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.

Methods and structures are provided which support spacer walls (100) in a position which facilitates installation of the spacer walls (100) between a faceplate and backplate of a flat display. In one embodiment, spacer feet (111, 112) are formed at the opposing ends of the spacer wall. Tacking electrodes can be provided on the faceplate to assert an electrostatic force on the spacer feet (111, 112), thereby holding the spacer feet in place during installation of the spacer wall. The spacer wall can be mechanically and/or thermally expanded prior to attaching both ends of the spacer wall to the faceplate. The spacer wall is then allowed to contract, thereby introducing tension into the spacer wall which tends to straighten any inherent wavines in the spacer wall. Alternatively, spacer clips can be clamped onto opposing ends of a spacer wall to support the spacer wall during installation. The spacer clips can provide electrical connections to face electrodes located on the spacer wall.

A flat panel display including a wall (590) in one embodiment includes 98 % alumina and a refractory metal, such as, 2 % titania, for increased thermal conductivity. Alternatively, the refractory metal may be molybdenum, niobium, tungsten, or nickel. The wall may further include cordierite, or zirconia.

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.

Seal material bars and methods for forming seal material bars, a seal material frame, and method for forming a flat panel display using the same. Bars of seal material (1101-1104) are made by extruding a mixture of glass frit and organic compound. In one embodiment, the glass frit bars have joining features (1111-1118) formed in them. Ceramic material is also extruded so as to form seal material bars. The seal material bars are placed between the backplate and the faceplate and glass frit slurry may be placed between adjoining seal material bars. A heating step melts the seal material so as to form a seal interior region. Alternatively seal material bars may be joined in a first step to form a seal material frame. A further embodiment comprises extrusion of a hollow rectangular shape of seal material which is cut crosswise into integral seal material frames.
摘要:
A light-emitting device (52, 80, 110, 128, or 130) suitable for a flat-panel cathode-ray tube display contains a light-emissive region (66) formed over a plate (64). The light-emissive region contains a plurality of light-emissive particles (72). Part of the outer surface of each light-emissive particle is conformally covered with one or more coatings (74, 82, 84, 112, and 114). The coatings variously provide light-reflection, gettering, intensity-enhancement, and contrast-enhancement functions.
