Chemists have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field and that paves the way for display applications using instantaneous and contactless nature of magnetic manipulation - like a poster that customizes based on the people around it. Commercially available liquid crystals in electronic displays are composed of rod-like or plate-like molecules. When an electric field is applied, the molecules rotate and align themselves along the field direction, resulting in a rapid tuning of transmitted light. read more
