure stability using fillers added to the resin are summarized. Fourth, the method to manufacture downconversion films and the procedure to evaluate their reliability for commercialization is then described. Finally, the prospects of a downconversion system that exploits the properties of PeNCs and can be employed to fabricate fine pixels for high‐resolution displays and for near‐eye augmented reality/virtual reality devices are explored.
