63‐2: Full degree‐of‐freedom liquid crystal holographic optics for AR/VR displays

Liquid crystal polarization holograms (LCPHs) based on photo‐alignment and self‐assembled liquid crystal are attractive for the attributes like micrometer ultra‐thinness, high efficiency and dynamic tunability. Previous fabrication methods are limited in the degree‐of‐freedom (DoF) in both photoalignment process and liquid crystal deposition. This work presents an full‐DoF LCPH by freeform exposure and inkjet printing, which is exemplified by building a full‐color retinal scanning display without color crosstalk.
