Abstract
Magneto-optical displays offer numerous advantages in a multitude of applications, most notably large format signage applications. New designs and architectures such as the use of optical fluids, segmented magneto-optical element densities, frontplane lenses and color filters significantly expand the utility of these displays.
Claims23
A magneto-optical display comprising:
- a plurality of magneto-optical display elements;
- a cavity configured to house the plurality of magneto-optical display elements and permit rotation of the plurality of magneto-optical display elements;
- and
- an optical carrier fluid disposed within the cavity, wherein the plurality of magneto-optical display elements are placed in the optical carrier fluid;
- wherein the plurality of magneto-optical display elements comprise:
- a magnetic component;
- two colored surfaces that are configured to be rotated into a first and second viewable state;
- a top portion configured to have a density that is less than the optical carrier fluid, such that the top portion is buoyant;
- and
- a bottom portion that has a density greater than the density of the optical carrier fluid, such that the bottom portion is non-buoyant.
7 more elements
A magneto-optical display comprising:
- a plurality of reflective bi-stable magneto-optical display elements configured to change from a first viewable color to a second viewable color, the plurality of magneto-optical display elements defining at least a portion of one or more display portions that changes color;
- one or more display portions that do not change color or that include a shadow;
- and
- a front panel including one or more optical elements configured to redirect light from the one or more display portions that do not change colors or include a shadow to the one or more display portions that do change color.
1 more element
A magneto-optical display comprising:
- a plurality of reflective bi-stable magneto-optical display elements configured to change from a first viewable color to a second viewable color;
- a frontplane disposed in front of the plurality of magneto-optical display elements;
- and
- one or more light sources placed at one or more edges of the frontplane, wherein the frontplane is configured to direct light generated by the one or more light sources towards the plurality of magneto-optical display elements.
1 more element
A magneto-optical display comprising:
- a plurality of reflective bi-stable magneto-optical display elements configured to change from a first viewable color to a second viewable color, wherein the first color is a color configured to at least partially reflect light and the second color is a color configured to at least partially absorb light;
- a frontplane disposed in front of the plurality of magneto-optical display elements;
- and
- one or more color filters placed between the plurality of magneto-optical display elements and an observer of the display, wherein the one more color filters are of a different color than the first and second colors.
1 more element
A magneto-optical display comprising:
- a plurality of reflective bi-stable magneto-optical display elements configured to change from a first viewable color to a second viewable color;
- a frontplane disposed in front of the plurality of magneto-optical display elements;
- and
- one or more graphics placed between the plurality of magneto-optical display elements and an observer of the display, wherein changing from the first viewable color to the second viewable color causes the one or more graphics to change from a third viewable color to a fourth viewable color.
1 more element
A magneto-optical display comprising:
- a plurality of magneto-optical display elements configured as one or more pixels;
- wherein the one or more pixels are configured in a full Red, Green and Blue (RGB) display;
- and
- wherein the one or more pixels are configured to be selectively activated when subjected to a magnetic field such that the activated pixels generate a plurality of color combinations viewable in the magneto-optical display.
