Abstract

The sealing glass frit for sealing a gas filler tube to a gas display panel is preformed in a desired shape around the tube. The frit is then fired to remove the binder, so that the tube with the sealing glass preform in place is ready to be sealed to the panel.

Cast in Place Preform for Gas Panel Tube Seal

The sealing glass frit for sealing a gas filler tube to a gas display panel is preformed in a desired shape around the tube. The frit is then fired to remove the binder, so that the tube with the sealing glass preform in place is ready to be sealed to the panel.

Tube 1, as illustrated in the drawing, is placed in holder 2 which is covered with a sheet of plastic 3. A glass frit paste or slurry 4 is then placed around tube
1. The slurry 4 can be molded to a desired shape such as a cone. The slurry is air dried and the plastic 3 is separated. The tube 1 and holder 2 is placed in a furnace under conditions of time and temperature sufficient to burn out the organic binder.

The process avoids the problem of panel contamination due to the binder and provides a seal preform tube structure which is rigid enough to be handled, and which has a shape chosen to provide a finished tube seal having good mechanical integrity.
