Definitions

  • ABSTRACT In a method for sealing a gaseous display and/0r memory device, an unfused, low-softening point glass rod sealant, arranged in a picture frame pattern, together with high-softening point glass spacing rods are positioned between a pair of aligned flat glass plates, and the resulting assembly is placed in an oven enclosure. The assembly is then heated above the softening point of the glass rod sealant which reflows and fuses the plates to establish a gas-filled envelope. As the sealing material softens, the upper plate settles u;on the spacing rods to thus establish a predetermined and uniform spacing within the envelope.
  • a gaseous display and/or memory device comprises an open panel configuration of electrically isolated but not physically isolated cells in which individual cells or sites are selected by energizing associated pairs of orthogonal drive lines disposed on opposite sides of a gasfilled envelope which, when appropriately and selectively energized, cause the gas in the sites between the selected conductors to ionize.
  • a gasfilled envelope In order to provide substantially uniform resolution over the entire display surface, it is essential that the space between opposing walls of the gas envelope be maintained substantially uniform and that the walls of the chamber be sealed to provide a gas-filled container. Ihitially, such panels were sealed using epoxy which produced outgassing, i.e., impurities in the gas mixture which substantially lowered the life of the panel.
  • the glass sealant material is selected to have viscosity sufficiently low to flow during the heat fusion cycling, and yet high enough so that it will not run off the voids during such cycling.
  • the panel is pumped down and backfilled during a bakeout operation to eliminate outgassing or other impurities, and the. tubular orifice projecting from one of the plates and utilized as a vehicle for evacnation and gas filling is tipped off, thereby sealing the gas within the panel.
  • vacuum and gas are coupled to the envelope while the exterior of the glass plates receives atmospheric pressure.
  • an object of the present invention is to provide an improved sealing method for a gaseous discharge device.
  • Another object of the present invention is to provide an improved gas panel assembly utilizing soft glass sealant and hard glass spacing rods.
  • An associated object of the present invention is to provide an improved process for providng a gas panel seal utilizing a soft glass rod sealant and a hard glass rod spacer wherein the upper plate settles upon the spacing rods during a bakeout operation thus establishing a predetermined and uniform spacing within the envelope.
  • FIG. I is a partially schematic perspective view of a gas panel constructed in accordance with the teaching of the instant invention.
  • FIGS. 24 are sectional views of the assembly of FIG. 1 before and after the heat fusion state of the assembly processing.
  • FIG. 5 is a schematic view of vacuum furnace apparatus utilized in the practice of the present invention to provide evacuation, gas-filling and heat-sealing stages.
  • FIG. 1 there is illustrated a gaseous discharge assembly fabricated in accordance with the teaching of the instant invention.
  • the panel assembly 1 consists of lower glass substrate 3 and an upper glass substrate 5 on which transverse passivated metallized conductor arrays 7 and 9, respectively, are formed.
  • Conductor arrays 7 and 9 may be formed on substrates 3 and 5 by a number of well-known processes such as photoetching, vacuum deposition, stencil screening, etc.
  • conductor arrays 7 and 9 may be wires or filaments of copper, gold, silver, aluminum or any other conductive metal or material, formed in situ conductor arrays of transparent, semi-transparent or opaque conductive material are preferred since they are more easily deposited on and adhered to the substrates 3, 5.
  • opaque chrome-copper-chrome conductors having a split conductor configuration such as that described in the foregoing application Ser. No. 214,348 are utilized in one of the conductor arrays as the preferred electrode configuration for maximum light output. While not evident in FIG. 1 since they are transparent, each of the conductor arrays 7 and 9 have dielectric layers 11 and 13 (FIG. 3) formed thereon.
  • the two metallized passivated dielectric coated front and rear glass plates 3 and 5 and exhaust tube 15 are formed into an integral structure by heat union of rod sealant 17 with dielectric plate coatings 11 and 13 of glass substrates 3 and 5, respectively.
  • the broken-away portion of FIG. 1 indicates an edge spacer rod 23, one of which would be utilized around each edge in the preferred embodiment shown in FIG. 1.
