Abstract
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.
