Abstract: A plasma display panel in which two transparent base plates are assembled together to define a discharge gas space therebetween. On each transparent base plate, a plurality of strip-like main electrodes are provided and a dielectric layer is formed to cover them and, further, third electrodes are each provided between adjacent ones of the main electrodes. The two transparent base plates are assembled together in opposing relation to each other in such a manner that their main electrodes and third electrodes are disposed substantially perpendicuar to each other in the form of a matrix. By impressing a voltage to selected ones of the main electrodes of the both transparent base plates, a discharge spot is produced at their intersecting point to provide a display. The discharge spot becomes enlarged or reduced or extends in a certain direction according to the polarity of a voltage impressed between the third electrodes of both transparent base plates and to the selection of the third electrodes to be supplied with the voltage. The discharge spot can be shifted in either direction of the row and column of the matrix.

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: 1433665 Gas discharge display panels MITSUBISHI DENKI KK 27 Feb 1974 [27 Feb 1973] 8965/74 Heading H1D A plasma display panel apparatus comprises a first laminar array of substantially parallel elongate main strip electrodes 12, a second laminar array of substantially parallel elongate main strip electrodes 18, the said arrays being disposed face to face with a gas-containing discharge gap 24 therebetween and with the electrodes of one array crossed with respect to those of the other array, at least one said array being provided with auxiliary elongate strip electrodes 50 or 52 respectively adjacent to and parallel to main electrodes of the array, circuitry 36, 40 for applying to all the auxiliary electrodes a sustaining voltage for producing across the discharge gap voltage pulses of alternating polarity, electrical insulation between one array and the gas, light-transmitting electrical insulation between the other array and the gas, and circuitry for applying selectively to main electrodes of both arrays discharge-initiating or discharge-quenching voltage pulses Px, Py or Qx, Qy. The sustaining voltages are of insufficient amplitude to initiate a discharge but simultaneous application of initiating pulses Px and Py to selected main electrodes 12 and 18 results in a discharge at the cross-point 56 of the selected electrodes, together with the establishment of a region of wall charges 58. Subsequent sustaining pulses in conjunction with the reversing wall charges produce and extinguish discharges in turn at cross-points 62, 60, 64 and back to 56. This continues until extinguishing pulses Qx and Qy applied to the selected main electrodes reduce the wall charges to zero so that subsequent sustaining pulses are unable to produce a discharge. In an alternative embodiment (Figs. 7 and 9, not shown) one array of auxiliary electrodes is omitted, the operations being then effected by applying a train of bipolar pulses to the remaining auxiliary electrode array. The gas filling may be neon plus a small amount of argon or nitrogen.

Abstract: 1421916 Multi-gap cold-cathode tubes; gas discharge display panels FUJITSU Ltd 15 Dec 1972 [15 Dec 1971] 58184/72 Heading HID [Also in Divisions H3-H5] Gas discharge apparatus comprises first support means 1 supporting on a face thereof a first electrode X3 and a control electrode X1 extending parallel to one another, which arrangement is covered by a first dielectric layer 2, and second support means 3 supporting, on a face thereof that confronts the said face of the first support means, a second electrode Y extending transversely with respect to the first and control electrodes, in crossing relationship thereto, and covered with a second dielectric layer 4, there being a discharge gas confined in a discharge space 5 between the confronting faces of the first and second support means, and voltage supply means connected electrically to the electrodes and operable to establish between the first and second electrodes X3 and Y a working voltage such that a discharge can thereby be produced between those electrodes in dependence upon electrical discharge control conditions (applied control voltage or actual discharge) established by the voltage supply means between the control and second electrodes X1 and Y. A second control electrode X2 may be provided. The electrode arrangement may be operated as a logic AND, OR, NOT, NOR or NAND circuit or as a flip-flop circuit (see Divisions H3-H5) in either a discharge or non- discharge mode. Coupling between adjacent gaps by flow of wall charges may be assisted by providing a resistance film on dielectric layer 4 covering electrode Y. A plurality of the above-described electrode arrangements may be combined to form a plasma display panel (Fig. 2) in which electrodes A, B and C correspond to electrodes X1, X2 and X3 respectively. The electrodes are connected in groups as shown to enable n x m discharge gaps to be addressed from n + m terminals. The number of gaps addressed from the same number of terminals can be doubled by using an additional group of C electrodes (shown dotted). In a further embodiment (Fig. 5, not shown) the Y electrodes are connected in the same way as the A and B electrodes in Fig. 2. The gas filling may be 95 % Ne and 5% N 2

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: 1357562 Gas discharge display panels FUJITSU Ltd 10 Aug 1971 [10 Aug 1970] 37582/71 Heading H1D Display apparatus comprises a gas discharge panel with insulating walls 21, 22 carrying electrodes 19, 20 and crossed conductor arrays 16, 17 and circuitry connected to the arrays operable to produce cyclotron resonance of electrons to establish a glow discharge at any selected conductor intersection, by producing at that intersection crossed magnetic and microwave electric fields. The panel includes continuous electrodes 19, 20 insulating plates 13, 14 and ferromagnetic films 18 on which the conductors 16, 17 are mounted. A microwave signal is applied across electrodes 19, 20 and a potential is applied to selected conductors. The potential is such that the resulting current and magnetic field produce an electron rotational frequency equal to the frequency of the microwave signal. Under these conditions cyclatron resonance occurs and the microwave power required to initiate a discharge is 1/100 that required if the magnetic field has other values, hence a discharge occurs at selected intersections. The variation of power required with field is very great hence the field due to current in one conductor alone is insufficient to produce a discharge. Moreover a discharge remains localized since charged particles are not given any net movement parallel to the plates 13, 14. The discharge can be maintained with the same microwave power but a lower field hence lower sustaining currents can be applied thereby producing a memory effect. The discharge is erased by further reducing the field. Sustaining D.C. current can be applied to all of the conductors and discharges produced and erased by positive and negative pulses. In other embodiments the sheet electrode is replaced by a strip electrode extending in zig-zag or serpentine fashion over plate 13; the electrodes 16, 17 are on the outside of plates 13, 14 and electrodes 19, 20 on the inside, the latter may be replaced by crossed conductor arrays.

Abstract: An addressable gaseous discharge device utilized for information display comprises a pair of spaced parallel oppositely positioned insulating walls forming between them a gas cell filled with ionizable gas. At least one of the insulating walls is transparent. The perimeters of the insulating walls are hermetically sealed. Field electrodes mounted on the insulating walls apply a microwave electric field to the gas cell and field electrodes mounted on the insulating walls partly and selectively apply a magnetic field in a direction crossing the microwave electric field. A glow discharge occurs in a selected part of the gas cell when the two applied fields meet the condition of cyclotron resonance of an electron.

Abstract: A plasma display panel in which address characteristics can be stabilized. A front substrate (1) and a back substrate (2) are disposed oppositely to form a discharge space (3) which is then sectioned by a partition wall (11) to form a priming discharge cell (16) and a main discharge cell (12). Since a priming electrode (15) is formed on a dielectric layer (17) in the priming discharge cell (16), insulation is ensured between a data electrode (10) and the priming electrode (15) and priming discharge can be generated surely before main discharge.
