A layered structure comprises a transreflective layer configured to transmit light in a transmissive polarization orientation and reflect light in a reflective polarization orientation, at least one guest host (GH) liquid crystal layer comprising liquid crystal molecules and dichroic dye molecules and controllable to operate in at least a vertical state and a planar state. The layered structure is configured to transmit linearly polarized light. In a first reflection mode, the layered structure is configured to reflect light corresponding to a first reflectivity rate. In a second reflection mode, the layered structure is configured to reflect light corresponding to a second reflectivity rate less than the first reflectivity rate.
