Abstract

Typical gas-display panels include self-focusing of the discharge generated in the panel. Parallel aluminum electrodes are deposited on a glass substrate and a dielectric layer is deposited over the electrodes. over the dielectric layer is placed an electron emissive layer to form an assembly. Two such assemblies are crossed at 90 degrees and are sealed with a spacer and a suitable sealant around the edges.

Dielectric Layer for a Gas Panel Assembly

Typical gas-display panels include self-focusing of the discharge generated in the panel. Parallel aluminum electrodes are deposited on a glass substrate and a dielectric layer is deposited over the electrodes. over the dielectric layer is placed an electron emissive layer to form an assembly. Two such assemblies are crossed at 90 degrees and are sealed with a spacer and a suitable sealant around the edges.

A method for improving the operation of the glass panel, as well as diminishing its manufacturing cost, comprises making an assembly by depositing metal lines 2, such as chromium, copper or gold, onto a glass substrate 4, the lines serving as electrodes in the selection of gaseous areas in the display. A layer of aluminum 6 is evaporated over the metal pattern and such aluminum is anodized throughout its thickness. This anodized aluminum serves as the dielectric layer of each assembly of the gas panel, and electron emissive material can either be deposited on the anodized layer or incorporated therein.

The two assemblies, when joined together to form a gas panel, will have the benefit of an anodized layer of aluminum, whose properties will not change at the sealing temperatures needed to seal the two assemblies, thus protecting the original alignment of the metal lines 2.
