Abstract

Conventional AC plasma display panels are fabricated by metallizing glass plates by vacuum evaporation, delineating conductor patterns by photolithography, overcoating and reflowing a dielectric glass, vacuum depositing a refractory oxide film over said dielectric, installing appropriate spacers, assembling two plates with conductor lines substantially orthogonal, sealing, vacuum exhausting and backfilling with an inert gas. A new process eliminates vacuum metallizing and photolithography steps and the spacer requirement from the above-described process.

Flat Display Panel Fabrication Process

Conventional AC plasma display panels are fabricated by metallizing glass plates by vacuum evaporation, delineating conductor patterns by photolithography, overcoating and reflowing a dielectric glass, vacuum depositing a refractory oxide film over said dielectric, installing appropriate spacers, assembling two plates with conductor lines substantially orthogonal, sealing, vacuum exhausting and backfilling with an inert gas. A new process eliminates vacuum metallizing and photolithography steps and the spacer requirement from the above-described process.

This process improvement is accomplished by weaving a composite cloth of metal and glass in the configuration illustrated generally in Fig. 1 and positioning the woven material within the panel. Referring to Fig. 1, a plurality of vertical conductors 11, 13, 15, 17 are interwoven with vertical glass fibers 14, 16 and horizontal glass fibers 19 through 23, the conductors comprising metal wires or ribbons. Vertical glass fibers 14, 16 and horizontal glass fibers 19-23 are included in the illustrated mesh configuration by way of example, since the ratio of conductors to fibers can be varied to any desired mesh configuration. Further, the mesh for a single plate is illustrated, although in practice individual meshes would be required for the horizontal and vertical conductor array. A side view of the specific conductor configuration for vertical conductor 11 and associated horiz...
