Large scale display
First Claim
1. A two dimensional display formed on a surface of a structure comprising a set of channels defined on the surface by pairs of shoulders raised with respect to the channels, the channels each extending along one dimension of the display and the set extending along the second dimension, a plurality of one-dimensional display components each comprising a multiconductor electrical cable having elements, each comprising at least one illumination element, attached to appropriate conductors thereof at intervals along its length and located in an individual channel of the set, retaining means comprising for each channel a plurality of retaining members held by said shoulders at a plurality of points along the channel length and extending across the display components operable to retain each of the display means operable to supply energising signals to the display components in accordance with the formation of a desired two-dimensional display of illumination elements.

Abstract
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.
