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. |

1. A display method using magnetic particles, comprising steps of:
(a) 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 a plurality of particle chains are formed; and (b) 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. |
