As the demand for information capacity and color quality continues to increase, color optical holography has garnered significant attention and is now widely applied in areas such as color displays, augmented reality (AR)/virtual reality (VR) and information encryption. However, most current color holography techniques are based on metasurfaces and similar systems, achieving color holography in soft matter, specifically those represented by liquid crystals, remains challenging. In this study, we propose a bi-chiral cholesteric liquid crystal (CLC) superstructure, which enables circular polarization multiplexed color holography through the liquid crystal photoalignment and Bragg reflection band modulation techniques. By employing washout and refill steps involving a surface-initiated polymerization process, alongside liquid crystal photopatterning technology, we achieve spin-decoupled geometric phase, enabling the independent phase modulation of left- and right-handed circularly polarized light. The geometric phase and the resultant holographic image are generated exclusively when the incident light’s polarization and wavelength precisely match those of the CLC. Through the independent control of Bragg reflection bands in left- and right-handed CLCs, multiple holographic images are successfully generated on the same diffraction plane, resulting in the tunable and multiplexed color holography. The proposed spin-decoupled color holography via bi-chiral liquid crystal superstructures holds great promise in advanced displays, optical encryption and multi-channel communication.
