Definitions
- the invention relates to a method for manufacturing a multilayer element with a transparent surface electrode and an electroluminescent lighting element (element EL) comprising the characteristics of the preamble of claim 1.
- multilayer element is understood here to mean a unit composed of a carrier substrate and of the element EL, consisting in itself of several layers, applied, laminated or printed on the carrier substrate.
- a surface electrode is required allowing the visible light emitted by it to pass through as much as possible.
- This electrode in principle counts as one of the layers of the functional element and most of the time forms the limit surface between the carrier substrate and the functional element.
- plastic panes for example polycarbonate
- plastic films PET - polyethylene - terephthalate
- rigid substrates after the EL element has been formed.
- On the EL element structured on its carrier substrate can follow, in order to form a laminated element, at least one more sticky intermediate layer and another (rigid) covering layer. It is true that it is not absolutely essential to embed the EL element between two rigid panes of a laminated pane, but this arrangement will be preferred for safety reasons in consideration of the very high supply voltage.
- the installation in a laminated glass also protects the EL element against mechanical effects as well as against the ingress of moisture and dirt which could cause disturbances. If transparency or light emission is only required towards one side, rigid non-transparent plates of any material can of course also be used on the other side.
- EL elements are therefore produced mostly by screen printing. This can be done by first coating the substrate (preferably by spraying) with the transparent electrode on which the layer with lighting function is applied. Then comes the dielectric layer, for example barium titanate, which has a very high dielectric constant, and then the second electrode, which does not necessarily have to be transparent. It consists of a metal that conducts electricity well, like silver preferably.
- the light emission of an EL element begins as soon as the functional layer is in an electric (alternating) field formed between the two electrodes.
- the question of knowing exactly where the dielectric separation of the electrodes is then of secondary importance. However, care must be taken to ensure that breakdowns do not occur anywhere, because these can immediately cause local destruction, extending later, of the functional layer.
- the strength of the electric field in a thick film printed EL element can be of the order of magnitude of some 10 6 V / m. If the insulation is too weak, there may be breakdowns which appear as black dots or spots. In practice, UV curing varnishes compatible for screen printing are used, for example, as additional insulation or dielectric layer.
- Document EP-A-0 267 331 discloses a laminated window for vehicles with a mark embedded in the sticky layer of the laminate, a mark which is presented or can be illuminated from the rear by an EL element.
- the necessary electric cables are practically invisible in the form of tracks or thin metallic conductive layers or oxides and transparent inside the laminate. After activation of the supply voltage, the light mark seems to be suspended in the window without cables visible.
- the cited document discloses two different variants of the EL elements. In the first, two voltage conducting electrodes are provided on the same substrate and are joined by the lighting element, which in turn includes a bridging electrode. From the electrical point of view, two capacitors connected in series are thus formed. In the second type of structure, respectively one of the two electrodes is installed as a transparent thin layer on the two internal surfaces of the laminated glass and the lighting element is arranged between them next to the separating dielectric layer.
- the transparent electrodes of the EL elements preferably consist of indium tin oxide (ITO), the light-emitting (phosphorus) layer being applied directly to this electrode to obtain a power high lighting.
- ITO indium tin oxide
- phosphorus light-emitting
- the transparent electrode is also designed for various reasons such as a multilayer system, in which a dielectric layer adjoins the functional layer EL.
- a dielectric layer adjoins the functional layer EL.
- Document DE-A-198 25 435 describes an arrangement of EL in which dielectric layers are arranged by the technique of thick layers on both sides of the illuminating layer EL. Various measures are also indicated to influence the color of the light emitted.
- German patent application 101 64 063.3 is described a laminated element with a rigid transparent pane, a transparent surface electrode applied thereon and a plane multilayer EL lighting element, of which the transparent surface electrode can be used, with the help of additional electrical connections, as a heating layer to establish predefined temperatures of the EL lighting element.
- a laminated element can for example be used in a vehicle for example as a glass roof which illuminates on the surface as interior lighting in the event of darkness in the passenger compartment.
- the invention therefore aims to indicate a method by which the number of printing operations during the printing of functional layers of an EL element on a substrate can be reduced.
- the EL element is formed on a transparent thin-film electrode, which already comprises at least part of the dielectric separating layer of the EL element.
- At least one (partial) dielectric layer is arranged between the electrically conductive electrode layer proper and the EL illuminating layer.
- the dielectric layer of the transparent surface electrode located on the top acts as an additional insulator against breakdowns.
- the printing thickness of the dielectric layer to be printed later can be considerably reduced, and a second operation can be dispensed with if necessary. screen printing for applying a layer of varnish (UV-curing varnish).
- the function of the second dielectric layer can even be completely ensured by the dielectric layer on the transparent surface electrode if its insulating effect is significant enough with sufficient transparency to light.
- the capacitance of the capacitor formed by the two surface electrodes on both sides of the functional layer is to be preserved, it is possible, thanks to the use of a very thin dielectric layer instead of a relatively thick printed dielectric layer, to reduce also the thickness of the latter, in order to adapt the whole of the dielectric constant to the reduced slit width of the capacitor.
