Patent number: 9953588Abstract: A variable transmission medium comprises a fluid and a plurality of nanoparticles dispersed in the fluid, wherein addition of acid to the fluid causes the nanoparticles to flocculate and form aggregates of particles that scatter light. The nanoparticles may comprise at least one metal oxide, such as titanium dioxide, zinc oxide or zirconium dioxide. The fluid may have a dielectric constant less than about 10.Type: GrantFiled: March 25, 2015Date of Patent: April 24, 2018Assignee: E Ink CorporationInventors: Stephen J. Telfer, Richard J. Paolini, Jr., Stephen Bull, Joshua A. Ritchey, Kosta Ladavac, Lee Yezek, Craig A. Herb, Peter Carsten Bailey Widger

Patent number: 9921451Abstract: An electrophoretic medium comprises a fluid, a first, light scattering particle (typically white) and second, third and fourth particles having three subtractive primary colors (typically magenta, cyan and yellow); at least two of these colored particles being non-light scattering. The first and second particles bear polymer coatings such that the electric field required to separate an aggregate formed by the third and the fourth particles is greater than that required to separate an aggregate formed from any other two types of particles. Methods for driving the medium to produce white, black, magenta, cyan, yellow, red, green and blue colors are also described.Type: GrantFiled: September 10, 2015Date of Patent: March 20, 2018Assignee: E Ink CorporationInventors: Stephen J. Telfer, Stephen Bull, Jennifer M. Morrison, Luke M. Slominski, David Darrell Miller, Olga Vladimirovna Barykina-Tassa, Lee Yezek, Brandon MaCDonald, Kosta Ladavac, Craig A. Herb

Publication number: 20170287407Abstract: An electrophoretic display comprising a fluid including a first species of particles and a charge control agent disposed between first and second electrodes. When a first addressing impulse have an electrical polarity is applied to the medium, the first species of particles move in one direction relative to the electric field, but when a second addressing impulse, larger than the first addressing impulse but having the same electrical polarity, is applied to the medium, the first species of particles move in the opposed direction relative to the electric field.Type: ApplicationFiled: May 26, 2017Publication date: October 5, 2017Inventors: Stephen J. TELFER, Stephen BULL, Alain BOUCHARD, Craig A. HERB, Kosta LADAVAC, Ana L. LATTES, Jennifer M. MORRISON, Richard J. PAOLINI, JR., Michael Thomas REGAN, Luke M. SLOMINSKI, Lee YEZEK, Kenneth R.

Publication number: 20170253743Abstract: Polymer shells similar to those described in U.S. Pat. No. 6,822,782 can be formed on pigment particles by (a) physi-sorping a reagent comprising polymerizable groups on to the pigment particles by treating the particle with a reagent having a polymerizable or polymerization-initiating group, such that the reagent will not desorb from the particle surface when the particle is placed in a hydrocarbon medium; or (b) treating pigment particles bearing nucleophilic groups with a reagent having a polymerizable or polymerization-initiating group, and an electrophilic group, thus attaching the polymerizable or polymerization-initiating groups to the particle surface. The zeta potential of the pigment particles can be varied by a process similar to (b) but using a reagent which does not have a polymerizable or polymerization-initiating group.Type: ApplicationFiled: May 20, 2017Publication date: September 7, 2017Inventors: Lee Yezek, Andrew Drabek, Luke M. Slominski, Jennifer M. Morrison, Stephen J. Telfer, Brian Steinberg

Publication number: 20160187758Abstract: An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.Type: ApplicationFiled: March 3, 2016Publication date: June 30, 2016Inventors: Stephen J. Telfer, Richard J. Paolini, JR., Sunil Krishna Sainis, Randal M. Hill, Isaac W. Moran, Lee Yezek, Alain Bouchard, William Vetterling, George G.
