A substrate assembly for a fluorescent or phosphorescent display panel comprises a layer of fired liquid gold, preferably three microns or less thick, for each of segmented display electrodes. The layer is in direct contact with an insulator substrate and with a mass of a luminescent material and may be an integral part of a lead for the electrode or electrodes. Alternatively, the layer may be formed on a resistive layer comprising powder of ruthenium (IV) oxide and formed, in turn, on the substrate with a conductive layer interposed for providing an electric connection to the lead.

Substrate assembly for a luminescent display panel having fired liquid

A substrate assembly for a fluorescent or phosphorescent display panel comprises segmented electrodes, for deposition thereon of masses of a fluorescent or phosphorescent material, respectively, on electroconductive leads disposed on a substrate of an electrically insulating material, such as glass or ceramics. Each segmented electrode comprises graphite powder bound into a mass by a zinc oxide containing vitreous material that does not substantially include lead. The segmented electrode may consist of an intermediate layer placed on each electroconductive lead and a segmented layer disposed on the intermediate layer.
