Definitions

  • a gas discharge panel having a pair of elongated rectangular glass plates, each carrying on one surface a conductor array consisting of spaced parallel conductors running in the long direction of the plate and a dielectric coating on selected portions of the conductors of the array.
  • the plates have long axes transverse to each other and are spacedly joined and sealed along an endless seal line defining a thin gas chamber in an active panel area, the seal being substantially along the edges of the long sides of the plates, the plates being of a length sufi'icient such that both lateral ends of the plates project beyond the active panel area and beyond the long side edges of the opposite plate member.
  • Alternate conductors of each array are extended toward the edge of one side edge extension, respectively, the ends of alternate conductors of an array being terminated substantially short of the edge of the panel to permit slip-on or edge connectors to be applied to the conductors which do extend to the edge of the plates.
  • the present invention relates to gaseous discharge and/or display/memory devices and is characterized in that a pair of elongated glass support plates are joined in spaced apart relation with the long axes transverse to each other, the lateral edges in the long direction of each plate extending beyond the side edges of an opposing plate in the short direction of the plates.
  • Conductor arrays on each of the plates having individual linear conductors parallel to the long axes of each plate, and extending toward the ends of the lateral edges in alternate fashion to provide room to make electrical connection to the conductor arrays, respectively, alternate conductors being extended on alternate sides, beyond the seal joining the two plates in spaced-apart relation and forming the edge walls of a thin gas discharge chamber.
  • the conductors extending to the lateral edges may be oriented and grouped in any desired fashion so as to accommodate one or more circuit connectors much in the same fashion as edge connectors for printed circuit boards.
  • FIG. 1 is a front-elevational view of a gas discharge panel incorporating the invention shown substantially to scale of a panel having about a 4-inch display area.
  • FIG. 2 is a top plan view.
  • FIG. 1 there is disclosed a gas discharge display and/or memory panel constituted by a pair of elongated rectangular glass plates 11 and 12 having conductor arrays 13 and 14, respectively, on opposing surfaces thereof and thin dielectric films or coatings l5 and 16 over the conductor arrays 13 and 14, respectively.
  • An endless seal-spacer member 17 spacedly joins the two plate members with the long axis, respectively, of the plate members being at 90 to each other so that ends I2 U and 12 B of plate 12 extend beyond edges 11 U and 11 B of plate 11; and the ends 11 L and 11 R extend beyond the side edges 12 L and 12 R of plate I2.
  • the seal 17 forms with the opposing surfaces of dielectric coatings l5 and 16, respectively, the bounding walls of a thin gas discharge chamber in which is confined under pressure a gaseous discharge medium such as for example a mixture of neon and argon or a mixture of neon and nitrogen or any other gaseous mixture which is capable of being discharged on application of suitable potentials to selected conductors of the conductor array, and at the same time produce a copious supply of charges (ions and electrons) which are alternately collectable on the surfaces of dielectric members and 16 at opposed or facing elemental or discrete areas defined by nongas contacting sides of the dielectric members as described in Baker et al. U.S. Pat. No. 3,499,167.
  • a gaseous discharge medium such as for example a mixture of neon and argon or a mixture of neon and nitrogen or any other gaseous mixture which is capable of being discharged on application of suitable potentials to selected conductors of the conductor array, and at the same time produce a copious supply of charges (ions and
  • All of the electrically operative structural members such as dielectric All 15 and 16 and conductor arrays 13 and 14 as well as the thickness of the gas between the opposing or facing surfaces of dielectric coatings l5 and 16 are all relatively thin and the conductor members per se are fon'ned on and supported by the rigid nonconductive support members 11 and 12.
  • Both of said support members or plates 11 and 12 are constituted by quarter-inch-thick commercially available polished plate glass, as for example commercially available soda lime glasses have been used.
  • Conductors (usually gold, but not limited thereto) are printed on the plate members by silk screening process, photoetching or any other process for printing conductors or conductor arrays.
