    摘要: 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.

    摘要: A flat-panel cathode-ray tube display contains electron-emissive regions (54) spaced non-uniformly apart from one another in a line of the electron-emissive regions so as to better utilize the space where the electron-emissive regions are located. Alternatively or additionally, electron focusing can be appropriately made more concentrated by implementing each electron-emissive region as two or more portions 54A-54F) situated suitably with respect to openings (86A-86F) in an electron-focusing system (76).
