US 5,667,418 A · Method of fabricating flat panel device having internal support structure

Abstract

A flat panel device is provided with an internal support structure in the form of a spacer. In one fabrication technique, the spacer is formed as a laminate of multiple layers of ceramic, glass-ceramic, ceramic-reinforced glass, devitrified glass, or/and metal coated with electrically insulating material. The spacer is placed between a backplate structure and a faceplate structure which are connected together to form an enclosure that encases the spacer. In another fabrication technique, the spacer constitutes a spacer wall placed between the backplate and faceplate structures. When the backplate structure is connected to the faceplate structure to form an enclosure that encases the spacer wall, the spacer wall follows a corrugated path adjacent to at least one of the faceplate and backplate structures.

Dependent claims

A method comprising the following steps for fabricating a flat panel device:

forming a spacer as a laminate of a plurality of layers of at least one of ceramic, glass-ceramic, ceramic-reinforced glass, devitrified glass, and metal coated with electrically insulating material;
placing the spacer between a backplate structure and a faceplate structure;
and
connecting the backplate structure to the faceplate structure to form an enclosure that encases the spacer such that the spacer supports the backplate and faceplate structures against forces acting in a direction towards the enclosure.
