  • Patent number: 11934593
    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.

  • Publication number: 20240061305
    Abstract: A system for simplified driving of electrophoretic media using a positive and a negative voltage source, where the voltage sources have different magnitudes, and a controller that cycles the top electrode between the two voltage sources and ground while coordinating driving at least two drive electrodes opposed to the top electrode. The resulting system can achieve roughly the same color states as compared to supplying each drive electrode with six independent drive levels and ground. Thus, the system simplifies the required electronics with only marginal loss in color gamut. The system is particularly useful for addressing an electrophoretic medium including four sets of different particles, e.g., wherein three of the particles are colored and subtractive and one of the particles is light-scattering.

  • Publication number: 20220334448
    Abstract: 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.
