Definitions
- the invention relates to a method for addressing and controlling a plasma display panel.
- Addressing and controlling a plasma display panel of this type generally comprises the following steps:
- the addressing discharge extends essentially perpendicular to the slabs, in the space, filled with discharge gas, which separates the slabs; the maintenance discharges extend, on the contrary, essentially parallel to the slabs, along the front slab.
- the instantaneous frequency of the holding pulses is generally of the order of 100 to 300 kHz and conditions the brightness of the panel; the holding is qualified as “positive” if the two electrodes of the pair always have a positive or zero potential with respect to the addressing electrodes, “negative” in the opposite case, “bipolar” in the case where this potential is alternately positive and negative (the holding signals of the electrodes of the same pair are then shifted by half a phase).
- the addressing pulses can be grouped by groups of lines and are then also very close to one another.
- the document JP 10-171399 proposes to use, in addition, very high frequency pulses, much greater than 10 MHz.
- the addressing and control of the coplanar plasma display panel then comprise the following steps:
- the purpose of applying a very high frequency signal is, once the charges have formed between the electrodes after a conventional sustaining discharge, to prevent the ionic charges from reaching the cathode , and to obtain the vibration of the ionic charges between the electrodes as shown diagrammatically in FIG. 4-VII of this document; with reference to FIG. 5, this document teaches: that it is necessary to start applying the signal RF 100 before the conventional sustaining discharge corresponding to the pulse 101 has led to the complete reversal of the charges on the dielectric layer which covers the electrodes; thus, the time t d which separates the pulse edge 101 from the first edge of the RF signals should be much less than the cumulative time of the sustaining discharge and of the complete charge reversal;
- the half-period t w of the RF 100 signal should be short enough so that the ionic charges do not have time to reach the cathode in half a period; this condition generally leads to very high frequencies which are difficult to implement.
- the above conditions are as follows: t ⁇ 1 ⁇ s approximately; t w ⁇ 0.1 ⁇ s approximately, which corresponds to frequencies above 20 MHz.
- each holding step comprises a succession of conventional holding discharges and stabilized discharges: - a first discharge, generated by a conventional holding pulse, intended to create ionic charges in the activated zone,
- a stabilized discharge generated by a train of high frequency pulses adapted to stabilize the ionic charges created in the activated zone.
- the sustaining discharge is used to activate or "turn on" the stabilized discharge.
- a plasma panel akin to a coplanar panel, comprising, for each discharge space, an anode 40 and an auxiliary electrode 50 which are coplanar and carried by the same slab, and a cathode 60 carried by the other slab; unlike conventional coplanar panels which have a lasting memory effect, no dielectric layer separates the electrodes, so that it only produces a short-term pseudo-memory effect, ie a memory effect of conditioning by the previous discharge or by an adjacent source of primary particles; in the control of such a panel, according to this document, pulses of sufficient amplitude are applied between the anode and the cathode to obtain a succession of discharges; during the application of these pulses comparable to holding pulses, higher frequency pulses are applied between the coplanar electrodes 40 and 50 to disturb the movements of the ions and cause them to diffuse between the electrodes (column 2, lines 20 -21 and 40-41; column 3, lines 38-39 and 57-58); this disturbance only leads to the elongation of the path of the
- JP2000-173482 describe plasma panel structures specially adapted for obtaining stabilized discharges using trains of high frequency pulses; but the use of specific panel structures poses other cost problems.
- the object of the invention is to avoid the abovementioned drawbacks, by proposing to use a conventional coplanar panel in a manner different from that proposed in the document JP 10-171399, so as to be able to stabilize the discharges at lower frequencies. , without having to increase the voltage required for lighting stabilized discharges.
- the subject of the invention is a method for controlling a plasma display panel of the coplanar type comprising:
- the first screen is a "back” screen and the second screen is a "front” screen oriented towards the observer of the images to be viewed;
- the electrode crossing zones form the panel discharge cells, which can be controlled, activated or not, independently of each other, depending on the voltage pulses applied to the electrodes.
