Abstract: Reflective, low-cost display pixels and displays incorporating magneto-optical elements wherein an externally applied magnetic field is perpendicular to an axis of rotation of the magneto-optical elements and parallel to a viewing plane of a display made from these elements. The display elements have a restricted rotation about their long axis which can be actuated by an external magnetic field to produce a bistable, electronically writable image. In addition, architectural modifications to this arrangement can be made such that the power required to write the image to such a display is decreased, overall display efficiency is increased and cross-talk between pixels is nearly eliminated.

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.

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.

Abstract: A write head for use in a bistable, magnetic optical display comprising one or more conducting coils configured to generate a magnetic field that is substantially perpendicular to the axis of rotation of one or more magneto optical elements of the optical display and parallel to a display viewing plane of the one or more magnetic display elements of the magnetic optical display such that an electrical pulse of less then 150 milliseconds is sufficient to create a magnetic field that alters the bistable state of the magneto optical display such that the display will stay in this new state without the need for ongoing electrical current being applied to the write head.
