Abstract

Conventional gaseous discharge display/storage devices require a substantially uniform four-mil glass spacing between the inner walls of the gas panel, such a chamber gap being normally achieved with hard glass spacer rods. As the gaseous discharge display/storage devices gradually increase in size, manipulation of the sealing frames and spacer rods in the fabrication process becomes quite cumbersome, and the panels more difficult to fabricate with a uniform chamber gap.

Gas Discharge Panel With Built In Cavity

Conventional gaseous discharge display/storage devices require a substantially uniform four-mil glass spacing between the inner walls of the gas panel, such a chamber gap being normally achieved with hard glass spacer rods. As the gaseous discharge display/storage devices gradually increase in size, manipulation of the sealing frames and spacer rods in the fabrication process becomes quite cumbersome, and the panels more difficult to fabricate with a uniform chamber gap.

This method for fabricating a gaseous discharge display/storage panel uses either a ground or pressed cavity provided in the base plate section of the panel for the gas chamber. Referring to the drawing, a gaseous discharge display/storage panel is composed of glass substrates 1 and 2 on which orthogonal conductors 4 and 5 have been formed, each conductor array being insulated from direct contact with the gas by layers of dielectric 6 and 7, respectively. A four-mil chamber gap 8 is provided in glass substrate 2 through conventional hot pressing, molding or grinding techniques, the outline of the cavity being designated 10.

The panel is completed with sealing glass frit at point 9, which when fired in a furnace cycle provides for edge sealing the panel. When completed, the appropriate gas of a specified pressure and mixture is inserted in the chamber through tubulation 11, after which the tubulation is tipped off. The cavity could be provided in the upper...
