Abstract: A getter (50 or 74) situated in a cavity of a hollow structure, such as a flat-panel device, is activated by directing light energy locally through part of the hollow structure and onto the getter. The light energy is typically provided by a laser beam (60). The getter, typically of the non-evaporable type, is usually inserted as a single piece of gettering material into the cavity. The getter normally can be activated/re-activated multiple times in this manner, typically during the sealing of different parts of the structure together. The getter-containing cavity can be formed by a pair of plate structures (40 and 42) sandwiched around and outer wall (44), or by an auxiliary compartment (72) connected to a larger main compartment (70) typically constituted by the plate structures and outer wall.

Abstract: Portions (40 and 44) of a structure, such as a flat-panel display, are positioned such that a sealing area (40S) of one portion is at least partially separated from a corresponding sealing area (44S) of another portion such that a gap (48) at least partially separates the two sealing areas, typically by height of 25 microns or more. Energy is applied in a "gap jumping technique" to locally heat material of at least one portion along the sealing area such that the material bridges the gap and seals the portions (40 and 44) together. A laser is typically employed to locally melt and draw the material into the gap by a combination of factors such as surface tension and capillary action. A first part of the gap jumping technique may be performed in a non-vacuum environment to tack the portions together, but the gap jumping technique is typically completed in a vacuum to form an evacuated panel.
