Patent number: 11195481Abstract: 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: GrantFiled: September 27, 2019Date of Patent: December 7, 2021Assignee: E Ink CorporationInventors: 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: 20210355332Abstract: Improved formulations of electrophoretic media that can be incorporated into displays, front plane laminates, inverted front plane laminates, or color changing films. The formulations include a non-polar fluid, a plurality of first charged particles, and charge control agents (CCA) including a quaternary amine and an unsaturated polymeric tail comprising monomers of at least 10 carbon atoms in length. The formulations show improved switching speeds, as well as a larger dynamic range at low temperatures (i.e., below about 0° C.), where compared to state-of-the-art electrophoretic media.Type: ApplicationFiled: July 21, 2021Publication date: November 18, 2021Inventors: Ziyan WU, Jason D. FEICK, James H. ABORN, John LOCK, Kosta LADAVAC, Erik DUNKERLEY, Hui DU, Olga Vladimirovna BARYKINA-TASSA

Patent number: 11084935Abstract: Quinacridone pigments that are surface-functionalized with glycidyl methacrylate, maleic anhydride, or 4-methacryloxyethyl trimellitic anhydride to create a functionalized pigment. The functional groups are then activated to bond hydrophobic polymers, thereby coating the pigment with the hydrophobic polymers. The quinacridone pigments can be used for a variety of applications. They are well-suited for use in electro-optic materials, such as electrophoretic media for use in electrophoretic displays.Type: GrantFiled: April 13, 2020Date of Patent: August 10, 2021Assignee: E Ink CorporationInventors: Ziyan Wu, Jason D.

Patent number: 9158174Abstract: In electrophoretic media, it is advantageous to use pigment particles having a polymer chemically bonded to, or cross-linked around, the pigment particles, the polymer comprising repeating units derived from a fluorinated acrylate or fluorinated methacrylate monomer. The polymer desirably has a branched chain structure with side chains extending from a main chain. Desirably, the fluorinated acrylate or fluorinated methacrylate monomer comprises from 1 to 5 mole percent of the polymer.Type: GrantFiled: November 11, 2013Date of Patent: October 13, 2015Assignee: E Ink CorporationInventors: Michael D.
