An electro-optic device comprising electrophoretic medium including a dispersion of a plurality of particles in a fluid configured to migrate within the fluid in a direction responsive to an applied electric field. The plurality of particles include a first type of particles having a first charge of a first charge polarity, a second type of particles having a second charge of a second charge polarity, and a third type of particles having a third charge of the second charge polarity. The first charge polarity is opposite to the second charge polarity, and the third type of particles are configured to migrate within the fluid in a direction responsive to an applied magnetic field gradient.

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.

Embodiments of the present invention are directed to systems and methods for writing on electronic paper (“e-paper”) and display platforms implemented with e-paper. In one aspect, a system for writing information to electronic paper includes a writing module and an erasing unit connected to the writing module. The erasing unit is configured to erase information stored in the electronic paper. The system also includes a writing unit connected to the writing module and is configured to write information to the electronic paper. Information is written to the electronic paper by orienting the writing module so that the electronic paper passes the erasing unit prior to passing the writing unit.

A recording layer is described that comprises a magnetizable material configured to store an image represented by magnetized regions of the magnetizable material. The magnetizable material may be brought into proximity with a magnetically responsive display layer, which may cause a change in an optical state of the display layer such that a facsimile of the image represented by the magnetized regions is produced within the display layer.
