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 either an attractive force or a repelling force between itself and another magnetized element. The attractive force between the element and the pad serve to latch the element in place and prevent unwanted display changes from taking place while the repellant force serves to trap the element in place for the same reasons. The element may be constructed to be either cylindrically or spherically shaped. Further, the sheet material may also contain soft magnetic material pads which may be arranged to provide multiple latching states as desired.