- the insulating layer is isotropic, that is to say that it has the same dielectric properties in all directions and is free from "pinholes".
- the layer system can also be deposited on a thin carrier layer of plastic material, for example polyethylene terephthalate (PET) and connected by means of a suitable adhesive layer to a rigid substrate.
- PET polyethylene terephthalate
- the transparent electrode should preferably be constructed on a layer system which withstands high temperatures (around 650 ° C) during bending of the glass.
- Another advantage of the layer system forming the transparent surface electrode is that it has a strong thermal insulation effect. This has a very positive effect, for example, on glass roof panes for vehicles fitted with EL elements, by the fact that the subjective feeling of heat of the passengers in the vehicle is improved.
- a suitable layered system can be described as a heat-resistant reflective layer of sunlight and / or IR based on silver or other conductive metals.
- a layer system particularly suitable for the intended use described here is composed of the following succession of layers: substrate - Si 3 N 4 - ZnO - Ti / Ag - ZnO - Si 3 N - ZnO - Ti - Ag - ZnO - Si 3 N. It resists high temperatures, can therefore be applied to a glass pane before bending and / or prestressing, and it has the desired properties at the optical (transparency, color) and electrical (surface resistance, dielectric constant) levels.
- the upper anti-reflection layer or part of the upper anti-reflection layer, in particular the covering layer can be configured. located most above, as a layer of mixed oxides, that is to say a layer composed of several oxides. The hardness and chemical stability of the layered system can thus be improved.
- the mixed oxide layer consists of at least two metal oxides, one of the metal oxides of which is a Ti, Zr or Hf oxide, and the other metal oxide a oxide of Zn, Sn, In or Bi.
- Document EP-A1-0 922 681 describes a configuration of the upper anti-reflection layer in two partial layers, the upper partial layer of which consists of a mixed oxide based on zinc and aluminum, in particular with a spinel structure of the type ZnAl 2 0.
- Document DE-C1-198 48 751 describes a layered system with a layer of mixed oxides which, based on the overall metallic content, contains 35 to 70% by weight of Zn, 29 to 64.5% by weight of Sn and 0.5 to 6.5% by weight of one or more of the elements Al, Ga, In, B, Y, La, Ge, Si, As, Sb, Bi, Ce, Ti, Zr, Nb and Ta.
- Document US 4 996 105 discloses layered systems with mixed oxide layers of the composition Sn ⁇ _ x Zn x O y .
- the documents EP-A1-0 464 789 and EP-A1-0 751 099 also describe layered systems with anti-reflective layers of mixed oxides.
- the mixed oxide layers based on ZnO or SnO contain an addition of Sn, Al, Cr, Ti, Si, B, Mg or Ga.
- Layer systems that can be highly stressed at the thermal level are also known in various embodiments.
- the anti-reflection layers which are separated from the functional layer in silver by thin metallic blocking layers in CrNi consist respectively of Si 3 N.
- the layer system described in document EP 0 883 585 B1 also belongs to this group, the metal blocking layer however being in this case composed of Si.
- Such layer systems are certainly very stable at the thermal level, but are, because of the known problems during the projection of nitrides, very expensive to manufacture.
- the projection of relatively thick layers of Si 3 N 4 is not without problems due to mechanical tensions in the layers.
- document DE 196 40 800 C2 describes a layered system in which there is, between the metallic blocking layer and the oxide or nitride covering layer, an intermediate layer of compound nitride or nitride oxide of the metal of the metallic blocking layer.
- Another layer system of this type known from document DE 101 05 199 Cl is distinguished by the fact that between the silver layer and the metallic blocking layer, there is a layer of SiN 4 or AlN.
- an intermediate layer at least 5 nm thick in Ti0 2 is placed between a metallic blocking layer of Ti and the covering layer and, on this intermediate layer a covering layer of an oxide, a nitride or a nitride of Bi, Sn, Zn oxide or a mixture of these metals.
- the individual layers consist of purely oxide layers.
- the oxide layers can in most cases be produced more simply and more economically than the nitrided layers.
- the metallic blocking layer has, however, in these cases a relatively large thickness.
- a layer system of this type is described for example in the document DE 198 52 358 Cl.
- the blocking metal consists in this case of an aluminum alloy with one or more of the elements Mg, Mn, Cu, Zn and Si in as components of the alloy.
- FIG. 1 is a sectional view of a laminated window with an electroluminescent surface element, which is constructed on a transparent surface electrode comprising at least part of the dielectric,
- Figure 2 a detailed view of a contact area for establishing the external connections of one EL element.
- a layer system 2 very transparent for visible light system which comprises at least one metallic layer 2.1 - preferably silver - electrically conductive.
- This layer 2.1 constitutes the transparent surface electrode proper of the element EL.
- a anti-reflection dielectric layer for example made of silicon nitride (Si 3 N 4 ) as well as possibly a layer of zinc oxide (ZnO) promoting the growth of the silver layer 2.1.
