  • Publication number: 20110100683
    Abstract: The invention relates to an electronic textile comprising a textile substrate having a substrate electrode, and an electronic component having a component electrode. The component electrode is in electrically conductive contact with the substrate electrode via a coupling layer having a directionally dependent conductance so as to preferentially allow an electrical current to flow between the substrate electrode and the component electrode. As the coupling layer does not have to be patterned to prevent the occurrence of parasitic electrical currents, the electrically conductive contact between the substrate electrode and the component electrode has an improved reliability.

  • Publication number: 20100238637
    Abstract: A submount for arranging electronic components on a substrate is provided. The submount comprises a head member and at least one substrate-engaging member protruding from the head member. The head member comprises at least two, from each other isolated, electrically conductive portions, where each electrically conductive portion comprises a component contact, adapted for connection of electronic components thereto, and a substrate contact on arranged on said substrate side, adapted for bringing said electrically conductive portions in contact with a circuitry comprised in said substrate. The submount of the present invention may be used to attach electronic components, such as light-emitting diodes, to a textile substrate, without the need for soldering the electronic component directly on the substrate.

  • Publication number: 20100109981
    Abstract: A cut-to-measure display device (100) comprising a plurality of pixel groups (200-223), each including a plurality of individually controllable pixels, and a pixel group controller (230) adapted to control each of the pixels in the pixel group (200-223). The cut-to-measure display device (100) further comprises a display controller (235) configured to control the pixels, via the pixel group controllers (230), to display an image corresponding to pre-determined image data, and a communication bus (236) comprising a plurality of bus lines (301, 304) interconnecting the display controller (235) with each of the pixel group controllers (230). Each of the pixel group controllers (230) is configured to determine locations of functional pixels in its associated pixel group (200-223), and communicate information indicative of the locations of functional pixels to the display controller (235) to enable adjustment of the image data for display of the image by means of the functional pixels.
