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 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 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.
