Definitions

  • an object of the present invention is to .-the thickness (andweight) of present glass substrata provide a simpler gas panel assembly process and product structure characterized by elimination of formation and handling of special exhaust ,connections to the envelope contained in the structure.
  • An associated object is to provide improved gas panel display stuctures of uniformly flat construction which can be stacked adjacently in layers to form three-dimensional displays.
  • a further object is to provide a gas panel display structure having uniformly flush surfaces without pro jections; whereby one surface of the structure may be conveniently arranged for viewing as a display while the opposite surface may be positioned-in contactwith photocopying equipment for contact printing of hard copy of displayed images.
  • Another object is to reduce significantly the time and cost of fabricating a gas panel display structure.
  • Another object is to reduce the possibility of gas panel failure by eliminating tubular exhaust/gas filling couplings and associated seals which inherently tend to be thermally and mechanically mismatched in relation to other elements of a panel assembly.
  • the foregoing and other related objectives are achieved by arranging high softening point glass spacing rods and low softening point glass-sealing material in picture frame pattern between disjoint high softening point glass plates within a vacuum oven enclosure.
  • the oven is adapted for selective coupling of vacuum, gas and heat into its enclosure.
  • the disjoint assembly is thereby successively scrubbed by vacuum, immersed in the gas which forms the light emitting medium of the display panel, and heat-fused while immersed in the gas.
  • the blass sealing material fuses with the plates to form a containing envelope around the gas surrounded by these elements.
  • the sealing material softens the upper plate collapses gradually towards and settles upon the spacing rods (diameter less than initial thickness of the unfused sealant); establishing the desired predetermined spacing of the envelope.
  • the sealing material is selected to have viscosity sufficiently low to flow during heat fusion cycling and yet high enough so that it will not run off and leave voids during such cycling.
  • additional objects of the present invention are to provide for improved display panel fabrication processing under conditions of reduced pressure stress whereby glass parts forming the bulk of the panel structure may be made with reduced thickness; such being desirable for both economy, and general effectiveuess of light transmission and handling;
  • FIGS. 1 and 4 provide contrasting partially schematic perspective views of gas panel assemblies formed respectively by earlier and present methods (FIG. 4 serves to indicate the elimination of the exhaust tube and the relatively reduced thickness of the glass plates forming the gas enclosure);
  • FIGS. 2 and 3 provide sectional views of the assembly of either FIG. 1 or FIG. 4 respectively before and after the heat fusion stage of assembly processing;
  • FIG. 5 is a schematic view of vacuum furnace apparatus utilized in the practice of the present invention to provide equalized pressure handling of the assembly throughout the in situ evacuation, gas-filling and heat sealing stages of the present process;
  • FIGS. 6 and 7 indicate additional uses which can be made of the flush rear surfaces of gas panels formed by the present method.
  • FIGS. 1 and 4 show earlier and present gas panel assemblies. The respective fabrication/assembly processes are compared as follows:
  • Vacuum oven enclosure successively exhausted at room temperature, filled with Ne-A gas mixture atspe cific pressure (700 torr), heated (at temperature cycle of note 3 above) to establish envelope sealant fusion and, upon cooling to room temperature, restored to ambient pressure.
  • Exhaust cycle pressure reduced from atmospheric pressure (approx. 750 ton) to about 10 torr in about 5 minutes, and from 10 torr to between 10 and 10 torr in about another hour.
  • Alternate process sequence a) evacuate enclosure; b) heat enclosure to temperature T(C) below softening point (400 C) of envelope sealant and dielectric plate coatings; 0) supply gas plasma to oven enclosure at elevated pressure T/25 X 700 torr; d) continue oven temperature cycle, per note 3, from T to 500 C and back to room temperature; e) restore oven enclosure to atmospheric pressure.
  • the metallized-passivated-dielectric coated front and rear glass plates 1, 2 and exhaust tube 3 are formed into an integral structure by heat union of envelope sealant 4with dielectric plate coatings 5, 6 and heat union of tube sealant 7 with tube 3 and plate 2.
  • edge spacer rods such as 8 may be supplemented by a not shown central spacer rod providing central support for the glass plates during subsequent evacuation and gas filling of envelope space 9 (FIG. 3) through tube 3 and hole 10 in plate 2 (FIG. 3) with the parts subject externally to atmospheric pressure.
  • the fused dielectric layers 5, 6, formed from sprayed and heated glass frit cover the patterned metallization (indicated schematically at 11 in FIG.
  • Layers 5, 6 have specific dielectric properties requisite to support of gas plasma discharge in envelope space 9. All glasses (substrate, dielectric layers, tube, tube sealant, border sealant) must have compatible thermal coefficients of expansion, albeit differing optical, physical, dielectric, and heat softening properties. The expense and effort involved in the exhaust and back filling operation are considerable.
  • the projecting exhaust tube structure 3 is also a relatively weak element in comparison to the main body of the panel formed by glass parts 1, 2.
  • Tube 3 also restricts contact between the exterior surface of plate 2 and other media; for instance other panels as suggested in FIG. 6 or hard copy photocopying equipment as suggested in FIG. 7.
  • Glass plates 1, 2 must have substantial thickness (e.g. one-fourth inch) and may require potentially obstructive central support rods in order to be able to withstand the differential pressures existing when envelope space 9 is evacuated while atmospheric pressure exists externally.
  • FIGS. 4, 2 and 3 Gas panels processed in accordance with the present invention have the form exemplified in FIGS. 4, 2 and 3.
  • Peripheral spacer rods such as 8a having higher softening temperature than the envelope sealant establish ultimate separation spacing of the fused glass parts.
  • the unjoined assembly is positioned in the desiredorientation (FIG. 2) within vacuum oven enclosure 16 (FIG. 5), associated with gas supply apparatus l8, l9, vacuum coupling apparatus 20 and heating unit 22.
  • gas supply apparatus l8, l9 gas supply apparatus 20 and heating unit 22.
  • Such ovens without the gas supply fittings, are sold under commercial designation High Temperature Vacuum Oven, Model 1408, by T-M Vacuum Products Co.
  • the unfused envelope sealant 4a permits unimpeded evacuation of the extended envelope space 26 bounded by the unjoined plates when enclosure 16 is evacuated and unimpeded permeation of gas into the same space when oven enclosure 16 is filled with gas.
  • envelope sealant 4a softens, flows and fuses with the dielectric metallization coating layers 50, 6a of the plates as suggested at 30 (FIG. 3), while the upper plate sinks down against spacers 8a establishing the desired final dimensions of the gas-filled/sealed envelope 9a contained between the plates. 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 parellepiped gas enclosure space 9a.
  • Typical parameters of the present process are:
  • A1,0,-0.2 percent We have shown and described above the fundamental novel features of our invention as applied to a preferred embodiment.