  • conductor arrays 13 are printed on 30-mil centers and conductor array 14 are printed on similar 30-mil centers so that in a 4-inch panel display area there are a total of some 17,000 discharge points in the panel, e.g., discrete discharge cross points defined by the crossing of one conductor in conductor array 14 and one conductor in conductor array 13.
  • Thickness of the conductive material forming conductor arrays 13 and 14 is very small being in the order of a fraction of a mil thick (about 0.] to 0.5 mil) and 2 to 6 mils wide.
  • the thickness of dielectric layers or coatings l5 and 16 is likewise very small being usually below l to 2 mils thick.
  • the spacing between the facing surfaces of the dielectric is likewise very small being of the order of under 10 mils thick and usually between about 4 and 6 mils and is determined by the spacer elements, shown as spacer rods 19, 20 and 21 and spacer sealant 25 of FIG. 1.
  • Other forms of spacers may be used, as for example, small bead spacers shown in Baker et al. U.S. Pat. No. 3,499,167.
  • alternate conductors in conductor array 13 are extended toward the laterally extended end 11 R or side of plate 11 and alternate adjacent conductors in array 13 are extended to the laterally extended end 11 L of plate 11. While in FIG. 1 the conductor ends are shown extending to the edges of the plates, it is to be understood that they may terminate short of the edges but beyond the ends of the alternate conductors.
  • the identical conductor arrangement scheme is applied to conductor array 14 on plate 12 and, in fact except for gasfilling tubulation 40 on plate ll, plate 12 is identical to plate I l.
  • the extended conductor ends are divided into groups, e.g., l3 R-Gl, l3 R-G2, l3 L-Gl and 13 L-G2.
  • each conductor group only one conductor is completely without angulation namely conductors l3 R-GlA, l3 R-G2A, l3 L-GlA and I3 L-G2A; the remaining conductors are angled at such amounts and direction so that each group is separated from each other.
  • This permits use of separate edge connectors for the individual groups, much in the same fashion as is applied to edge connectors for printed circuit boards.
  • the comer edges of each plate is bevelled as at B, which bevelling, in addition to removing sharp edges also facilitates applying edge connector strips to the panel conductor groups.
  • Tubulation 40 is applied to plate II in a direction normal to the plane thereof by providing a counterbore 41 having a diameter to receive the end of tubulation 40.
  • a smaller bore hole 42 completes communication to the thin gas chamber formed in the panel.
  • a glass sealant 43 is applied about the perimeter of tubulation 40 to provide a hermetic seal.
  • Tubulation 40 is used during vacuum bake-out of the panel to remove contaminants and to admit the operating gas mixture after which it is tipped off in the manner shown.
  • the length L, of plate II is greater than its width W, and the length L of plate 12 is greater than its width W and the width W of plate 12 is less than the length L, of plate 11.
  • plates 1] and 12 have identical dimensions and long axes at resulting in a square gas discharge chamber and display area, it will be appreciated that this is not necessary.
  • W, and W are different, an elongated rectangular display area results and when the long axes are at transverse angles other than 90 (and not parallel), the display areas will be diamond shaped.
  • length L, of plate 11 may be extended to be a multiple of width W of plate 12 and a plurality of plates similar to plate 12 spacedly sealed to plate II to form a plurality of individual discharge gas chambers, the conductor array 13 cooperating with a plurality of conductor arrays 14.
  • the lateral ends 11 R and 111. may be extended and the conductor ends angled 90 toward edge ll 8 so that edge connection for array 13 may be applied to the panel on edge 11 B.
  • dielectric coatings l and 16 are solder glass materials that are screened on to the plates in the form of a glass frit which is cured in place.
  • the spacer sealant 25 is a ceramic material applied after curing of dielectric coating and 16. After spacer sealant 25 is fired to cure same, the tubulation 40 applied, the entire assembly is annealed. Throughout the process and particularly during the curing of dielectric coatings l5 and 16, there is a possibility that one or more of lines of conductor in the array may open or acquire an abnormal resistance. Ends 30 are available for purposes of making electrical continuity tests and resistance measurements on the panel conductors after fabrication is completed or at any stage in the manufacturing process following curing of dielectric coatings 15 and 16.
