  • Patent number: 9738816
    Abstract: A process including providing a coating head having an external opening in flow communication with a source of a first coating liquid, positioning the coating head relative to a substrate to define a gap between the external opening and the substrate, creating relative motion between the coating head and the substrate in a coating direction, and dispensing a predetermined quantity of the first coating liquid from the external opening onto at least a portion of at least one major surface of the substrate to form a discrete patch of the first coating liquid in a predetermined position on at least a portion of the major surface of the substrate. The first coating liquid as dispensed exhibits a viscosity of at least 1 Pascal-sec. In some exemplary embodiments, the first coating liquid is a liquid optically clear adhesive composition used in a laminate including a light emitting or reflecting device component.

  • Publication number: 20170142841
    Abstract: Electrically conductive patterns formed on a substrate are provided with a reduced visibility. A region of a major surface of the substrate is selectively roughened to form a roughened pattern on the major surface of the substrate. Electrically conductive traces are directly formed on the roughened region and are conformal with the roughened pattern on the major surface of the substrate.

  • Publication number: 20150309353
    Abstract: A process including positioning a coating head to define a gap between a first external opening in flow communication with a source of a first coating liquid, and a major surface of a substrate; creating relative motion between the first coating head and the substrate; dispensing a pre-determined quantity of the first coating liquid to form a discrete patch in a predetermined position on the substrate's major surface; positioning a second coating head to define a gap between a second external opening in flow communication with a source of a second coating liquid and a major surface of the patch; creating relative motion between the second coating head and the substrate, and dispensing a pre-determined quantity of the second coating liquid to form a discontinuous pattern on the patch's major surface. The first and optionally the second coating liquids exhibit a viscosity as dispensed of at least 1 Pascal-sec.

  • Patent number: 8911582
    Abstract: An apparatus to facilitate the application of a micro-contact printing stamp to a roll. The apparatus preferentially constrains some of the stamp's six degrees of freedom, and then drives the stamp (or the assembly of the stamp and the master against which it was formed) into controlled contact with the printing roll so as to attach the stamp onto the outer surface of the roll.

  • Publication number: 20140319194
    Abstract: An apparatus (20) for steering a web (22), including a web path having at least one steering roller (24) and an exit roller (26), each having a mount; wherein the steering roller(s) (26) each have an axis of rotation and wherein the mounts for the steering roller(s) (26) can pivot those axes with a total of two degrees of freedom. An array (30) comprising a plurality of sensors (30a) for monitoring the position of the web (22) is present connected to a controller so as to determine the position and angular orientation of the web (22). The controller adjusts the pivot(s) of the mount(s) so as to control the angular orientation and the lateral position of the web (22) at a particular point along the web path.

  • Patent number: 8720052
    Abstract: A method of applying a conductive pattern of metal onto a web of indefinite length material. This method includes applying a metal containing composition onto the web in a predefined pattern, providing a roll having a very low thermal mass, and conveying the patterned web around the roll while simultaneously applying heat energy to the metal containing composition thereby converting the metal to a conductive pattern. This allows for flexible circuitry to be fabricated in an inexpensive roll-to-roll process.

  • Publication number: 20130009329
    Abstract: A manufacturing system includes a sensing system that provides high-resolution feedback for web guiding and tension control. The system may be especially useful for web material that is manufactured to include micro-replicated structures with micron size scale. A micro-replication station forms a pattern of micro-replicated lenses on a web material. The sensing system illuminates a measurement area on the web material and detects an angular distribution of light exiting a set of the micro-replicated lenses within the first measurement area. A control system that adjusts at least one process control parameter of the transport system based on the detected angular distribution.
