An evacuated cavity is hermetically sealed between a baseplate and faceplate of a flat panel display. Melting a glass powder, or frit, on the perimeter of the viewing area forms the hermetic seal. After melting the frit, a first fluid is circulated through the cavity to speed cooling. To further expedite the cooling of the flat panel display, a second fluid flows externally along the contour of the flat panel display to insure that the cooling is uniform and thereby avoid thermal shock.

Flat panel display, method of high vacuum sealing

A field emission display includes electrostatic discharge protection circuits coupled to an emitter substrate and an extraction grid. In the preferred embodiment, the electrostatic discharge circuit includes diodes reverse biased between grid sections and a first reference potential or between row lines and a second reference potential. The diodes provide a current path to discharge static voltage and thereby prevent a high voltage differential from being maintained between the emitter sets and the extraction grids. The diodes thereby prevent the emitter sets from emitting electrons at a high rate that may damage or destroy the emitter sets. In one embodiment, the diodes are coupled directly between the grid sections and the row lines. In one embodiment, the diodes are formed in an insulative layer carrying the grid sections. In another embodiment, the diodes are integrated into the emitter substrate.
