  • Electronic inks and displays and image displaying methods
    Patent number: 8356752
    Abstract: An electronic ink containing charged particles includes a combination of resin particles, a pigment, and a charge director. The resin particles exhibit an average particle size less than 1.0 micron and contain a resin that exhibits a molecular weight of 500 to 20,000. The pigment is loaded on the resin particles. The charge director can physically associate with the resin particles. The charged particles may be negative or positive.

  • DUAL COLOR ELECTRONICALLY ADDRESSABLE INK
    Publication number: 20130016420
    Abstract: A dual color electronically addressable ink includes a positively charged ink and a negatively charged ink. The positively charged ink includes a non-polar carrier fluid, pigment-loaded basic resin particles having a first color, and an acceptor charge adjuvant. The negatively charged ink includes the non-polar carrier fluid, pigment-loaded acidic resin particles having a second color that is different than the first color, and a donor charge adjuvant. The dual color electronically addressable ink also includes at least one charge director.

  • Printing Conductive Patterns Using LEP
    Publication number: 20090085462
    Abstract: A method of printing an electrode component is disclosed. The method can include steps of electrostatically printing a polymer onto a substrate, where at least a portion of the printing occurs while the polymer is in a first conductive state, and altering the polymer to a second conductive state that is more conductive than the first conductive state, thereby forming the electronic component.
