Definitions
- the invention relates to a plasma display panel comprising:
- a first slab 1 comprising at least a first array of electrodes Y (not shown) coated with a dielectric layer 3 and with a protective and secondary electron emission layer 4,
- a second slab 2 providing with the first a space containing a discharge gas, divided into a two-dimensional matrix of discharge zones 5, each discharge zone 5 being positioned between the electrodes of the first network and those of the second network and having walls partially covered with a layer 6 of a phosphor adapted to emit visible light under the excitation of the radiation of a discharge in this area, the first slab comprising means for re-diffusing the radiation of discharges towards the phosphors of the corresponding zones, here a diffusion layer 9.
- the second network of electrodes is generally placed on the first slab, so that, in operation, most of the discharges arise between two electrodes of the same slab and are described as coplanar; neither of the two arrays of coplanar electrodes Y, Y 'is shown in FIG. 1, because it represents a section made in a plane passing between these electrodes; generally, the second panel comprises a third array of X electrodes, which is used for addressing or activating the discharge zones of the panel, before the so-called maintenance periods.
- the dielectric layer 3 is intended to obtain a memory effect, so as to be able, after activation of a discharge zone, to maintain a succession of discharges by application of adapted voltage pulses between the electrodes of the first network Y and those of the second network Y '.
- the protective and secondary electron emission layer 4 serves to protect the dielectric layer from the bombardment of the ions originating from the plasma of the discharges; it is also capable of emitting electrons under the effect of this ion bombardment, so as to stabilize the operation
- the first screen 1 which is generally transparent to the radiation emitted by the phosphors and which then forms the screen before viewing images;
- the second slab is therefore the rear slab, which is generally covered with phosphors at each of the discharge zones.
- the discharge zones of the panel are, generally and at least in part, delimited by barriers 7, which form walls for the discharge zones 5 and generally serve as means for spacing the slabs; in each discharge zone, the phosphors 6 are generally applied both to the rear slab and to the sides of the barriers.
- the plasma discharges 8 emit ultraviolet radiation, shown in dotted lines in FIG. 1.
- a first part of this ultraviolet radiation is emitted in the direction of the rear panel 2 and of the sides of the barriers 7 and is therefore directly absorbed by the phosphors 6 deposited at this location; the phosphors are then excited and emit visible radiation which passes through the front panel 2 and thus participates in the formation of the image to be displayed: the visible radiation is shown in solid lines in the figure.
- a second part of this ultraviolet radiation is emitted in the direction of the front panel 1; thanks to the diffusion means with which the front panel is fitted and which will be described below, this radiation is re-transmitted, at least partially, in the space between the panels, in particular towards the phosphors 6 to be converted into visible radiation like the first part of the ultraviolet radiation. It can therefore be seen that the diffusion means with which the front panel is provided makes it possible to convert a greater part of the radiation emitted by the discharges and to significantly increase the light output of the panel.
- this layer is preferably interposed between the dielectric layer and the protection and secondary electron emission layer; - Or, as shown in Figure 1, using a diffusion layer 9, deposited on the protective layer and having a particle size suitable for obtaining the diffusion effect in the range of wavelengths corresponding to ultraviolet radiation.
- the subject of the invention is a panel intended to be part of a plasma panel and comprising at least a first network of electrodes coated with a dielectric layer and with a layer for protecting and emitting secondary electrons, said plasma panel comprising at least a second array of electrodes and a second panel providing with the first panel a space containing a gas of discharge, the electrodes of the first network and those of the second network being arranged to form between them and between the slabs of the discharge zones and the walls of these zones being partially covered with a layer of phosphor suitable for emitting visible light under the excitation of the radiation of discharges emitted between the electrodes in these zones, characterized in that the interface between the dielectric layer and the layer of protection and emission of secondary electrons is structured so as to present an average roughness included in the wavelength range of said discharge radiation and / or of the light emitted by said phosphor, in particular of In the case where this luminophore is a luminophore emitting in the ultraviolet.
- the invention also relates to a panel intended to form part of a plasma panel and comprising at least one network of electrodes coated with a dielectric layer and with a layer of protection and emission of secondary electrons characterized in that the interface between the dielectric layer and the protective layer is structured so as to have an average roughness of between 130 nm and 400 nm, preferably between 130 and 200 nm.
- the slab according to the invention comprises means for re-diffusing the radiation from the discharges towards the phosphors; in general this slab is not coated with phosphors, although this provision is not excluded.
- the average roughness of the structured interface according to the invention can be evaluated using a conventional roughness meter with an electromagnetic probe.
- the protective and secondary electron emission layer being very thin, it generally has the same structure as that of the structured interface according to the invention, so that one can then measure the roughness of the interface on the protective layer surface.
- the wavelength range of the discharges radiation corresponds to the spectral range comprising more than 90% of the energy emitted by the discharges.
