Patent number: 6825829Abstract: 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: August 27, 1998Date of Patent: November 30, 2004Assignee: E Ink CorporationInventors: Jonathan D. Albert, Barrett Comiskey, Russell J. Wilcox

Publication number: 20040190114Abstract: A method for manufacturing a full color, reflective display includes the steps of depositing a first plurality of electrophoretic display elements in substantial registration with a first electrode and a second plurality of electrophoretic display elements in substantial registration with a second electrode. The electrophoretic display elements include a capsule containing a species of particles dispersed in a suspending fluid. The selective deposition of the display elements can be achieved by ink-jet printing methods, screen printing methods or other printing methods. In some embodiments the electrodes are printed onto the substrate before selective deposition of the display elements, while in other embodiments the substrate is provided having the electrodes already disposed on it. In still other embodiments, the sequence of printing of electrodes and electrophoretic display elements can be varied.Type: ApplicationFiled: April 2, 2004Publication date: September 30, 2004Applicant: E INKInventors: Joseph M.

Patent number: 6445489Abstract: Electrophoretic displays include a light-emitting layer, a photoconductive layer, and an electrophoretic layer. The light-emitting layer may be an organic, light-emitting material, or organic, light-emitting diode, which is addressable using a multiplex addressing drive scheme. The impedance of the photoconductive layer is lowered when struck by light from the light-emitting layer. As a result of the lowered impedance of the photoconductive layer, the electrophoretic layer, which itself cannot be multiplexed, is addressed at a lower, subthreshold voltage.Type: GrantFiled: March 18, 1999Date of Patent: September 3, 2002Assignee: E Ink CorporationInventors: Joseph M. Jacobson, Paul Drzaic, Barrett Comiskey, Russell J. Wilcox, Ian Morrison
