摘要： A flat panel display includes a faceplate and an opposing backplate. The two are sealed together and a sealed envelope is created that includes an active area of length L.sub.1. The active layer includes addressable pixels on the faceplate. Spacers are perpendicular to the faceplate and backplate. The length of a spacer is in a direction parallel to the plane of the faceplate. At least one spacer is positioned in the envelope and provides rigidity to the display. This is required because of the high vacuum which is maintained within the envelope. One or more electrodes are formed on an exterior surface of the spacer. The electrodes extend a length of L.sub.2 along a side of the spacer that is at least equal to L.sub.1. Voltages applied to the electrodes are controlled to achieve a desired voltage distribution between the backplate and the faceplate. The electrode is made of a material with a sheet resistance of less than about 10.sup.5 to 10.sup.7 .OMEGA./.quadrature.. The potential drop across the spacer between the faceplate and the backplate can be tailored by the selection of the position of the electrodes on the spacers, as well as the potentials applied to the electrodes. An additional way of tailoring the potential drop is selecting a desired thickness or conductivity of the spacer from top to bottom.

摘要： 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.

摘要： A voltage-adjustment section (20) of an electronic device converts an input control voltage (V.sub.1) into an output control voltage (V.sub.0) in such a way that a collector current (I.sub.CP) form with electrons emitted from an emitter (EP) of an emission/collection cell (26), or triode, varies in a desired, typically linear, manner with the input control voltage. The triode further includes a collector (CP) that carries the collector current and a gate electrode (GP) that regulates the collector current as a function of the output control voltage. Control of the collector current so as to achieve the desired current/voltage relationship is achieved with an analog control loop containing the triode and an amplifier (28) coupled between the triode's collector and gate electrode. The triode thus typically has a linear gamma characteristic relative to the input control voltage. The voltage-adjustment section is suitable for use in a display device such as a flat-panel display.

摘要： A spacer (44) for a flat-panel display is formed with a main spacer portion (60), typically shaped like a wall, and a face electrode (66) situated over a face of main spacer portion. The spacer is inserted between two opposing plate structures (40 and 42) of the display. The face electrode causes electrons moving from one of the plate structures to the other to be deflected in such a manner as to compensate for other electron deflection caused by the presence of the spacer. The face electrode is divided into multiple laterally separated segments (661-66N) to improve the accuracy of the compensation along the length of the spacer. A masking step is typically utilized in defining the widths of the segments of the face electrode.

摘要： A flat panel display is disclosed which includes a faceplate with a faceplate interior side, and a backplate including a backplate interior side in an opposing relationship to the faceplate interior side. Side walls are positioned between the faceplate and the backplate. The side walls, faceplate and backplate form an enclosed sealed envelope. A plurality of phosphor subpixels are positioned at the faceplate interior side. A plurality of field emitters are positioned at the backplate interior side. The field emitters emit electrons which strike corresponding phosphor subpixels. A plurality of scattering shields surround each phosphor subpixel and define a subpixel volume. The scattering shields reduce the number of scattered electrons exiting from their corresponding subpixel volume. This reduces the number of scattered electrons from charging internal insulating surfaces in the envelope, as well as striking the non-corresponding phosphor subpixels.
