ABSTRACT:
A sheet material for use in a gyricon display in which a rotatable element, which has a portion which is capable of being permanently magnetized may be oriented to experience an attractive force between itself and a soft magnetic material pad. The attractive force between the element and the pad serve to latch the element in place and prevent unwanted display changes from taking place. The element may be constructed to be either cylindrically or spherically shaped. The element and the soft magnetic material pads may be arranged to provide multiple latching states as desired.
