P‐83: Polarized Emission from Perovskite Nanocrystals Encapsulated in Stretched Porous Films for Liquid Crystal Displays

Abstract

The Lead halide perovskite nanoparticles are a promising color conversion material for display application. The polarized emission from perovskite color enhancement films can boost LCD efficiency. In this article, we propose a method to induce the polarized emission from isotropic perovskite nano‐cubes, using a stretched porous polymer film. Optical simulation is performed to optimize the system design. The polarized perovskite color enhancement film can bring the optical efficiency improvement of 16.8% is expected for LCDs. Furthermore, the porous film offers good stabilization for the perovskite nanoparticles making it feasible for reliable device application.
