    Abstract: The intensity at which electrons emitted by a first plate structure (10) in a slat-panel display strike a second plate structure (12) for causing it to emit light is controlled so as to reduce image degradation that could otherwise arise from undesired electron-trajectory changes caused by effects such as the presence of a spacer system (14) between the plate structures. An electron-emissive region (20) in the first plate structure typically contains multiple laterally separated electron-emissive portions (201 and 202) for selectively emitting electrons. An electron-focusing system in the first plate structure has corresponding focus openings (40p1 and 40p2) through which electrons emitted by the electron-emissive portions respectively pass. Upon being struck by the so-emitted electrons, a light-emissive region (22) in the second plate structure emits light to produce at least part of a dot of the display's image.

    Abstract: A method of removing contaminant particles in newly fabricated filed emission displays. Contaminant particles are removed by a conditioning process which includes the steps of: a) driving an anode (20) of a field emission display (FED) to a predetermined voltage; b) slowly increasing an emission current of the FED after the anode has reached the predetermined voltage; and c) providing an ion-trapping device for catching the ions and particles knocked off, or otherwise released, by emitted electrons (40). By driving the anode to the predetermined voltage and by slowly increasing the emission current of the FED, contaminant particles are effectively removed without damaging the FED. A method of operating FEDs is also provided to prevent gate-to-emitter current during turn-on and turn-off, which comprises the steps of: a) enabling the anode display screen (20); and b) enabling the electron-emitters (40) after the anode display screen is enabled. By allowing sufficient time for the anode display screen to reach a predetermined voltage before the emitter is enabled, the emitted electrons (40) will be attracted to the anode (20).
