Electrophoretic display modules including various types of backplane and edge seals for protecting electro-optic displays against environmental contaminants are described. In particular, the disclosed module designs allow for very narrow edge seals, i.e., less than 1 mm in thickness. In one type of seal, the electro-optic layer is sandwiched between a backplane and a protective sheet and a sealing material extends between the backplane and the protective sheet. In some instances, the protective sheet includes several layers of transparent materials to provide physical protection and reduce the ingress of water.

Electrophoretic display with low profile edge seal

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.

Sub-threshold addressing and erasing in a magneto-electrophoretic writing medium

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.

Electro-optic media and writable display incorporating the same

A stylus for interacting with a magnetic writing medium, such as a magneto-electrophoretic media containing magnetic particles that can be switched electrically in the same way as a conventional electrophoretic display: e.g., between white and black states with the capability of also attaining stable intermediate states of gray. The stylus includes a magnetic sphere and a metal cylinder aligned in the tip.
