摘要： A method for forming a three-dimensional multi-level conductive matrix structure for a flat panel display device. In one embodiment, the present invention forms first pixel separating structures across a surface of a faceplate of a flat panel display. The first pixel separating structures separate adjacent first sub-pixel regions. In this embodiment, the first pixel separating structures are formed by applying a first layer of photo-imagable material across the surface of the faceplate. Next, portions of the first layer of photo-imagable material are removed to leave regions of the first layer of photo-imagable material covering respective first sub-pixel regions. Then, a first layer of conductive material is applied over the surface of the faceplate such that the first layer conductive material is disposed between the aforementioned regions of the first layer of photo-imagable material. The present invention then removes the regions of the first layer of photo-imagable material leaving only first pixel separating structures formed of the first layer of conductive material, disposed between the first sub-pixel regions. The present invention performs similar steps in order to form second pixel separating structures between the second sub-pixel regions. The second pixel separating structures are formed substantially orthogonally oriented with respect to the first pixel separating structures and, in the present embodiment, have a different height than the first pixel separating structures. In so doing, a three-dimensional multi-level conductive matrix structure is formed.

摘要： Methods and structures are provided which support spacer walls (100) in a position which facilitates installation of the spacer walls (100) between a faceplate and backplate of a flat display. In one embodiment, spacer feet (111, 112) are formed at the opposing ends of the spacer wall. Tacking electrodes can be provided on the faceplate to assert an electrostatic force on the spacer feet (111, 112), thereby holding the spacer feet in place during installation of the spacer wall. The spacer wall can be mechanically and/or thermally expanded prior to attaching both ends of the spacer wall to the faceplate. The spacer wall is then allowed to contract, thereby introducing tension into the spacer wall which tends to straighten any inherent wavines in the spacer wall. Alternatively, spacer clips can be clamped onto opposing ends of a spacer wall to support the spacer wall during installation. The spacer clips can provide electrical connections to face electrodes located on the spacer wall.

摘要： 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.

摘要： 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).
