Optical display devices and methods of operating such devices are provided. The optical device includes a display component having a plurality of anisotropic multiphasic particles with at least two optically distinct phases. The plurality of anisotropic multiphasic particles is disposed in one or more regions of the display component that define an optic feature. Further, at least one of the phases of the anisotropic multiphasic particle comprises a material receptive to a force field, such as a magnetic material is receptive to an applied magnetic field. In this manner, the display component can reversibly exhibit a first optical state in the presence of the force field and thus is optionally switchable.
