  • Patent number: 9149830
    Abstract: A liquid replenishment system includes a dispensing vessel for holding a supply of a liquid that has an outer can and corresponding lid conjoinable to the outer can in an air-tight manner. The dispensing vessel is improved by the provision of a separate self-supporting secondary inner container removably receivable within the outer can. The container is fabricated of a material that is non-reactive with a liquid composition containing an organic semiconductor material, such as a polytetrafluoroethylene material or stainless steel.

  • Patent number: 8616666
    Abstract: There is provided a method of printing a regular array of rows of subpixels on a workpiece. The subpixels have c different colors and have a subpixel pitch s. A printing head has z nozzles arranged in a row with a spacing p, where z=n1(c) and p=n2(s), the printhead being at a first position relative to the workpiece. There are c different printing inks, one for each of the c colors, and each of the printing inks is supplied to the nozzles in a regular alternating pattern. The method includes steps of printing a first set of z rows of subpixels with the printing head; moving the workpiece laterally relative to the printing head by a distance d1, where d1=n3(s); printing a second set of z rows of subpixels with the printing head; repeating the printing steps for a total of n2 sets of z rows of subpixels. Variables include: c, an integer greater than 1; n1, n2, and n3 which are the same or different and are independently selected from integers greater than 0, with the proviso that n2 is not a multiple of c.

  • Patent number: 8033883
    Abstract: An organic electronic device includes a first electrode layer, an organic resistive layer coupled to the first electrode layer wherein the organic resistive layer defines at least three regions, an organic active layer coupled to the organic resistive layer, and a second electrode layer coupled to the organic active layer. Each of the at least three regions is characterized by one of the plurality of resistances and the plurality of resistances includes at least three discrete resistances that are different from one another. The regions can be fabricated by selectively exposing portions of the organic resistive layer to a chemical, selectively removing portions of the organic resistive layer, or depositing a plurality of blends.