- a dielectric layer 2.2 which constitutes in the context of the invention part of the dielectric of the capacitor in the field of which the element EL is made to light.
- other layers for example blocking layers, which guarantee in a reproducible and lasting manner the desired properties of the entire layer system during production, during further processing and in the assembly state can be added.
- a strong mechanical resistance to wear can also be obtained by the composition and the combination of the upper (covering) layers of such a layer system; the Si 3 N layers in particular are suitable as outer covering layers because of their high hardness.
- the transmission of the coated window 1 for visible light is preferably at least 75%. This is a minimum value required in Europe for vehicle windshields.
- the glass pane 1 provided with the layer system 2 generally forms the substrate for the element EL.
- the illuminating layer 3 of the element EL is printed - preferably by screen printing process - on the outer layer of the layer system 2 so as to leave free at least on one side a narrow border strip of the layer system 2.
- This border strip is used for the electrical contacting of the electrode layer 2.1.
- a conductive track 6 is printed on the free edge of the layer system 2; this is preferably carried out during the same operation as the printing of the second surface electrode 5.
- the conductive track 6 forms the electrical connection for the voltage supply of the layer of transparent electrode 2.1. It is symbolically indicated that the material of the conductive track 6 passes through the dielectric layer 2.2.
- a pair of cables shown in a very simplified manner represents the external electrical connections 7 of the two electrodes 2.1 and 5. The manufacture of such connections, in particular by welding, is known per se. For the present case of application, specific measures which will be the subject of more precise explanations in connection with FIG. 2 must however be taken if necessary.
- the printed layers 3 to 5 and the conductive track 6 are significantly thicker than the individual layers of the layer system and than this as a whole; the actual relationships cannot be represented to scale here. This is why the thicknesses of the printed layers are only partially shown and interrupted by dotted strips. While the total thickness of a layer system that can be highly stressed thermally and preferred for this application case can vary between 130 and 180 nm, for example depending on the desired coloring, the printed layers 3, 4 and 5 of the EL element are significantly thicker.
- the following table is a comparison of the traditional EL elements according to the recommendation of the manufacturer Dupont and reduced thicknesses with the transparent electrode modified according to the invention.
- both the actual illuminating layer and the other layers of the EL element can be made thinner.
- the supply of the EL element with alternating voltage by means of its two electrodes 2.1 and 5 is symbolically indicated by an arrow designated by U, its surface light emission in the alternating electric field applied by a series of arrows which pass through the layer system 2 and the window 1 starting from the functional layer 3.
- a sticky layer 8 which extends to the outer edge of the window 1. It connects by the surface a second rigid window 9 with the window 1 and with the layers applied on it.
- the pair of cables 7 is also embedded in the adhesive layer 8.
- the sticky layer forms an airtight seal of the components of the EL element. It also protects the layered system 2, since it is connected directly by adhesive in the uncoated border area of the window 1 with the surface of the latter.
- the sticky layer can be produced from a thermoplastic film which can be melted or from a transparent mass which can be cast, which is integrated in a manner known per se into a determined intermediate space between the two rigid panes 1 and 9 and then hardened .
- An opaque edge coating not shown here and known per se can be provided in the border area mentioned, formed by a preferably baked screen-printing paste, which can also be used for the optical plating of the cable connection and possibly of the conductive track 6.
- This edge coating would preferably extend from the outer edge of the glass inward to a distance such that its end extends just below the outer edge of the illuminating layer 3, while can be placed on or under the edge of the layer system 2, that is to say it must be applied before or after the deposition of the latter.
- the contrast in the transition from the opaque coating to the illuminating surface can be attenuated if necessary in a manner known per se by a gradation of the embedding type.
- Figure 2 shows in detail an embodiment of a connection field for the EL element, which is particularly suitable for fitting into a laminated glass. There is a top view on the coated surface of the window 1.
- a contact field 10 is deposited in a manner known per se on the rigid window 1 - if possible on its edge -, unlike the greatly simplified representation of the cable line in FIG. 1, field on which the contact surfaces to be connected to the outside are grouped so as to be very close to each other. This gives the advantage of simultaneous welding, possibly automated, with the cable sections to be guided outwards.
- a presentation of such a multiple connection field can be found for example in document DE-C2-195 36 131.
- the conductive track 6 is practically directed like a frame around the overall surface of the element EL. This frame is interrupted, in the region of a conductive track section 6 ′, in the form of a connection with the second surface electrode 5.
- the electrical connection between this conductive track 6 ′ and the surface electrode 5 must naturally be established also in the interest of such a homogeneous introduction as possible of the electrical potential in this surface, no particular requirement being imposed, however, because of the greater thickness of the surface electrode 5 - compared to the thickness of the transparent surface electrode 2 - and of the less surface resistance of the latter.
- the section 6 ′ was simply manufactured both with the surface electrode 5 and the conductive track 6 by screen printing of an electrically conductive paste during the same operation.
- the contact zone 10 on which the solder contact points for the external connections 7 are located (indicated here only in dotted lines in the form of conductors in flat strip), is free of the coating 2 (or n ' is initially not coated at all).
