Patent number: 7848006Abstract: An electrophoretic medium has walls defining a microcavity containing an internal phase. This internal phase comprises electrophoretic particles suspended in a suspending fluid and capable of moving therethrough upon application of an electric field to the electrophoretic medium. The average height of the microcavity differs by not more than about 5 ?m from the saturated particle thickness of the electrophoretic particle divided by the volume fraction of the electrophoretic particles in the internal phase.Type: GrantFiled: May 15, 2008Date of Patent: December 7, 2010Assignee: E Ink CorporationInventors: Russell J.

Patent number: 7848007Abstract: A two-phase electrophoretic medium comprises a continuous phase and a discontinuous phase. The discontinuous phase comprises a plurality of droplets, each of which comprises a suspending fluid and at least one particle disposed within the suspending fluid and capable of moving through the fluid upon application of an electric field to the electrophoretic medium. The continuous phase surrounds and encapsulates the discontinuous phase. To reduce the humidity sensitivity of the medium, a non-ionizable or crystalline polymer may be used as the continuous phase.Type: GrantFiled: July 3, 2008Date of Patent: December 7, 2010Assignee: E Ink CorporationInventors: Richard J.

Publication number: 20100207073Abstract: Disclosed herein are novel electrophoretic displays and materials useful in fabricating such displays. In particular, novel encapsulated displays are disclosed. Particles encapsulated therein are dispersed within a suspending, or electrophoretic, fluid. This fluid may be a mixture of two or more fluids or may be a single fluid. The displays may further comprise particles dispersed in a suspending fluid, wherein the particles contain a liquid. In either case, the suspending fluid may have a density or refractive index substantially matched to that of the particles dispersed therein. Finally, also disclosed herein are electro-osmotic displays. These displays comprise at least one capsule containing either a cellulosic or gel-like internal phase and a liquid phase, or containing two or more immiscible fluids. Application of electric fields to any of the electrophoretic displays described herein affects an optical property of the display.Type: ApplicationFiled: April 5, 2010Publication date: August 19, 2010Applicant: E INK CORPORATIONInventors: Barrett Comiskey, Joseph M.

Patent number: 7728811Abstract: A process for creating an electronically addressable display includes multiple printing operations, similar to a multi-color process in conventional screen printing. In some of the process steps, electrically non-active inks are printed onto areas of the receiving substrate, and in other steps, electrically active inks are printed onto different areas of the substrate. The printed display can be used in a variety of applications. This display can be used as an indicator by changing state of the display after a certain time has elapsed, or when a certain pressure, thermal, radiative, moisture, acoustic, inclination, pH, or other threshold is passed. In one embodiment, the display is incorporated into a battery indicator. A sticker display is described. The sticker is adhesive backed and may then be applied to a surface to create a functional information display unit. This invention also features a display that is both powered and controlled using radio frequencies.Type: GrantFiled: September 3, 2004Date of Patent: June 1, 2010Assignee: E Ink CorporationInventors: Jonathan D.

Publication number: 20090174651Abstract: An electronic display comprises an electro-optic material (preferably an electrophoretic medium) having a plurality of pixels, and separate first, second and third sets of addressing means for addressing these pixels. Each of the pixels is associated with one addressing means in each of the three sets, such that addressing of any specific pixel requires application of signals within predetermined ranges to each of the three addressing means associated with the specific pixel being addressed. The display may be in the form of a multi-page electronic book.Type: ApplicationFiled: March 18, 2009Publication date: July 9, 2009Applicant: E INK CORPORATIONInventors: Joseph M.