- the holding pulses are applied between electrodes of the first slab and electrodes of the second slab; preferably, the tiles are chosen to be spaced so as to be able to use holding voltages and conventional electronic components; the spacing is then generally between 100 and 150 ⁇ m; if each slab is provided with a dielectric layer with a thickness of 40 ⁇ m, the distance separating the network of electrodes of the first slab from the network of pairs of electrodes of the second slab is then between 180 and 230 ⁇ m; a distance as small as 90 ⁇ m could, ultimately, be considered between these electrodes;
- the distance separating the electrodes of a pair of the second slab is greater than the distance separating the electrode of the first slab and the electrode of the second slab between which the holding pulses are applied; thus, the gap between the coplanar electrodes, or distance separating the paired electrodes, is much higher than in the prior art so as to be able to stabilize the discharges using trains of pulses of lower frequency than in the prior art; a gap greater than 500 ⁇ m can even be envisaged.
- the invention may also have one or more of the following characteristics:
- the second network of pairs of electrodes is covered with a dielectric layer; the classic memory effect of coplanar panels is thus obtained.
- said first slab is covered with a thin layer of protection and secondary electron emission and provided with layers of phosphors positioned to absorb ultraviolet radiation from the discharges and to emit visible radiation through the slab oriented towards the 'front of said panel and these layers have savings at the crossover areas of the electrodes so as to discover at this savings the surface of said underlying thin protective layer.
- the rear panel and, where appropriate, the walls of the barriers which separate these zones, are provided with phosphors of different colors d 'emission, red, green and blue; unlike the prior art, the maintenance discharges are initiated between the front panel and the rear panel; to facilitate priming at the level of the rear slab, the surface of the slab should be made of a material capable of emitting secondary electrons under ionic impact, such as magnesia (MgO), at the foot of the discharges; for this purpose, the phosphor layer is removed in these zones so as to reveal the underlying thin layer based on MgO.
- MgO magnesia
- the distance between the electrode of the first slab and the electrode of the second slab between which the pulses are applied hold is less than 250 ⁇ m; in addition, the distance separating the electrodes of the same pair at the crossings is then preferably greater than or equal to 250 ⁇ m; preferably, the frequency of pulse stabilization pulse trains is less than 150 MHz, or even less than or equal to 60 MHz.
- the subject of the invention is also a plasma display panel of the coplanar type intended to apply the control method according to the invention, comprising:
- a second slab parallel to the first, provided with at least a second network of pairs of electrodes, the general direction of which is approximately orthogonal to that of the electrodes of the first network, the electrodes of each pair providing discharge zones between them positioned at the intersections of the electrodes of the first array and the pairs of electrodes of the second array, characterized in that, at each discharge zone, the distance separating the electrodes from a pair is greater than the distance separating the electrode from the first plate crossing said zone and any one of the electrodes of said pair (X, Y).
- the distance between the first array of electrodes and the second array of pairs of electrodes is less than 250 ⁇ m and the distance separating the electrodes of the same pair at the crossings is greater than or equal to 250 ⁇ m;
- the second network of pairs of electrodes is covered with a dielectric layer, itself generally covered with a protective layer; - said first slab is covered with a thin layer of protection and secondary electron emission and provided with layers of phosphors positioned to absorb ultraviolet radiation from the discharges and to emit visible radiation through the slab oriented towards the 'front of said panel and these layers have savings at the crossover areas of the electrodes so as to discover at this savings the surface of said underlying thin protective layer.
- FIGS. 1 and 2 schematically represent an embodiment of a set of three adjacent discharge zones of a coplanar display panel which can be advantageously used for the implementation of the invention
- FIG. 1 in view of above
- Figure 2 in cross section
- - Figure 3 shows a longitudinal sectional view of a discharge zone of the assembly shown in Figures 1 and 2, illustrating the spread of discharges (arrows) according to one embodiment of the invention
- FIG. 4 represents, according to one embodiment of the invention, a timing diagram of the voltages applied to the different electrodes of the panel shown in FIGS. 1, 2 and 3.
- the coplanar panel used for the implementation of the invention comprises:
- a rear panel (not shown) with an array of electrodes A, coated with a dielectric layer 1, with an array of barriers 21, 22;
- a front panel (not shown) provided with an array of pairs of electrodes X, Y, coated with a dielectric layer 3;
- the general direction of the electrodes X, Y of the front panel is orthogonal to that of the electrodes A of the rear panel.
- the dielectric layers 1, 3 are themselves coated with a very thin layer of protection and of secondary electronic emission, here based on MgO (not shown).
- the barrier network is formed here of walls 21 extending parallel to the electrodes A of the rear panel and of walls 22 extending parallel to the electrodes X, Y of the front panel, so as to delimit discharge zones 4R, 4G , 4B at the intersections of the electrodes A on the one hand, and of the paired electrodes X and Y on the other hand.
