Abstract

Plasma display panels generally consist of two sealed glass plates, having orthogonal transparent conductors disposed on the outer surfaces thereof, wherein symbols are generated as a sequence of illuminated spots by simultaneous energization of selected coordinate conductors. An alternate plasma display panel construction shown in enlarged section in the upper drawing includes an electrically insulated glass back plate 1 and an insulated transparent glass front plate 3. The back plate has a set of "column" conductors 5 and a set of "row" conductors 7. Rather than transparent surface conductors, conductors 5 and 7 comprise a central electrically conductive core or solid conductor 9 surrounded by a bonded or fused glass coating 11.

Gas Panel Display Device

Plasma display panels generally consist of two sealed glass plates, having orthogonal transparent conductors disposed on the outer surfaces thereof, wherein symbols are generated as a sequence of illuminated spots by simultaneous energization of selected coordinate conductors. An alternate plasma display panel construction shown in enlarged section in the upper drawing includes an electrically insulated glass back plate 1 and an insulated transparent glass front plate 3. The back plate has a set of "column" conductors 5 and a set of "row" conductors 7. Rather than transparent surface conductors, conductors 5 and 7 comprise a central electrically conductive core or solid conductor 9 surrounded by a bonded or fused glass coating 11. The inwardly facing surface of back plate 1 is provided with grooves 13, 15 in which the conductors 5 and 7 are disposed. A first set of parallel grooves 13 extends orthogonally to a second set of parallel grooves 15, the grooves 13 being formed at a greater depth in the back plate 1 than the grooves 15. The intersection of conductors 5 and 7 form a plurality of crosspoints 17. This arrangement permits joining the front and back plates in assembling the panel without affecting the critical space between conductors 5, 7. The grooves 13 have enlarged areas 19 at each crosspoint and enlarged cavities 21 between crosspoints as shown in the lower drawing. When the conductors 5 are placed in the grooves 13, holding me...
