Abstract
A method of evacuating and sealing the space between the baseplate and the faceplate of a field emission display. A frit bead is formed around the perimeter of the baseplate, and is then heated to a temperature at which a plurality of surface irregularities are formed on the surface of the bead. After the faceplate is placed on top of the frit bead, the panels are placed in a vacuum, and the space between the plates is evacuated through gaps in the frit bead formed by the surface irregularities. After the space between the plates has been evacuated, the frit bead is heated to a temperature that is high enough to allow the frit to at least partially flow. A compressive force applied between the plates compresses the frit bead, thereby bonding the frit bead to the plates. The plates are then allowed to cool before removing the plates from the vacuum.
