摘要： A flat-panel display is hermetically sealed by a process in which a first plate structure (30) is positioned generally opposite a second plate structure (32) such that sealing material (34) provided over the second plate structure lies between the plate structures. In a gravitational sealing technique, the first plate structure is positioned vertically below the second plate structure. The sealing material is heated so that it moves vertically downward under gravitational influence to meet the first plate structure and seal the plate structures together. In a global-heating gap-jumping technique, the plate structures and sealing material are globally heated to cause the sealing material to jump a gap between the sealing material and the first plate structure. When the first plate structure is positioned vertically above the second plate structure, the sealing material moves vertically upward to meet the first plate structure and close the gap.

摘要： 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.

摘要： A flat panel display includes a wall (103-102) which is held in place by a structure formed either on the faceplate (101) or on the backplate (210). In one embodiment, the supporting structure is formed by two adjacent walls that forms a slot which mechanically restrains the wall. In another embodiment, a slot is formed within the faceplate and the walls of the slot mechanically restrain the wall. In one embodiment, the wall segments are inserted into supporting structures that mechanically restrain each wall segment. In another embodiment, a UV curable adhesive is used to maintain walls in their proper alignment and position. The bond electrically connects conductive lines located on the wall and conductive lines located on the faceplate and maintains the wall in proper alignment.
