Abstract: A support structure (3) is provided that enables use of high voltage phosphors in field-emission flat panel displays, to maintain vacuum gap (4) between the cathode (2) and anode (1), and to prevent distortion of the transparent view screen and backing plate of the display. A number of techniques contribute to the solution of the problem of secondary electron emission. In accordance with one technique, the geometry of the triple junction of the support structure, the cathode and the vacuum gap is altered. In accordance with another technique, the support structure is fluted so as to reduce the average coefficient of secondary emission. In another technique, a high resistivity conductive layer is formed at the triple junction in order to reduce electric field potential at the triple junction. In accordance with another technique, the support structure is made of a non-porous material and may be coated with a coating having low secondary emission characteristics.

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 flat panel display having a backplate structure (330), a faceplate structure (320), and a spacer (340) situated between the two plate structures is configured so that the electric potential field along the spacer approximates the potential field that would be present at the same location in free space, i.e., in the absence of the spacer, between the two plate structures. Consequently, the presence of the spacer does not significantly affect the trajectories of electrons moving from the backplate structure to the faceplate structures. Alternatively, the spacer is arranged to produce electron deflection that largely compensates for undesired electron deflection which occurs during earlier electron travel from the backplate structure to the faceplate structure. The net electron deflection is small.

Abstract: A method for reducing charge accumulation in a field emission display (100) includes the steps of causing a plurality of electron emitters (114) to emit electrons (132) to reduce the potential at an anode (124) of the field emission display (100). Upon the reduction of the potential at the anode (124), the electrons (132) neutralize a positively electrostatically charged surface (129) of a spacer (130). The anode potential is dropped by providing a resistor (127) in series with a voltage source (126) connected to the anode (124). The anode potential is reduced by causing the electron emitters (114) to emit simultaneously to provide a pull-down current (128) at the anode (124). The voltage at the anode (124) is reduced to a value that causes a sufficient flux of electrons (132) to be attracted to the charged surfaces (129) for neutralizing them.
