Abstract：

We　propose　here　a　novel　multi-layered　waveguide　liquid　crystal　(LC)　smart　window　with　full　color　rendering　based　on　a　polymer-network　liquid　crystal　system.　The　inserted　position　of　three-primary-color　LED　light　bars　is　specially　designed,　which　is　parallel　to　the　LC　alignment　to　obtain　a　higher　difference　between　transparent　and　scattering　states.　The　optimal　matching　of　polymer-network　LC　system　is　experimentally　achieved　by　comparing　several　groups　of　LC　and　reactive　mesogen　materials.　The　prepared　smart　window　is　measured　and　analyzed　in　detail　including　optical/chromatic　test,　morphology　characterization,　and　actual　application　effect.　The　proposed　architecture　opens　up　new　prospects　of　flexible　color　switchable　ability　and　synchronized　full-color　display　for　smart　windows　without　limitations　of　slow　LC　response　time　and　complicated　field　sequential　driving　scheme.　©　2019　Optical　Society　of　America　under　the　terms　of　the　OSA　Open　Access　Publishing　Agreement
