APPARATUS FOR COLOR TUNABLE OPTICAL SHUTTER USING STRUCTURAL COLOR FILTER

摘要

The present invention relates to a shutter which expresses a variable color by using a liquid crystal and has an integrated structure with a polarizing plate and a structural color filter. According to the present invention, an apparatus for color tunable optical shutter using the structural color filter comprises: a liquid crystal which changes polarization characteristics according to an arrangement state; an electrode which varies the arrangement of the liquid crystal according to the application of voltage; and a structural color filter which is variably selected and expressed according to the polarization characteristic.;COPYRIGHT KIPO 2017