- the discharge gas is based on a mixture of Neon and Xenon and the discharges in the panel emit ultraviolet radiation, having two main emission peaks, one at 145 nm, the other at 175 nm; thus, preferably, the range of wavelengths of the radiation from the discharges being included in the ultraviolet, the average roughness of said interface is between 130 and 200 nm.
- the protective and secondary electron emission layer is based on oxide of alkaline earth elements, in particular based on magnesia (MgO).
- MgO magnesia
- the dielectric layer is based on vitreous inorganic material.
- the invention also relates to a plasma panel comprising a slab according to the invention and a second slab providing with the first slab a space containing a discharge gas, also comprising a second network of electrodes, the electrodes of the first network and those of the second network being arranged to provide between them and between the slabs of the discharge zones and the walls of these zones being partially covered with a layer of phosphor suitable for emitting visible light under the excitation of the radiation of discharges emitted between the electrodes in these zones.
- the first tile according to the invention is the front tile of the panel; “slab before” is understood to mean that which is situated on the side of the observer of the images displayed by the panel; the electrodes placed on this slab are generally transparent; because it is structured according to the invention to re-diffuse only the radiation emitted by the discharges between the slabs, the interface between the dielectric layer and the protective layer does not absorb or very weakly the visible light emitted by the phosphors; this front panel is therefore advantageously transparent to the visible light emitted by the phosphors; it is all the more transparent to this light as the interfaces or dioptres to be crossed are fewer than in the panels of the prior art also comprising means for re-diffusion or reflection of the radiation from the discharges.
- the subject of the invention is also a method capable of being used for the manufacture of a plasma panel slab according to the invention comprising the deposition of a dielectric layer on the at least one network of electrodes of this slab and the deposition of a protective and secondary electron emission layer on the dielectric layer, characterized in that, before the deposition of said protective layer but after the deposition of the dielectric layer, an operation is carried out abrasion of the surface of the dielectric layer adapted so that the average roughness of this surface is within the range of the wavelengths of the radiation of the discharges in the plasma panel, in particular so that it is between 130 and 400 nm , preferably between 130 and 200 nm.
- Such a process is particularly simple and economical; it is preferably applicable in the case where the dielectric layer is based on vitreous inorganic material, ie enamel; such an enamel layer is generally obtained by depositing a layer based on a dielectric enamel frit followed by baking under conditions suitable for obtaining a dense layer having a smooth surface; the abrasion operation of this surface is then carried out just after the step of firing the enamel; this abrasion operation modifies the roughness of the surface of the enamel; we then deposit a in a conventional manner the protective layer, generally based on MgO; as this protective layer is very thin, the layer obtained generally has the same roughness as the surface of the enamel layer.
- the protective layer generally based on MgO
- the abrasion operation of the surface of the dielectric layer is carried out by rubbing a plastic material encrusted with abrasive powder against this surface; this is a commonly used method for polishing or lapping glass surfaces or metallographic samples; the plastic material is preferably a polishing felt, for example based on rigid polyurethane foam, having open pores on the surface, capable of containing or retaining grains of abrasive powder; it is also possible to use plastic pastes incorporating the abrasive powder.
- the diameter of the grains of the abrasive powder is preferably between 0.2 and 2 ⁇ m; in practice, this is the size of the abrasive grains suitable for obtaining a dielectric layer surface having an average roughness of between 130 and 200 nm.
- the abrasion operation is carried out in a liquid medium free of water or dry; a special felt is then used encrusted with grains of abrasion powder.
- FIG. 1, already described, is a schematic sectional representation of a plasma panel cell of the prior art
- FIG. 2 illustrates, according to the same representation, a preferred embodiment of the invention applied to the same type of cell.
- identical references are used for the elements which perform the same functions.
- FIG. 2 we will begin by describing a preferred example of a method for obtaining a plasma panel with high light output according to the invention, in the case where this panel is of the alternative type with memory effect; this panel comprises a transparent front panel Y with pairs of coplanar electrodes and a rear panel 2.
- this panel comprises a transparent front panel Y with pairs of coplanar electrodes and a rear panel 2.
- each electrode of the first network is adjacent to an electrode of the second network; each pair of electrodes thus formed then corresponds to a line of picture elements of the display panel; each electrode is for example formed of an opaque and narrow bus for distributing the discharge current and of a transparent conductive strip, for example of ITO ("Indium Tin Oxide" in English) deposited along the bus and in contact with this one ; in this case, electrodes of the same pair face one side of their respective transparent strip.
- ITO Indium Tin Oxide
- a paste based on a sintered dielectric enamel is then prepared which is deposited on the electrode networks in a layer of homogeneous thickness over the entire active surface of the slab; according to a variant, it is possible to cover only the electrodes of the networks Y, Y '; in addition to this enamel frit, this paste contains an organic binder based on a polymer and, generally, a solvent for this binder; after deposition and drying to evaporate the solvent, crosslinking of the organic binder if necessary, the enamel layer is fired to remove the organic binder from the layer and vitrify the enamel so as to obtain a homogeneous layer 3 ' dielectric enamel; after curing, the layer obtained has a smooth and flat surface, which, as it stands, would allow radiation from the landfills to pass; the thickness of the dielectric layer is generally between 10 and 50 ⁇ m.
