Abstract
A magneto-electrophoretic medium that can be globally and locally addressed and erased. The medium provides a writeable display with no perceivable lag and the ability to write and erase with only minimal power requirements. In particular, the magneto-electrophoretic medium can be erased by providing a subthreshold electric stimulus and supplementing a second non-electric stimulus that disturbs the written state and allows the magneto-electrophoretic particles to return to their original state.
