ABSTRACT:
A large display sign, or analogous visual or radiant energy display or collecting surface area, is made up of numerous frontal individual "radiation sensitive" display elements arranged contiguously but in module groups, covering the full display area without gaps. The module unit occupying each such square is supported on a "tile" or equivalent base. Each base supports through bifurcate hinged connector (BHC) means an insulated multiple conductor power buss, a module area portion of a first or rear most circuit board or panel, and a group of insulating penetrating contacts with attached wires supported by this BHC between the base and the rear panel. At eight, symmetrically arranged around its center, each module comprises a BHC for each point and multiple contacts around each BHC, some connected to the penetrating contact wires. A second panel bears rearwardly and forwardly extending contact pins for electric contact with the rear and with a front panel. Supplemental electronic means which participate in the controlling function are mounted on the intermediate panel.
