Definitions

  • a flat display panel which comprises an insulating substrate provided with a plurality of parallel slots, a plurality of anodes for subsidiary discharge each of which is disposed in each of the slots, a plurality of anode lines for main discharge disposed upon the insulating substrate, an insulating layer laid over the anode lines and provided with a plurality of openings so as to expose only the desired portions of the anode lines, a plurality of cathode plates disposed in contact with the insulating layer at right angles to the slots of the insulating substrate and provided with a plurality of through holes so as to expose said desired portions of the anode lines through the openings of the insulating layer, a transparent insulating substrate disposed in contact
  • the present invention relates to, generally, a llat display panel of the type utilizing DC discharge in a gas; and, more particularly, a flat display panel of the type utilizing subsidiary discharges so as to facilitate the initiation of main discharges.
  • FIG. 1 shows a conventional flat display panel of the type utilizing subsidiary discharges to facilitate th initi ation of main discharges.
  • reference numeral 1 denotes a transparent insulating substrate; 2, anode lines for main discharge; 3, an insulating plate; 4, through holes formed through the insulating plate 3 so as to define main discharge spaces; 5, cathode plates each provided with a row of through holes 6; 7, an insulating substrate provided with a plu rality of slots 8 which define subsidiary discharge spaces and in which are disposed anode lines 9 for subsidiary discharge; and 10, a phosphor material coated on the inner wall of each through hole 4.
  • the initiation of main discharges which occur between the cathode plate and the anode lines 2 through the through holes 4 may be much faciliated when subsidiary discharges occur between the cathode plates 5 and the anode lines 9 for subsidiary discharge. More particularly, the electrons and/or metastable atoms pass through the through holes 6 and flow into the through holes 4, which define the main discharge spaces, by the subsidiary discharges between the cathode plates 5 and the anode lines 9 for subsidiary discharge. The metastable atoms impinge against the side walls of the main discharge spaces of holes 4 so that the secondary electrons are liberated, thus resulting in the increase in electron density in the main discharge spaces.
  • the discharge starting or initiat' ing voltage in the main discharge spaces behind which subsidiary discharges occur may be reduced, and by utilizing this phenomenon, a drive circuit may be made which is simple in construction. That is, the transfer of scanning of the subsidiary discharges may be accom plished by pulse waves in several phases based upon the principle of the well-known step discharge tubes. For instance, when the voltage of the magnitude sufficient to start the main discharge is impressed upon the anode lines extended in the direction of rows as the video signal only when the subsidiary discharge occurs and in synchronism with the scanning line by line of the sub sidiary discharges arrayed in the direction of columns, any desired image may be displayed. According to this driving method, the number of circuits in the direction of columns may be reduced to only a few.
  • One of the defects of the prior art flat display panel with the above constructions is that the fabrication of the insulating plate 0.3mm to 2mm in thickness is provided with a plurality of through holes 4 which separate the main discharge spaces from one another. Owing to this reason. it is extremely difficult to fabricate a largesized flat display panel of, for instance, I X l meter. In other words, the handling of a large-sized thin insulating plate is extremely difficult because of its low mechanical strength.
  • Another object is that when the phosphor material is excited by ultraviolet rays produced by the discharge, the ultraviolet rays tend to be absorbed by the gas of the average distance from one point in the main dis charge spaces to the phosphor material is relatively long, thus resulting in reduced brightness.
  • the radius of the through holes 4 is of the order of (mm so that the possibility of the ultraviolet rays emitted at the center of the main discharge space exciting the phosphor material is very low.
  • a further defect is that it is considerably difficult to cost a phosphor material upon the inner walls of the through holes 4.
  • One of the objects of the present invention is. therc' fore, to provide a large-sized flat display panel which is easy to manufacture.
  • Another object of the present invention is to provide a highly efficient, high brilliance flat display panel.
  • the cathodes may serve as partition walls between the adjacent main discharge spaces so that the insulating plate provides with a plurality of through bores may be eliminated.

  • the phosphor material 10 is coated around each of the main discharge anode electrodes 2.
  • the cathode plates 5 are disposed at right arm glcs to the subsidiary discharge anode line slots 8, and
  • the through holes 13 define the main discharge spaces while the slots 8, the subsidiary discharge spaces.
  • a gas communication passage 14 is formed in each of the cathode plates 5 in opposed relation with and at a right angle to the slot 8 of the insulating substrate 7 so that a pair of main discharge spaces 13 on each side of the slot 8 may be communicated with the slot 8 or subsidiary discharge space. Gas is filled into the main discharge spaces 13, the subsidiary discharge spaces 8.
  • a ceramic or glass plate a few millimeters to one centimeter in thickness is used as the insulating substrate 7 while a glass plate 3mm to one centimeter in thickness, as the transparent insulating substrate 1.
  • the large-sized substrates l and 7 with sufficient mechanical strength may be used.
  • the main discharge spaces 13 except those paircd are separated from one another by the cathode plates 5 so that the prior art insulating plate provided with a plurality of through holes may be eliminated.
  • the through holes 13. 0.2mm to 1mm in diameter, of the cathode plate 5. may be easily formed by suitable etching techniques so that the fabrication of the flat display panels in accordance with the present invention may be much facilitated.
  • the anode lines 2' are spaced apart from each other preferably by a pitch of 0,3 to l.5mm while the depth of the slots 8 is preferably about one-half to threequarters of the pitch.
  • the pressure of the sealed gas or gas mixture depends upon the pitch of the anode lines and the gas or gas mixture. but it is preferably several tens to several hundred torrs.
  • the resonance line or radiation with the highest intensity is when phosphor materials are excited by using ultraviolet rays. but they are very easily absorbed.
  • the resonance line or radiation propagates over 0.3mm in Xe gas at l()() torrsit is subjected to absorption lOO times at an average. Absorption involves the transition between the excited states or levels. If the distance from the point at which the resonance line is emitted to the phosphor material is long, the excitation efficiency of the phosphor material is lowered.
  • the thickness of the cathode plates 5 may be made only about 0.1mm in thickness so that the ultraviolet rays emitted throughout the negative glow range may be efficiently utilized.
  • each subsidiary discharge controls a pair of main discharges intercommuniatcd through the passage 14 of the cathode plate 5 so that the power consumption of the subsidiary dischargesmay be remarkably reduced. with the resulting improvement in the overall efficiency.
  • passages 14 may be formed in the insulating substrate 7. ln this case. the portions of the insulating layer ll corresponding to the passages 14 formed in the insulating substrate 7 must be removed as with the case ofthe anode lines 2'. in other words. it suffices that the passages 14 are formed between the insulating substrate 7 and the cathode plates 5 so as to intercommunicate the through holes 13 and the slots 8. Furthermore, instead of coating the phosphor material 10 upon the insulating layer 11, it may be coated over the inner walls of the through holes [3 or upon the transparent insulating substrate 1.

  • the height of the main discharge electrode 12' extending into the through hole 13 may be arbitrarily selected.
  • the main discharge electrode 12' may be slightly extended beyond the surface of the phosphor material 10.
  • the diffusion loss of the charge particles diffused into the surrounding insulating layer may be reduced so that both the discharge starting and maintaining voltages may be lowered.
  • the discharge distance or gap may be shortened so that the time required for the ions and electrons to travel from one electrode to the other may be considerably redueed with the resulting improvement in rise time of the discharge.
  • FIGS. 6A and 6B The fourth embodiment shown in FIGS. 6A and 6B is substantially similar in construction to the first or third embodiment described hereinbefore except that the subsidiary discharge anode lines 9 are disposed in the slots 8 and are spaced apart from the bottoms thereof by a very small distance,
