Abstract

The gas panel display structure shown in the figure uses a getter film frame around the periphery of the active region in order to minimize contamination from the frame seal itself, and from small leaks therein. The getter film acts to trap impurities before they reach the active region. In addition, the getter film frame acts to eliminate the stress due to the fulcrum effect typically present in gas panel structures.

Gas Panel Display Structure

The gas panel display structure shown in the figure uses a getter film frame around the periphery of the active region in order to minimize contamination from the frame seal itself, and from small leaks therein. The getter film acts to trap impurities before they reach the active region. In addition, the getter film frame acts to eliminate the stress due to the fulcrum effect typically present in gas panel structures.

In order to fabricate the structure shown, the plate-glass substrate 1 is first deep-etched to a depth h (one half of the required gap space), establishing mounds of remaining glass comprising a rectangular outer frame 3 and a few islands 5 within the active region, as shown in the side view of Fig. 1.

As shown in the top view of Fig. 2, the frame 3 acts to circumscribe the active region and the four islands 5a-5d. As is evident, the opposing plate-glass substrate 1 is likewise deep-etched to a depth h to be in registry with the plate shown. The frame seal represented by 7 acts to seal the opposing plates together.

The metallurgy for the panel is buried in shallow grooves etched into the plate-glass substrate 1. This may be done after the deep-etching step so that the metal lines traverse up and over frame 3, as shown by 9 in Fig. 3. Alternatively, the metal lines may be buried in shallow grooves etched in the plate glass substrate before the deep-etching step. Since the deep-etching step will act to etch away the lines within the deep-etched region, new lines are deposited, as represented by 11 in the r...
