Abstract

The fragility of glass exhaust tubes mitigates against fabricating a plurality of panels through backfill and burning-in as a multiple panel, as well as cutting the panels prior to test. Backfilling a co-sealed array of gas discharge panels is accomplished by substituting metal tubulations for the normal fragile glass exhaust tubulation. Referring to the figure, a small diameter tubing 1 of glass sealing material such as Ni-Fe alloy, one per panel, is sealed into the multiple array of co-sealed panels by seal 2 during the panel sealing process. The entire array, which may consist of several dozen panels, is threaded into the backfill portholes 3. This is facilitated by having a stress relief section 4 in the tubulation.

Method for Multiple Panel Backfill

The fragility of glass exhaust tubes mitigates against fabricating a plurality of panels through backfill and burning-in as a multiple panel, as well as cutting the panels prior to test. Backfilling a co-sealed array of gas discharge panels is accomplished by substituting metal tubulations for the normal fragile glass exhaust tubulation. Referring to the figure, a small diameter tubing 1 of glass sealing material such as Ni-Fe alloy, one per panel, is sealed into the multiple array of co-sealed panels by seal 2 during the panel sealing process. The entire array, which may consist of several dozen panels, is threaded into the backfill portholes 3. This is facilitated by having a stress relief section 4 in the tubulation. After completion of the backfill process, the tubulations are pinched off at 5, using conventional tube "pinch-off" procedures. The panel array is then separated into individual panel entities by scribing and snapping at glass surface 6. This may be done either prior to or after panel burn-in but prior to panel test.
