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.
Claims15
A vacuum-sealed flat panel display, comprising a middle plate spaced between an upper plate and a lower plate, defining an upper cavity above the middle plate and a lower cavity below the middle plate, and a divider block extending between the middle plate and the rear plate dividing the lower cavity into two compartments, each of the two compartments communicating with the upper cavity through at least one opening in the middle plate.
A flat panel display, comprising:
- a first component plate and a second component plate bonded together and defining a cavity between the plates;
- and
- at least one opening in one of the component plates for channeling cooling fluid through the cavity during manufacturing of said display.
A flat panel display, comprising:
- an upper plate, an intermediate plate and a lower plate, wherein an upper cavity is defined between the upper plate and the intermediate plate, and a lower cavity is defined between the intermediate plate and the lower plate;
- a divider separating the lower cavity into at least two compartments;
- an inlet opening and an outlet opening in the lower plate on opposite sides of the divider;
- and
- a pair of openings in the intermediate plate, one of said openings in the intermediate plate provided between a first of the two compartments and the upper cavity, and the other of said openings in the intermediate plate provided between a second of the two compartments and the upper cavity.
