  • Patent number: 6670753
    Abstract: A flat panel display is provided including a baseplate for carrying a first potential, the baseplate having emitters for emitting electrons positioned thereon and a faceplate for carrying a second potential, the faceplate having phosphors thereon. The baseplate and the faceplate are hermetically sealed around the periphery to define an evacuated volume. A gate electrode for carrying a third potential causes the emitter to selectively emit electrons, which cause the phosphors to emit light and which ionize contaminant gases in the evacuated volume. A gettering material is disposed in housing connected to the evacuated volume and has a getter connection connecting the gettering material to the baseplate for applying the first potential to the gettering material, which causes the ionized contaminant gases to be attracted to and absorbed by the gettering material. The getter connection extends outside the vacuum to allow for testing of the ionized contaminant gases.

  • Patent number: 6590338
    Abstract: An apparatus for removing contaminants from a display device using an auxiliary chamber, and a method for attaching the auxiliary chamber to the display device. In one embodiment, an auxiliary chamber is adapted to be coupled to a surface of a display device. The auxiliary chamber is adapted to be coupled to the surface of the display device such that contaminants within the display device can travel from the display device into the auxiliary chamber. The auxiliary chamber further includes a getter which is disposed therein. The getter is adapted to capture the contaminants once the contaminants travel from the display device into the auxiliary chamber. In so doing, the present invention eliminates the need for getter material to be placed within the active area of the display device. As a result, the present invention increases the usable amount of space available within the display device. This extra space can then be utilized by features such as, for example, additional field emitters.

    Abstract: Rare-earth halides are shown to be a replacement for scandium halides in mercury-free discharge arc lamps if modifications are made to the prior art lamp design and operating temperatures. The inventive chemical compositions of the discharge medium provide enhanced color rendition index values. In addition, it has been unexpectedly determined that during the operation of the discharge lamps, the rare earth iodides do not react significantly with the fused silica arc tube. Equally as significant, any free iodine, which is so formed, has minimal impact on the efficacy of the lamp compared to the conventional scandium iodide lamps. Therefore, the rare earth iodide-containing lamps provide longer lifetime with superior illumination characteristics than conventional discharge lamps.

  • Patent number: 6194830
    Abstract: A getter (74) is situated in an auxiliary compartment (72) of a hollow structure (40-46 and 76) having a larger main compartment (70). The auxiliary compartment is situated outside the main compartment and is connected to the main compartment so that the two compartments reach largely the same steady-state compartment pressure. The getter is activated by directing light energy locally through part of the hollow structure and onto the getter. The light energy is typically furnished by a laser beam (60). The getter, typically of the non-evaporable type, is usually inserted as a single piece of gettering material into the auxiliary compartment. The getter normally can be activated/re-activated multiple times in this manner, typically during sealing of different parts of the structure together.

  • Patent number: 6114806
    Abstract: A hermetic container which does not require a getter room and can reliably absorb gases released in a container. In a field emission display, the hermetic container contains a front substrate and an opposite substrate confronting each other and a spacer disposed between the outer fringes of the front substrate and the outer fringes of the opposite substrate. Stripe anodes are formed on the inner surface of the front substrate. Each anode is formed of a transparent anode conductor and a fluorescent substance layer. Field emission elements are formed on the inner surface of the opposite substrate and respectively have a cathode conductor, an insulating layer, a gate, and an emitter disposed in an opening. Each of supports has one end which is disposed between stripe anodes and is in contact with the front substrate and the other end which is disposed between stripe gates and is in contact with the insulating layer.

  • Patent number: 6104138
    Abstract: A frittable evaporable getter device includes a metallic container having a disk-shaped bottom wall and a side wall extending upwardly from the bottom wall. A powder compact having an upper surface in which at least two radial recesses are formed is disposed in the container. The powder compact is formed of a mixture of BaAl.sub.4 powder and nickel powder. A discontinuous metallic member is embedded in the powder compact such that the member does not protrude from the upper surface of the powder compact and the member is spaced apart from the bottom wall of the container. An evaporable getter device having reduced activation time includes a powder compact formed of a mixture of BaAl.sub.4 powder, nickel powder, and between about 0.3% and about 5% by weight based on the total weight of the mixture of a third component selected from aluminum, iron, titanium, and alloys thereof.

  • Patent number: 6100627
    Abstract: A Field Emitter Device (FED) having a substantially reducing atmosphere is described. The atmosphere in a FED can be maintained substantially free of oxidizing gases and includes a partial pressure of hydrogen between about 1.times.10.sup.-7 millibar (mbar) and 1.times.10.sup.-3 mbar. In one embodiment, a non-evaporable getter material previously charged with hydrogen gas is placed inside the FED before the FED is sealed. The non-evaporable getter material can be charged by exposure to hydrogen gas at a pressure between about 1.times.10.sup.-4 and about 2 bar. Subsequently, the components forming the FED are sealed, and the FED is evacuated and hermetically sealed to the outside atmosphere.

  • Patent number: 6016034
    Abstract: A method for forming a supported thin layer of non-evaporable getter (NEG) material and a getter device formed thereby are provided. A suspension comprised of non-evaporable getter (NEG) material particles in a dispersing medium is prepared. The NEG material particles in the suspension have a particle size not greater than about 150 .mu.m. The dispersing medium has an aqueous, alcoholic, or hydroalcoholic base and contains not more than about 1 wt % of organic compounds having a boiling temperature of at least about 250.degree. C. The ratio of the weight of the NEG material particles to the weight of the dispersing medium is between about 4:1 and about 1:1. A layer of the suspension is deposited on a carrier by a serigraphic technique. Next, the deposited layer is dried to evaporate volatile components of the dispersing medium and thereby form a dried deposit. Finally, the dried deposit is sintered under vacuum at a temperature between about 800.degree. C. and 1000.degree. C.
