  • Publication number: 20110026045
    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: 7732810
    Abstract: An electronic device having a substrate structure having an undercut region is provided and further included is a method for forming an undercut region of a substrate structure. The method includes forming a patterned protective layer over a first electrode. The method also includes forming the substrate structure over the patterned protective layer. An opening within the substrate structure overlies an exposed portion of the substrate structure. The method further includes removing the exposed portion of the patterned protective layer, thereby exposing a portion of the first electrode and forming an undercut region of the substrate structure. The method still further includes depositing a liquid over the first electrode after removing the exposed portion of the patterned protective layer, and solidifying the liquid to form a solid layer.

  • Publication number: 20070040493
    Abstract: A process for protecting first electrodes, conductive leads and the underlying substrate from the process of removing organic layers during the fabrication of an organic electronic device. After first electrodes and conductive leads are formed over a substrate, a protective layer is selectively formed over the structure, with the protective layer not being disposed over selected portions of the first electrodes, the conductive leads and the substrate. Organic layers are then formed over the structure, and second electrodes are formed over the organic layers. Those portions of the organic layers disposed over the selected portions of the first electrodes, conductive leads and substrate are removed, and the protective layer protects adjacent portions of the first electrodes, conductive leads and substrate from the process of removing the portions of the organic layers.
