Abstract

In backlighting systems for liquid crystal displays, conventional red, green, and blue (RGB) light sources that lack polarization properties can result in a significant optical loss of up to 50% when passing through a polarizer. To address this inefficiency and optimize energy utilization, this study presents a high-performance device designed for RGB polarized emissions.

The device employs an array of semipolar blue µLEDs with inherent polarization capabilities, coupled with mechanically stretched films of green-emitting CsPbBr₃ nanorods and red-emitting CsPbI₃-Cs4PbI6 hybrid nanocrystals. The CsPbBr₃ nanorods in the polymer film offer intrinsic polarization emission, while the aligned-wire structures formed by the stable CsPbI₃-Cs₄PbI₆ hybrid nanocrystals contribute to substantial anisotropic emissions, due to their high dielectric constant.

The resulting device achieved RGB polarization degrees of 0.26, 0.48, and 0.38, respectively, and exhibited a broad color gamut, reaching 137.2% of the NTSC standard and 102.5% of the Rec. 2020 standard. When compared to a device utilizing c-plane LEDs for excitation, the current approach increased the intensity of light transmitted through the polarizer by 73.6%. This novel fabrication approach for polarized devices containing RGB components holds considerable promise for advancing next-generation display technologies.
