<p>A two dimensional illuminated display for forming on an expansive surface such as an airship envelope comprises (FIG. 3) a set of one dimensional display components 18 each formed by a multiconductor (ribbon) cable 19 having attached thereto by insulation piercing connectors 41 a plurality of display elements 20 containing illumination elements 20R and 20G formed by arrays of red and green high intensity l.e.d.'s. The display component cables hang from an attachment point at one end of the cable (21, FIG. 2) and are retained in channels 15, formed on the surface by raised vertically-extending ribs 16, by retaining members 24 extending across the channels by way of through-apertures 25 in the ribs. The retaining members are prevented from withdrawal by similar joining members 26 extending along the ribs. Each illumination element is fed from the cable 19 and the emission axes of the diodes may be tilted relative to the local channel base e.g. by tilting the housing, to align the elements of a display formed on a non-flat surface. The display elements may be other than illuminated and may be non-energizable.</p> |
