DISPLAY METHOD, FILM AND DISPLAY DEVICE USING MAGNETIC PARTICLES
First Claim
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.

Abstract
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.

17. A display device using magnetic particles, comprising:
-
a plurality of particles having a magnetic property and a certain color; a solvent in which the plurality of particles are dispersed; a first magnetic field application unit that applies a first magnetic field to the particles and the solvent; and a second magnetic field application unit that applies a second magnetic field to the particles and the solvent, wherein the first magnetic field application unit applies the first magnetic field to the plurality of particles in a state where the plurality of particles are dispersed in the solvent so that the plurality of particles are aligned in a direction parallel to a direction of the first magnetic field and the plurality of particle chains are formed, and the second magnetic field application unit applies 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.

36. A film using magnetic particles, comprising:
-
a plurality of particles having a magnetic property and a certain color; and a solvent in which the plurality of particles are dispersed, wherein, if a first magnetic field is applied to the plurality of particles in a state where the plurality of particles are dispersed in the solvent, the plurality of particles are aligned in a direction parallel to a direction of the first magnetic field so that the plurality of particle chains are formed, and if a second magnetic field is applied to at least a part of the formed plurality of particle chains, 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.
