Spiral-in-Shrink Assembly of Microarchitected Circularly Polarized Luminescent Networks

High-fidelity three-dimensional displays require precise control over the polarization of light. Screens incorporating chiral emissive micropixels─which allow effective regulation of spin angular momentum─offer the potential for minimal-crosstalk, high-definition imaging. However, such highly asymmetric luminous, densely integrated microarrays have not yet been reported, owing to interfacial pinning effects and easy chiral structural degradation during miniaturization. Here, we present a spiral-in-shrink assembly strategy that couples evaporation-induced contraction with chiral self-organization in a nonequilibrium pathway. Geometry-confined shrinkage and chiral helically ordered microdomes act in concert to stabilize circularly polarized emission, yielding lateral features of 58 μm─corresponding to a significant improvement in miniaturization over reported dimensions. Large-area arrays comprising over 31,000 emissive units achieve 359 pixels per inch─and luminescence dissymmetry factors up to 1.25, enabling densely packed full-color photonic patterning. Moreover, spatially encoded handedness distributions underpin polarization-resolved mapping on aerial platforms for human–machine sensing. Our scalable route establishes a platform for cohesive chiroptical materials across advanced optical displays, polarization imaging, and intelligent sensing.
