Abstract

In the manufacture of gaseous-discharge display panels, it is conventional to mate two glass plates, such as the plates 10 and 11 in Fig. 1, by a perimeter sealing process. The plates include confronting, orthogonally positioned, but spaced apart, conductive lines (not shown) thereon forming grid matrices which, when energized, form spots at the intersections for forming characters. In order to accomplish the finished end product, the plates are sealed in spaced-apart relation, one from the other, a predetermined distance, and when filled with an argon-neon mixture, may be ignited to facilitate the gaseous discharge display.

Spacer Rods and Seals for Gaseous Discharge Display Panels

In the manufacture of gaseous-discharge display panels, it is conventional to mate two glass plates, such as the plates 10 and 11 in Fig. 1, by a perimeter sealing process. The plates include confronting, orthogonally positioned, but spaced apart, conductive lines (not shown) thereon forming grid matrices which, when energized, form spots at the intersections for forming characters. In order to accomplish the finished end product, the plates are sealed in spaced-apart relation, one from the other, a predetermined distance, and when filled with an argon-neon mixture, may be ignited to facilitate the gaseous discharge display.

It is also conventional to place seal rods adjacent the periphery of the glass of the front plate, and locate spacer rods within the periphery so that, when process conditions are met, the softer seal rods will melt allowing the upper or back plate 10 to collapse until it abuts the spacer rods. A problem occurred with the spacer rods moving around within the space or cavity during the processing steps. By making a frame of the seal rods, as shown in Fig. 1, and providing an axially extending notch 13 in the seal rods 12, the spacer rods 14 may be placed in the notch, thereby preventing or inhibiting their movement adjacent the periphery of the panel during handling and seal reflow. After the panels have been brought to the seal rod reflow temperature, the back plate 10 will move downw...