  • the fused seal is indicated in the broken-away section of FIG. 1 as element 25.
  • the dielectric layers 11 and 13 (FIG. 2), formed from sprayed and heated glass frit, cover the conductor arrays indicated schematically as 7 and 9 in FIG.
  • All glasses used in the fabrication of the subject panel such as the substrate, dielectric layers, orifice, orifice sealant, border sealant, etc., must have compatible thermal coefficients of expansion, albeit differing optical, physical, dielectric and heat-softening properties.
  • the glass substrates 3 and 5 have substantial thickness (e.g. onefourth inch), the only requirement for such support members being that they be nonconductive and good insulators and substantially transparent for display purposes. Ordinary inch commerical grade soda-limesilica glass is utilized in the preferred embodiment. While the panel illustrated in FIG. 1 is representative of a panel after scaling in accordance with the instant invention, reference is made to FIGS. 2-4 for a more complete description of the operation of the sealing process.
  • FIG. 2 the relative position of the glass plates 3 and 5 with their associated dielectric coated conductor arrays prior to the sealing process is illustrated. While shown exaggerated for ease of understanding, the relative size of sealing rod 17 with respect to the spacing rod 23 is illustrated. In a preferred embodiment constructed in accordance with the instant invention, the soft glass sealant 17 is approximately 40 mils in diameter, while the spacer rod 23 is approximately 7 mils in diameter. However, as noted previously, the configuration of the rods may vary, and other configurations of both sealing and spacing rods such as rectangular rods could be substituted for the circular rods illustrated in the preferred embodiment. When laid out in the general configuration shown in FIG.
  • the component parts of the panel are placed in an oven which is then heated to a temperature sufficient to produce wetting or melting of the low-softening point envelope sealant 17 which, as previously described, comprises in the preferred embodiment a single rod in the form of a picture frame positioned outside the normal display area of the panels.
  • the peripheral spacer rod 23 could comprise a single rod in the same general picture frame configuration or four or more separate spacer rods.
  • the unjoined assembly when positioned in the desired orientation shown generally in FIG. 2, is placed in an oven enclosure and then heated in accordance with the sequence more fully described hereinafter such that the soft glass sealant 17 softens, flows and fuses with the dielectric metallization coating layers 13 and 11.
  • the sealing rods are positioned beyond the viewing area of the panel and thus beyond the conductor configurations comprising conductor arrays 7 and 9, although this is not a requirement.
  • the upper plate 5 gradually settles against spacers 23, establishing the desired final dimensions of the gasfilled sealed envelope contained between the plates. While the weight of the upper plate 5 is normally adequate, a glass weight providing a pressure of up to 5 lbs. per square inch throughout the sealing area may be added to upper plate 5. Thickness and viscosity of the unfused envelope sealant are selected so that upon softening and flowing the sealant forms a uniform void-free lining around the rectangular parallelepiped gas enclosure space shown within the sealed area bounded by seal 25 in FIG. 1.
  • FIG. 3 An enlarged view of the left seal in FIG. 3 is illustrated in FIG. 4, and it will be appreciated that an identical sealing operation and sequence would simultaneously take place along the four edges to be sealed within the panel.
  • FIG. 5 the apparatus for providing the pumpdown, bakeout and backfill operation re-' quired to fabricate a gas panel is illustrated schematically in FIG. 5.
  • the gas from a gas source 29 is applied through conduit 31 and valve 33 to a metering valve 35 which controls the gas to the desired pressure.
  • a metering valve 35 which controls the gas to the desired pressure.
  • an electronic manometer 37 is also connected to the metering valve 35 to a vacuum system.
  • a mechanical pump comprising a portion of the vacuum system creates an initial vacuum below 50 TOR, while a diffusion pump also conventional creates a higher vacuum in the area of 10 to 10 TOR.
  • a bakeout cycle is provided in oven enclosure 41 to eliminate any remaining impurities within the gas panel, and following the vacuum bakeout the panel is backfilled with gas from the gas source 29.
  • the apparatus of FIG. 1 is considered adequate for an understanding of the present invention.