- the tops of the rear slab barneres support the front slab.
- the walls of the barriers and the dielectric layer 1 of the rear panel are covered with layers of phosphors 5R, 5G, 5B, capable of emitting respectively in red, green and blue, under the excitation of ultraviolet radiation from discharges. located respectively in zones 4R, 4G, 4B; the set of three adjacent discharge zones represented in FIGS. 1 and 2 therefore corresponds to an image element or pixel of the image display panel for implementing the invention.
- the electrodes A of the rear plate comprise conductive bus 61 extending under the barriers over the entire height of the panel, which is provided, at each discharge zone, a branch 62 projecting; each derivation 62 of a given area 4R, 4G or 4B is placed facing the electrode X of the pair X, Y which crosses said area, and extends towards the middle of this area; facing the free end of each lead 62 of the electrode X, the dielectric layer 1 is devoid of phosphors, so as to form a sparing 7 in the layers of phosphors 5R, 5G, 5B, to be discovered at this level.
- the panel comprises an electrode A per column of picture elements.
- the paired electrodes X, Y extend over the entire width of the panel; the panel has one pair X, Y per line of picture elements; according to an alternative embodiment, an electrode X can be common to two adjacent lines of picture elements, as described in document US 5162701
- the distance between the pairs of electrodes X, Y at each picture element is greater than the distance between the network of electrodes A of the rear panel and that of pairs electrodes X, Y of the front panel, that is to say greater than the sum of the distance between the panels and the thickness of the layers applied to these networks; details are given below.
- the electrodes are connected to a voltage supply system for the column electrodes A of the first network and paired electrodes X, Y of the second network; a supply system of this type is known in itself and will not be described here; in a conventional manner, using this system, images are displayed on the panel, by scanning this panel line by line, or group of lines by group of lines; in a conventional manner, each scan is itself subdivided into several sub-scans, which make it possible to obtain the desired number of gray levels; with reference to FIGS. 3 and 4, each underscan comprises at least the following steps:
- this pulse train is obtained here by applying a radio frequency signal TSY to the electrode Y; as in document JP 10-171399, the time interval which elapses between the application of a holding pulse, SHX OR SHA, and the start of the application of the train of pulses T S Y, must be less than the time required to reverse the electrical charges resulting from this sustaining discharge; preferably, unlike the process described in document JP 10-171399 where the high frequency pulse trains are interrupted before each holding pulse, the high frequency pulse train is applied here without interruption, until the end of the holding period relative to the subscan concerned; this arrangement makes it possible to stabilize the maximum of ions generated by the sustaining discharges, to further improve the light efficiency of the panel, and also to improve the electrical efficiency since this thus limits
- the embodiment of the invention which has just been described results in a succession of discharges DA, then the series DH, DS, as shown in the last timing diagram of FIG. 4; it can therefore be seen that the holding discharges DA serve to ignite or reinforce the stabilized discharges Ds. Because the savings 7 release a protective layer surface based on MgO directly in contact with the discharge zones, the holding voltage necessary for obtaining a discharge retains a conventional value; in addition, the presence of these savings makes it possible to limit the damage to the layers of phosphors.
- the sustaining discharges D H and the stabilized discharges Ds do not extend between the same electrodes (X and A for the first, X and Y for the second), one can independently choose:
- this distance is generally between 180 and 230 ⁇ m; lower values can be considered;
- a sufficiently high distance between the X and Y electrodes to be able to use lower frequencies to stabilize the discharges is preferably greater than or equal to 250 ⁇ m; a distance of between 500 ⁇ m and 1000 ⁇ m can also be envisaged in order to further lower the stabilization frequencies of the discharges; a high value of the "gap" between the coplanar electrodes advantageously makes it possible to avoid the use of transparent conductive materials for these electrodes, since such a gap offers sufficient optical opening through the front panel; this results in narrow and opaque coplanar electrodes, therefore economical, as shown in FIG. 1.
- the frequency of the holding pulses SHX, SHA is generally between 1 kHz and 50 kHz.
- the frequency of the holding pulses SHX, SHA is generally between 1 kHz and 50 kHz.
- coplanar panel other types can be used to implement the invention, such as panels comprising a greater number of arrays of electrodes, panels where the line electrodes are common to two lines adjacent discharge zones, panels where the discharge zones are staggered as in document US 5825128 (FUJI), panels where the pairs of coplanar electrodes are located on the rear face as described in document EP 945890 ( THOMSON).
