DISPLAY METHOD, FILM AND DISPLAY DEVICE USING MAGNETIC PARTICLES

摘要

A display device and a display method using magnetic particles are disclosed. The display method includes: applying a first magnetic field to a plurality of particles in a state where the plurality of particles having a magnetic property and a certain color are dispersed in a solvent so that the plurality of particles are aligned in a direction parallel to a direction of the first magnetic field, and thus a plurality of particle chains are formed; and applying a second magnetic field to at least a part of the formed plurality of particle chains so that at least a part of the plurality of particle chains moves in a direction close to a display surface in an area to which the second magnetic field is applied, and thus the certain color is displayed on the display surface.
