Abstract:
PROBLEM TO BE SOLVED: To facilitate to mount a spacer wall between a face plate and a back plate of a flat panel display. SOLUTION: A coupling electrode is installed on the face plate so that an electrostatic force may be added on spacer stands 111, 112. By this, the spacer stands are supported at a constant position during mounting of the spacer wall. Since the spacer wall is expanded mechanically and/or thermally, a tensile force useful to correct waving distortion of the spacer wall is given to the spacer wall so that it can be contracted.

Abstract:
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.
Abstract:
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.
Abstract:
A flat panel display and a method for forming a flat panel display uses a low temperature glass frit deposit (101). In one embodiment the assembly (102) is heated to a low frit sealing temperature of about 220 degrees centigrade in a vacuum by step (104) to form a tubeless seal. The low temperature frit allows for melting of the glass frit at a temperature lower than that of prior art processes. Also, process steps associated with evacuation through an evacuation tube are eliminated.
