  • Publication number: 20110260741
    Abstract: Capacitive sensing devices are provided that include a sensing pattern of conductive traces disposed upon the surface of a substrate and a first passive circuit element that includes a metallic conductor disposed upon the same surface of the substrate. In some embodiments, the first passive circuit element is a component of an electronic circuit that can be, for example, a low pass filter. Provided capacitive sensing devices are useful, for example, when incorporated into projected touch screen display panels for use on electronic devices.

  • Publication number: 20110226733
    Abstract: A patterning process comprises (a) providing at least one substrate having at least one major surface; (b) providing at least one patterning composition comprising at least one functionalizing molecule that is a perfluoropolyether organosulfur compound; (c) applying the patterning composition to the major surface of the substrate in a manner so as to form at least one functionalized region and at least one unfunctionalized region of the major surface; and (d) etching at least a portion of the unfunctionalized region.

  • Publication number: 20100258968
    Abstract: An ink solution comprises (a) a solvent having (i) a boiling point between about 50° C. and about 100° C., (ii) a relative polarity of less than about 0.4, and (iii) a poly(dimethylsiloxane) swelling ratio of less than about 1.25; and (b) one or more dissolved organosulfur compounds, wherein each organosulfur compound has 10 or more carbon atoms. The one or more organosulfur compounds are present in a total concentration of at least about 3 mM, and the ink solution contains essentially no solid particles of the organosulfur compounds or solid particles derived from the organosulfur compounds.

  • Publication number: 20090219257
    Abstract: A touch screen sensor includes a visible light transparent substrate and an electrically conductive micropattern disposed on or in the visible light transparent substrate. The micropattern includes a first region micropattern within a touch sensing area and a second region micropattern. The first region micropattern has a first sheet resistance value in a first direction, is visible light transparent, and has at least 90% open area. The second region micropattern has a second sheet resistance value in the first direction. The first sheet resistance value is different from the second sheet resistance value.

  • Publication number: 20090218310
    Abstract: A method of patterning a conductor on a substrate includes providing an inked elastomeric stamp inked with self-assembled monolayer-forming molecules and having a relief pattern with raised features. Then the raised features of the inked stamp contact a metal-coated visible light transparent substrate. Then the metal is etched to form an electrically conductive micropattern corresponding to the raised features of the inked stamp on the visible light transparent substrate.
