Zusammenfassung:A changeable display element is edgewise mounted on an insulating board and carries to rotate through about 180 DEG to show one color face or the other to a viewer. The board provides a similarly colored face for each face to form a pixel. The element carries a permanent magnet and is driven by a switchable magnetic field provided from the board. Soft iron pads on the board cooperate with the magnet on each position to retain the element against incidental displacement between application of the field. The board may support arrays of such elements.
