Gas Panel Spacer Technology

In fabricating a gas panel, two aligned flat glass plates are sealed at their edges to establish an impermeable envelope capable of confining a predetermined volume of gas.

Generally, high-softening point glass spacing rods are positioned inside the gas discharge room near a low-softening point glass rod sealant arranged in a picture frame pattern. The assembly is heated to a temperature above the low- softening point of the sealant but below the high-softening point of the glass rod sealant, which then reflows and fuses the glass plates.

In order to avoid separate handling of the high-softening point glass spacing rods and the low-softening point glass rod sealant, high-softening point spacing means in the form of glass rods, globules or granulated material with suitable properties are originally incorporated in the glass joint binder serving as a low- softening point sealant. Even metallics or ceramics can be used for these high- softening point spacing means.

Sealant strips containing these components are placed around the outer edges of the glass plates. After the assembly has been heated up, the sealant reflows and the upper plate settles on the spacing means which are laterally still enclosed in sealant material.

In an alternative version, high-softening point glass spacing rods are positioned outside the gas discharge room directly adjacent to the low-softening point glass rod sealant strip, which is larger and higher than the s...
