Abstract: An electron-emitting device (20, 70, 80, or 90) contains an electrode, either a control electrode (38) or an emitter electrode (32), having a specified portion situated off to the side of the bulk of the electrode. For a control electrode, the specified portion is an exposure portion (38EA or 38EB) having openings that expose electron-emissive elements (50A or 50B) situated over an emitter electrode. For an emitter electrode, the specified portion is an emitter-coupling portion situated below at least one electron-emissive element exposed through at least one opening in a control electrode. Configuring the device in this way enables the control-electrode-to-emitter-electrode capacitance to be quite small, thereby enhancing the device's switching speed. If the specified portion of the electrode becomes short circuited to the other electrode, the short-circuit defect can be removed by severing the specified portion from the remainder of its electrode.

Abstract: 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.
