  • the panel can thereby be constructed substantially as a conventional black and white plasma References Cited UNITED STATES PATENTS display device, and conventional addressing techniques may be utilized to provide a plasma display with multicolor capability.
  • 3,790,841 which is characterized in that at least two discharge spaces are provided which are separated from each other in the direction of discharge, that the conductors of a conductor field pair are disposed at an angle of about 60 in relation to each other, that the conductors of all conductor field pairs are disposed in three directions differing from each other by about 60, that in each of these directions discharge cells for two of the three basic colors are alternately arranged, one discharge cell for one basic color being common to two directions.
  • One disadvantage of this arrangement is that the apparatus while utilizing charge storage techniques is very complex in that it effectively incorporates two discharge panels in a single assembly and three separate sets of conductors are required to drive this assembly.
  • the subject invention effectively combines a novel technique for achieving color with conventional black and white plasma display techniques to achieve a multicolor display.
  • the triad arrangement of colored cells when selectively excited emit light in the basic colors of red, blue or green.
  • the individual cells are coincidently selected by horizontal and vertical selection circuits, the horizontal conductors being threaded through each cell of an associated triad in meandering form each of the vertical conductors being threaded through separate cells representing one of the three basic colors.
  • a second embodiment of the subject invention utilizes a similar triad configuration of cells of colored phosphor which, when selectively excited, emits light in the basic colors of red, blue or green.
  • FIG. 1 illustrates the triadic arrangement of basic color elements which for color display purposes is also used in television.
  • FIG. 2 illustrates the formation of the two conductor fields on the limiting planes of the arrangement opposite each other.
  • FIG. 3 illustrates the triadic arrangement of the basic colors and of the two associated conductor fields with transparent surfaces for observing additional visual information provided behind the arrangement.
  • FIG. 4 illustrates in schematic form a plasma display panel incorporating the triadic arrangement with associated horizontal and vertical selection and drive control circuitry.
  • FIG. 5 is a section view taken along the lines 55 of FIG. 4.
  • FIG. 6 illustrates an isometric view of the filter sheet used in the plasma panel illustrated schematically in FIG. 3.
  • FIG. 1 shows a prior art arrangement, of a configuration of cells which can be selectively energized to emit light in the basic colors red R, blue B, and green G.
  • each one of these elements can be selectively illuminated when impinged by the cathode ray.
  • the necessary mixed colors can be obtained.
  • FIG. 2 shows one arrangement of the parallel conductor array on one of the two surfaces defining the depth of the discharge chamber the vertical conductor array being shown in hatched representation.
  • These hatched vertical conductors designating a location on the lower plate of the display, as more fully shown in FIGS. 4 and 5, are divided into groups of three, each conductor being associated with cells representing a primary color R, B, G for the addressable coordinates YI-Y6.
  • R, B, G the addressable coordinates
  • YI-Y6 addressable coordinates
  • Conductors X1, X2 and X3 of the second array which are required for the X- definition of the individual selectively illuminable cells are shown in continuous lines in FIG.
  • a blue light emission can be effected at coordinate X2, Y3. If Y-conductor Y3/R is excited at the same time there is an illumination in the mixed colors of red and blue. In this manner, the corresponding individual or mixed colors can be excited at all coordinates.
  • the substantially vertical position of the two conductor with respect to each other is of particular advantage as compared to the three dimensional addressing of the above referenced US. Pat. No. 3,790,841. It permits conventional addressing with orthogonally arranged coordinates, is known in connection with conventional black and white display. This is also a prerequisite for compatibility between colored and black and white display which with respect to image generation and transmission.
  • a filter sheet of the type shown in FIG. 6 may be arranged over the entire display portion, said filter sheet having small limited areas designated R, B, G translucent for one of the three basic colors.
  • the filter sheet may be arranged in such a manner that it faces the observer.