- the next step is specific to the invention; it consists in modifying the surface condition of the dielectric layer to give this surface the capacity to diffuse the ultraviolet radiation that the discharges will emit, in particular between the electrodes of the networks Y, Y ', in the panel in operation.
- an abrasion operation is carried out on this surface so as to obtain a dielectric surface, not as smooth as before, but having an average roughness included in the range of wavelengths of the radiation which will be emitted by the discharges. in the panel in operation; conventionally, this field is that of ultraviolet radiation and this operation is carried out so as to give the dielectric surface an average roughness of between 130 and 200 nm; this average roughness is for example evaluated using a roughness meter with an electromagnetic head, such as a DEKTAK brand device.
- numerous known methods can be used, such as for example mechanical lapping using a very fine abrasive powder.
- the surface of the enamel lends itself well to a mechanical lapping operation using a very fine abrasive; preferably abrasives with grain sizes between 0.2 ⁇ m and 2 ⁇ m which are commercially available, either in paste (diamond, alumina, carborundum) or on felt for dry polishing; more precisely, one can for example operate according to one of the following methods: running in liquid medium with a diamond paste, using a lubricant, preferably neutral and chemically inactive with respect to the enamel layer; preferably using a heavy alcohol, for example of the isopropanol type, compatible with the paste enclosing the diamond-based abrasive powder; the use of water is advantageously avoided so as to better guarantee the properties of the protective layer based on MgO to be deposited on the lapped surface; dry running using a special felt enclosing the abrasive powder, for example of the “sandpaper” type; thus avoiding using water, the properties of the MgO-based protective layer
- abrasion methods such as spraying with a carrier gas of abrasive powder on the surface (or "sandblasting"); chemical abrasion methods, electro-erosion methods, mechanical-chemical methods well known to those skilled in the art of surface treatments can also be used.
- the dielectric layer now has a “structured” surface:
- a protection and secondary electron emission layer 4 ′ is deposited in a manner known per se, here based on MgO; one proceeds for example by vacuum evaporation; the thickness of the layer obtained is generally between 0.5 and 1.5 ⁇ m.
- the layer obtained is very thin, it is found that the roughness and the structuring of the surface of the dielectric layer is transferred to the external surface of the layer of protection and emission of secondary electrons.
- the structure of the surface of the dielectric layer 3 ′ at the interface with the protective layer 4 ′ is of the “spatial noise” type, like, moreover, the structuring of the protective layer itself; such a structuring is different from that of the diffusion layers described in the document EP 1085554 already cited, obtained by precipitation in an aqueous route.
- the front panel Y according to the invention is capable of backscattering the ultraviolet radiation and letting the visible radiation pass, by virtue of the structuring of the interface between the dielectric layer 3 'and the protective layer 4', adapted to impart roughness average in the range of the wavelengths of the radiation from the discharges, in particular between 130 and 200 nm; such re-diffusion means are much more economical and effective than those of the prior art; in fact, such roughness can be obtained by a simple abrasion operation; moreover, owing to the absence of an operation for depositing a specific additional layer to reflect or redistribute UV rays, the slab obtained has a higher mechanical resistance.
- a network of barriers 7 adapted to delimit discharge zones and so that they are, after assembly of the slabs, positioned at the intersection of the electrodes of the network X and pairs of tangled electrodes of the networks Y, Y 'of the first slab , - layers of phosphors 6 deposited on the walls of the discharge zones thus delimited, that is to say both at the bottom of these zones in contact with the dielectric layer 13 and on the slopes of the barriers 7.
- the slab before l ′ and the rear slab 2 are then assembled, so that the electrodes of the network X of the rear slab 2 cross the pairs of electrodes of the networks Y, Y ′ of the front slab Y between the barriers 7 ; the barriers 7 then serve as spacing means between the tiles 1 ', 2.
- the two tiles are sealed together in a manner known per se, the gas contained in the space between the tiles 1 and 2 is pumped out, and this space is filled with discharge gas, generally comprising xenon.
- the plasma panel according to the invention is then obtained; the structure specific to the invention of the surface of the dielectric layer 3 'at the interface with the protective layer 4' makes it possible to recover a large part of the radiation which is not directly absorbed and converted by the phosphors, so to redistribute it towards these phosphors; the light output of the panel is thus significantly improved, at a level at least comparable to that of the panels described in document EP 1085554 already cited, while avoiding a specific diffusion or reflection layer in the front panel slab; advantageously, thanks to the invention, the protective layer based on MgO can be very easily protected from any trace of water, which makes it possible to better guarantee the cathodo-emissive properties of this layer and the lifetime of the panel.
