Abstract
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.
