Many of the electronic devices we use in our everyday life employ liquid crystals in their optical displays. Electric field induced orientational transitions of elongated liquid crystal molecules are at the heart of LC technologies. Changing the applied voltage controls the orientation of liquid crystals and their properties such as color. Scientists now report an experimental observation of the electro-optical effect that is completely opposite to the conventional guest-host effect: ferroelectric nanoparticles being switched by an external field mediate the switching of liquid crystals.
