Abstract
The present invention features flat-panel displays having a mosaic of tiles, and methods of constructing and sealing them. Sealing designs are described to maintain appropriate vacuum levels for FEDs, PFPDs and LCDs. The mosaic of tiles forming a flat-panel display may include subassembly tiles, with each consisting of two, unsealed, substantially parallel plates having a structure positioned between them; these are known as s-tiles. The tiles may be enclosed by a cover plate and backplate. Non-permeable material may be deposited on the cover plate and the backplate, with solderable metal overlaid on the non-permeable material. A metallized, non-permeable spacer/connector is also located between the cover plate and backplate for hermetically sealing the perimeter of the display. A set of electrical-interconnection, metal feed-throughs can also be positioned in the non-permeable spacer/connector. A flat-panel display may also be made up of half-tiles (h-tiles), with each including an individual bottom plate with a structure disposed on them. The mosaic of tiles also has a cover plate that is shared in common with all of the h-tiles. This common cover plate for each type of FPD integ…
