Patent number: 8077142Abstract: 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.Type: GrantFiled: September 24, 2007Date of Patent: December 13, 2011Assignee: Tred Displays CorporationInventors: Charles O.