  • a display device using a filter sheet coactng with a homogeneous light emission from a dis- :harge chamber as shown by the preferred embodinent of the subject invention does not have these distdvantages, and presents as an advantage the eliminaion of the need of using phosphors in various colors iroviding the multi-color image points.
  • Another advantage is the design of the intersections aetween the X and Y conductors in accordance with IG. 2. Since the firing of individual cells is confined to mall areas, cross talk between adjacent but nonelected cells is eliminated or substantially reduced.
  • FIG. 3 illustrates a special design of the conductor arrays and of the translucent light filter elements R, B, 3 arranged in the filter sheet.
  • This configuration provides, between the individual light emission cells, transparent areas 30 permitting display of additional visual information arranged behind the triads. However, since these transparent areas do not have conductors associated therewith, such information could be permanently recorded on these areas or projected through a rear projection system.
  • This device of FIG. 3 combines the advantages of a single chamber cooperating with a filter as specified above. By modifying the distances between the X-conductors and/or between the Y- conductor groups the resolution of the panel can be varied.
  • FIG. 4 there is illustrated a gaseous discharge display panel utilizing the techniques of the present invention for a multicolor display.
  • the display is shown as incorporating five horizontal conductors and six sets of vertical conductors.
  • the panel comprises an upper plate or substrate 21 on which a horizontal conductor array comprising conductors Xl-XS is formed, and a lower vertical plate 23 on which six sets of three vertical conductors Yl-Y6 is formed. Since the location of the translucent light filter elements coincides with the location of the light emitting areas, the filter sheet has been omitted from FIG. 5 in the interest of clarity. However, as obvious from FIG. 3 and preceding descriptions, the filter sheet is positioned over the upper surface of substrate 21.
  • the panel is addressed by horizontal selection and drive control circuitry 25, and vertical selection and drive control circuitry 27.
  • Such panels are constructed as fully described in the aforereferenced US. Pat. No. 3,837,734 and driven as fully described in the aforereferenced copending application Ser. No. 372,384. Reference is made to the above related patent and application for a more complete teaching.
  • FIG. 5 there is illustrated a sectional view of the display panel of FIG. 4 taken along the line meandering 5--5 of FIG. 4.
  • the upper and lower substrates 21-23 have conductors formed thereon, conductor X5 being visible on plate 21, conductor sets Yl-Y6 being shown in exaggerated width in the interest of clarity. Again, the filter sheet associated with substrate 21 has been omitted from the drawing in the interest of clarity.
  • the red, blue and green drive lines of Y1 are identified in FIG. 5 as R, B, G.
  • Formed over each of the X and Y conductors arrays is an associated dielectric layer 27, 29, respectively, which solate the conductors from direct contact with the gas in chamber 35. While not shown in FIG.
  • the surface of the dielectric layer may be refractory or incorporate a layer of refractory material having secondary emission characteristics such as described in copending application Ser. No. 176,626 (IBM Docket Ki9-7l-008) filed by P. H. I-laberland et al. for Improved Dielectric lnsulator for Gaseous Discharge Device", now abandoned.
  • the edges of the panel are sealed by seals 31-33, and the panel might incorporate spacers to maintain a uniform gas layer 35.
  • FIG. 6 illustrates an isometric view of the filter sheet illustrated schematically in FIG. 3.
  • the filter sheet has the triadic arrangement of red, blue and green filters, with transparent areas 30 covering the remainder of the filter sheet.
  • This sheet is associated with substrate 21 on which the horizontal conductors X, X, are formed, and is therefore on the viewing side of the panel.
  • This arrangement of filter elements in a polychromatic phosphor configuration has been fully described above.
  • first and second array producing discharge of the associated cell, said discharge producing a light emission corresponding to a selected color.
  • a gas discharge device for a multicolor information display having a gas composition within a discharge chamber which can be excited into illumination by means of ionization, wherein the opposing sides of said discharge chamber include first and second arrays of substantially parallel conductors,
  • each of said three conductors being suitable for exciting one of three adjacent cells in one of the three basic colors
