  • Sub-threshold addressing and erasing in a magneto-electrophoretic writing medium
    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.
    Type: Grant
    Filed: February 21, 2023
    Date of Patent: March 19, 2024
    Assignee: E Ink Corporation

  • Stylus for addressing magnetically-actuated display medium
    Patent number: 11086417
    Abstract: 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.
