Abstract

A publication entitled "Flat Spacer Rods for Gas Panel", IBM Technical Disclosure Bulletin, Vol. 16, No. 7, December, 1973, page 2057, describes gas panel assemblies including spacer rods for establishing the dimension between the plates. As described in that publication, such spacers can be used at both peripheral and medial positions within the panel.

Gas Panel Spacer Assembly

A publication entitled "Flat Spacer Rods for Gas Panel", IBM Technical Disclosure Bulletin, Vol. 16, No. 7, December, 1973, page 2057, describes gas panel assemblies including spacer rods for establishing the dimension between the plates. As described in that publication, such spacers can be used at both peripheral and medial positions within the panel.

Particularly in the case of medial spacers, it is important that the rods maintain their positions during assembly with utmost precision, so as to avoid intrusion into the portions of the gas space which are operative with respect to the electrode arrays of the panel.

To provide this precision, grooves can be cut in the panel subassembly to receive and maintain the rods in position during the assembly and sealing operations in the manufacture of the panel.

Referring to the drawings, one plate of a gas panel assembly is illustrated with the panel broken away. This panel subassembly comprises glass substrate 5 with orthogonal array conductors 9 having dielectric coating 13. The spacer rod 17 is in position to control the distance between plates and a companion plate, generally as in the cited publication. The diameter of a typical spacer rod 17 to be partly embedded as in this publication is about 5 mils.

In the manufacturing process, the substrate 5 has a conductor layer applied thereto, which is then etched to provide conductor lines such as 9. Next, dielectric layer 13 is applied, initia...
