Abstract: The intensity at which electrons emitted by a first plate structure (10) in a flat-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 (42P1 and 42P2) 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 voltage ratio regulator circuit for a spacer electrode of a flat panel display screen. Within one implementation of a field emission display (FED) device, thin spacer walls are inserted between a high voltage (Vh) faceplate and a backplate to secure these structures as a vacuum is formed between. A phosphor layer on the faceplate receives electrons selectively emitted from discrete electron emitting areas along the backplate (cathode) thereby forming images on the faceplate. The faceplate warms relative to the backplate, as a result of energy released by the phosphor layer, thereby generating a temperature gradient along the spacer walls. The top portion of each spacer wall becomes more conductive with increased temperature and acts to attract electrons that are emitted toward the faceplate. To counter this attraction, a spacer electrode is placed along each spacer wall at a height, d, above the backplate and maintained at a voltage, Ve. Electrodes of all of the spacer walls are coupled together. The spacer electrode at Ve and the high voltage supply at Vh are both coupled to a voltage ratio regulator circuit which maintains the ratio (Ve/Vh) using voltage dividers, an operational amplifier and other circuitry. The voltage ratio regulator compensates for variations in voltage supply performance. The time constants of the voltage ratio regular circuit is tuned to be near or slightly faster than the time constant of the inherent resistance and capacitance of the spacer wall. The invention can also correct for other sources of the voltage error on the spacer walls. The invention improves the electron path accuracy for pixels located near spacer walls.

Abstract: A flat-panel display contains a pair of plate structure (20 and 22) separated by a spacer (24) having a rough face (54 or 56). When electrons strike the spacer, the roughness in the spacer's face causes the number of secondary electrons that escape the spacer to be reduced, thereby alleviating positive charge buildup on the spacer. As a result, the image produced by the display is improved. The spacer facial roughness can be achieved in various ways such as depressions (60, 62, 64, 66, 70, 74, or 80) or/and protuberances (82, 84, 88, and 92). Various techniques are presented for manufacturing the display, including the rough-faced spacer.
