frit or the like the seal 205 extends around at least a portion of the space between the substrate 200 and the faceplate 203 thus an enclosed chamber only a portion of which is shown is provided to retain the activatable material which preferrably is an appropriate gas such as neon argon fluorescent material or the like which produces the appropriate glow as desired also within the chamber are the electrical conductors 201a and 202a which may represent lead lines display elements i e anodes and or cathodes or the like this construction is conventional and is described in the prior art including the above mentioned patent to s t tang the internal conductors 201a and 202a are electrically joined to or continuations of the conductors 201 and 202 respectively the conductors 201 and 202 are referred to as conductor pads and are used inter alia as terminals for the display device 250 for example the substrate 200 extends beyond the edge of faceplate 203 thus the conductor pads 201 are in essence exposed in some instances the substrate 200 with the conductor pads 201 thereon is adapted to be inserted into a suitable receptacle or socket in other cases a suitable connector not shown is arranged to abut the conductor pads 201 the conductor pads 201 and 202 are selectively connected together by interconnect 225 in order to transfer.
