摘要： A flat panel device (300) includes a spacer (308) for providing internal support. The spacer can be made of ceramic or glass-ceramic. Spacer surfaces exposed within the flat panel device are treated to reduce secondary emissions and prevent charging of the spacer surfaces. A light-emitting structure contains a main section (302), a pattern of dark ridges (314) situated along the main section, and a plurality of electron-activated light-emissive regions (313) situated in spaces between the ridges. The dark ridges extend further away from the main section than the light-emissive regions to form a raised black matrix. When the light-emitting structure is used in an optical display, the raised black matrix contacts spacers (308) and, in so doing, protects the light-emissive regions from being damaged. The light-emitting structure can be formed according to various techniques of the invention.

摘要： 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.

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.

摘要： A flat-panel device is fabricated by a process in which a pair of plate structures (40 and 42) are sealed along their interior surfaces (40A and 42B) to opposite edges (44A and 44B) of an outer wall (44) to form a compartment. Subsequently, exterior support structure (64) is attached to the exterior surface of one of the plate structures (40) to significantly increase resistance of the compartment to bending. Exterior support structure (66) is normally likewise attached to the exterior surface of the other plate structure (42) after the sealing operation. The compartment is then typically pumped down to a high vacuum through a suitable pump-out port (46) and closed. By providing the exterior support structure at such a relatively late stage in the fabrication process, the need for using spacers to support the device against external forces is eliminated or substantially reduced while simultaneously avoiding severe fabrication difficulties that arise in attaching the exterior support structure before the sealing operation.

摘要： The invention provides spacers for separating and supporting a faceplate structure and a backplate structure in a flat panel display, and methods for fabricating these spacers. Each spacer is typically made of ceramic, such as alumina, containing transition metal oxide, such as titania, chromia or iron oxide. Each spacer can be fabricated with an electrically insulating core and electrically resistive skins. The insulating core can be a wafer formed of ceramic such as alumina, and the resistive skins can be formed by laminating electrically resistive wafers, formed from alumina containing transition metal oxide, to the outside surfaces of the insulating core. Each spacer can also have a core of electrically insulating ceramic composition made of a ceramic containing a transition metal oxide in its higher oxide states, and electrically resistive outside surfaces made of a ceramic containing a transition metal oxide in lower oxide states. Face and/or edge metallization strips can optionally be provided on each spacer.

摘要： 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.
