Abstract: A planar discharge plasma display device is disclosed, wherein common third signal lines, first signal lines for display discharge, and second signal lines for auxiliary discharge are formed on a rear plate, and barrier ribs for preventing cross-talk between pixels are formed together. Particularly, the signal lines and barrier ribs formed in the same direction constitute an accumulated structure so that the display discharge can be caused fast and stably, and also the occupation area of pixel per unit area is maximized, thereby realizing an image display of higher density.

Abstract: A fluorescent gas-discharge display panel, in which a fluorescent material (8) is excited by a gas discharge therein, contains a gas mixture of neon, argon and xenon as the discharge gas (9). Typically, the argon gas content is more than 5% by partial pressure, and the xenon gas less than 10%. The argon gas content contributes to produce a pure and high peak of green light spectrum and to reduce the orange light spectrum produced by the discharge of the neon gas. Other characteristics, such as operation voltages, brightness, luminous efficacy, and operation life, are kept satisfactory.

Abstract: A self-shift plasma display panel based on the surface discharge is disclosed. This plasma display panel has two electrode groups of shift electrodes and channel electrodes which are positioned so that the two types of electrodes cross at right angles on the same substrate facing a discharge space filled with gas capable of ionization. The shift electrodes are alternately connected to first and second buss at intervals of one electrode, and the channel electrodes are alternately connected to third and fourth buss at intervals of one electrode. The above-mentioned four buss are connected to a four phase alternating voltage source. A discharge spot produced between a shift electrode and a channel electrode is shifted along the channel electrode by means of the four phase alternating voltage applied to the four buss in order.

Abstract: A gas discharge panel includes several pairs of column (X) electrodes arranged on a first substrate and several pairs of row (Y) electrodes arranged on a second substrate, the column and row electrodes being orthogonally oriented and in spaced, opposed relation to define therebetween a gap filled with an ionizable gas. In a first driving configuration, a corresponding electrode of each pair of (X) electrodes is selectively driven by an (X) address driver and similarly a corresponding one of each of the (Y) electrode pairs is selectively driven by a (Y) address driver. The other electrode of each of the (X) and (Y) electrode pairs then is connected in common to respective (X) and (Y) sustain voltage driver terminals. In a further embodiment, each of the (X) and (Y) electrode pairs is arranged in corresponding groups of electrode pairs, each group including a common number of such pairs. First electrodes of each pair of each group are connected to a common output terminal of an address and sustain voltage driver; thus, plural address and sustain voltage driver outputs corresponding to the plural groups are employed for each of the (X) and (Y) electrode pairs. The second electrodes of corresponding pairs of the plural groups are connected to respectively corresponding, further common output terminals of address and sustain voltage drivers; thus, a plurality of further common terminals corresponding to the number of electrode pairs in each group are provided, as to each of the (X) and (Y) electrodes. The panel as thus configured affords decoding of addressing signals applied to the common terminals by means of plasma coupling within the panel whereby the discharge point or cell defined by a desired electrode of each of the column and the row electrode pairs can be addressed selectively. A further embodiment provides shifting of the display to successive positions in either the (X) or (Y) directions.

Abstract: 1411804 Gas discharge display panels FUJITSU Ltd 18 Oct 1972 [18 Oct 1971] 48090/72 Heading H1D A gas discharge display device having first and second main arrays of electrodes formed respectively on opposed walls of the discharge chamber, in a mutually crossed relationship, and with both arrays separated from the gas filling by dielectric films, is provided also with an auxiliary array of electrodes connected in common and arranged at locations which alternate with the electrodes of one of the main arrays, whereby the form of the discharge at any crossing-point of the main arrays may be influenced, to reduce the probability of mis-shift during operation, e.g. application to the auxiliary array of a voltage of the same or opposite sense to that applied to a conductor of the main array respectively increases or decreases the area of the discharge (Figs. 4, 5, 8A, and 9A, not shown). Both main electrode arrays 2 may be provided with an auxiliary array 5 which may be separated from its main array by an insulating layer 3 and which may, as shown, be in contact with the gaseous filling 4, or be separated therefrom by a further insulating film (Fig. 2, not shown). Alternatively, the main and auxiliary arrays may be coplanar (Fig. 3, not shown). The device is filled with a neon/ nitrogen mixture. Circuitry for a self-shift panel is described (Figs. 10 and 11, not shown).

Abstract: 1407623 Gas discharge display panels FUJITSU Ltd 10 Aug 1972 [10 Aug 1971] 35832/72 Heading H1D [Also in Division G4] In a gas discharge panel including a conductor array insulated from the gas every third electrode is interconnected to form 3 groups. A display panel comprises a pair of glass plates supporting Au, X, Y conductor arrays covered with glass and is filled with Ne or N 2 and A. The Y array comprises 7 conductors l 1 ... l 7 extending from the second X conductor b 1 . Seven write conductors # 1 ... # 7 extend in the Y direction but spaced from the Y conductors, to the first X conductor a 1 . Leads are taken to both sides of the panel, crossing leads being separated by dielectric 11. The X conductors are sufficiently close so that a discharge in one site produces appreciable ionisation in adjacent sites thereby reducing the ignition voltage at the adjacent site. The Y conductors are all earthed and overlapping sustain pulses are applied sequentially to the three groups of X conductors. A write pulse is applied to a conductor # which with the sustain pulse produces a discharge. A sustain pulse on adjacent conductor b 1 is then sufficient to produce a discharge at the interesction of b 1 and the Y conductor adjacent to # 1 ; subsequent pulses move the discharge across the panel. Sites are not reignited because ionization from adjacent discharges neutralizes wall charges; alternatively erase pulses may be applied. The direction of movement can be reversed by altering the sequence in which pulses are applied, thereby removing incorrect data. Driving circuitry includes a pulse generator 22 connected via gates 23, G and amplifier 24, M to the conductors; a diode matrix 30 generating a character pattern and differentiation circuits D; a keyboard 21 and a register 31. A resistive layer of Pb may be provided on one or both dielectric layers over and parallel to the Y conductors to improve the shift action and the dispersal of wall charges. The Y electrodes may be replaced by an array similar to the X array at least over part of the panel to enable discharges to be moved in the X and Y directions. To enable a pattern to be superposed on an existing display subelectrodes 1 1b , l 1c ..., l 2 b, l 2e ... are added adjacent electrodes l 1 l 2 ... (Fig. 16) and electrodes b, c are brought closer to electrodes a at their intersections with the sub-electrodes. A pattern generated on electrodes l 1 l 2 ... is shifted to the sub-electrodes and stored on subelectrodes l 2b l 2c .... When further discharges are generated the stored pattern is unaffected as the distance between adjacent electrodes b, c is too great to produce appreciable ionisation. Another embodiment (Fig. 11A) comprises a substrate 41 supporting shift conductors a, b, c and write conductors 42, a cover 46 containing grooves 45 and a dielectric layer 44 separating the electrodes from the gas space. The shift conductors are interconnected in three groups and sustain pulses applied as before. A discharge is produced first between write conductors and a first shift conductor a 1 , then between adjacent shift conductors. The output of the last X conductor can be read out by photoelectric elements or recorded via light guides on to photosensitive paper.
