WRITEABLE ELECTROPHORETIC DISPLAY AND PEN CONFIGURED TO WRITE ON ELECTROPHORETIC DISPLAY WITH DISAPPEARING INK AND ELECTROMAGNETIC SENSING

摘要

A writeable system that includes pen-like visual feedback and digitization of the stylus strokes. The system incorporates disappearing ink into a stylus (i.e., pen) that is configured to interact with a digitizing layer of an electrophoretic display. The electrophoretic display includes a clear protective sheet that can be written on with the disappearing ink. As the stylus is moved over the display, an ink trail is left on the display, however, after a short amount of time, the ink fades as the writing in replaced with an updated image corresponding to the stylus motion.
