Gas Display Panel

A structure has been devised for use in the pumping stem of a gas display panel, in which a getter is supported for removing gas contaminants from a gas display panel.

In the fabrication of a gaseous display panel device, two glass substrates having dielectric coated conductor arrays are positioned such that the conductors are orthogonal to each other, and sealed about their edges to form a gas container or envelope. The gas is applied under appropriate pressure through a tubulation to the panel. This tubulation is employed as a support for a gettering material.

As seen in Fig. 1, only one of the glass substrates 2 that forms part of the completed gas discharge panel is shown. Within a region of such substrate a hole 4 is made. It is through this hole that the panel will be evacuated, and it is through this same opening that the illuminating gas for the gas discharge panel will be pumped.

Within, but not closing off, the opening is located a support 6 that holds the getter material 8 in the form of a ring. Suitable gettering material is a barium-aluminum alloy.

In Fig. 2 is shown a container 10, which contains solder glass melt 12 that is of the identical material that will be used to fuse the two substantially identical panels (only panel 2 is shown). Prior to fusing the panels together, a pumping stem 14 is dipped into the solder glass melt 12 when it is in its molten state, so that solder glass tips 16 (see Fig. 3) remain on the pumping stem....
