Electronic Ink and Electronic Paper


Books with printed pages are unique in that they embody the simultaneous, high-resolution display of hundreds of pages of information. The representation of information on a large number of physical pages, which may be physically turned and written on, constitutes a highly preferred means of information interaction. An obvious disadvantage of the printed page, however, is its immutability once typeset. We are currently developing electronically addressable paper-page displays that use real paper substrates. This effort includes the development of novel, electronically addressable contrast media, microencapsulation chemistry, and desktop printing technologies to print functional circuits, logic, display elements, and actuators on paper or paper-like substrates.
