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 light-emitting device is provided with getter material (58) that can readily be distributed in a relatively uniform manner across the device's active light-emitting portion. An electron-emitting device is similarly provided with getter material (112, 110/112, 128, 132, and 142) that can readily be distributed relatively uniformly across the active electron-emitting portion of the device. Techniques such as thermal spraying, angled physical deposition, and maskless electrophoretic/dielectrophoretic deposition can be utilized in depositing the getter material.
Abstract:
A method of fabricating a support structure (118). In one embodiment, the method is comprised of providing a mold (220). The mold (220) is for defining the physical dimension of the support structure. The mold (220) is disposed upon a substrate surface (210). In one embodiment, the method is further comprised of depositing a powder (230) into the mold (220). The present method is further comprised of compacting the powder (230) deposited in the mold (220). The compacting forms the support structure (118). In one embodiment, the method is further comprised of removing the mold (220) from the substrate surface (210) upon which it is disposed. The removal of the mold (220) exposes the support structure (118). The fabricated support structure (118) is then implementable during assembly of a display device (100). In one embodiment, the powder (230) deposited in the mold (220) is a metal powder (230).
Abstract:
The present invention provides a spacer assembly (100) which is tailored to provide a secondary electron emission coefficient of approximately 1 for the spacer assembly (100) when the spacer assembly (100) is subjected to flat panel display operating voltages. The present invention further provides a spacer assembly (100) which accomplishes the above achievement and which does not degrade severely when subjected to electron bombardment. The present invention further provides a spacer assembly (100) which accomplishes both of the above-listed achievements and which does not significantly contribute to contamination of the vacuum environment of the flat panel display or be susceptible to contamination that may evolve within the tube. Specifically, in one embodiment, the present invention is comprised of a spacer structure (102) which has a specific secondary electron emission coefficient function associated therewith. The material comprising the spacer structure (102) is tailored to provide a secondary electron emission coefficient of approximately 1 for the spacer assembly (100) when the spacer assembly (100) is subjected to flat panel display operating voltages.
Abstract:
An apparatus for removing contaminants from a display device (400) is disclosed. In one embodiment, an auxiliary chamber (408) is adapted to be coupled to a surface of a display device (400) such that contaminants within the display device can travel from the display device into the auxiliary chamber. A getter (410) is disposed in the auxiliary chamber (408). The getter is adapted to capture the contaminants once the contaminants travel from the display device (400) into the auxiliary chamber (408). In other embodiments, the getter is disposed in the border region surrounding the active area of the display.

Abstract:
A light-emitting device (42, 68, 80, 90, or 100) suitable for a flat-panel CRT display contains a plate (54), a light-emissive region (56), and a light-reflective layer (60 or 70). The light-emitting device achieves one or more of the following characteristics by suitably implementing the light-reflective layer or/and providing one or more layers (72, 82, 92, and 100) along the light-reflective layer: (a) reduced electron energy loss as electrons pass through the light-reflective layer, (b) gettering along the light-reflective layer, (c) reduced secondary electron emission along the light-reflective layer, (d) reduced electron backscattering along the light-reflective layer, and (e) reduced chemical reactivity along the light-reflective layer.
