Abstract
Composite magneto-optical elements with unique shapes and architectures comprising a magnetic component and a colored component. These magneto-optical elements can also be manufactured by a small variety of low-cost processes resulting in their use in a variety of applications including low-cost, large-format, reflective display devices.
Claims25
A composite magnetic display element comprising:
- a body material portion;
- a magnetic material portion;
- a first optical portion having a first color;
- a second optical portion having a second color, wherein the first and second optical portions bisect along a plane of color separation;
- and
- wherein the magnetic display element is magnetized such that a North-South dipole of the display element is parallel to the plane of color separation and perpendicular to an axis of rotation of the display element.
A composite magnetic display element comprising:
- a body material portion;
- a magnetic material portion;
- a first optical portion that is clear or transparent;
- a second optical portion having a first color;
- a third optical portion having a second color, wherein the second and third optical portions bisect along a plane of color separation;
- and
- wherein the magnetic display element is magnetized such that a North-South dipole of the display element is parallel to the plane of color separation and perpendicular to an axis of rotation of the display element.
A composite magnetic display element comprising:
- a body material portion;
- a magnetic material portion;
- a first optical portion having a first color and a second color, wherein the first and second colors form a first color plane;
- a second optical portion having a third color and a fourth color, wherein the third and fourth colors form a second color plane;
- and
- wherein the first and second color planes are perpendicular to one another.
A method of manufacture of a composite magnetic display element comprising the steps of:
- obtaining a magnetic material portion;
- placing a first color portion onto a first side of the magnetic material portion;
- placing a second color portion onto a second side of the magnetic material portion that is opposite the first side, wherein the combination of the magnetic material portion and the first and second color portions comprises a laminate combination;
- and
- stamping the laminate combination to obtain the composite magnetic elements.
A method of manufacture of a composite magnetic display element comprising the steps of:
- obtaining a magnetic material;
- obtaining a body portion material, wherein the body portion material is one of a plastic or polymer, ceramic, glass, metal, alloy, or any combination thereof;
- combining the magnetic material and the body material into a composite element;
- extruding the composite element to form the magnetic display elements;
- and
- magnetizing the display elements and fixing the magnetic orientation of a North-South dipole of the display element.
