Description

200916335 IX. Description of the Invention: [Technical Field of the Invention: j The present invention relates to a writing board having an EL (electroluminescence) element (hereinafter referred to as an EL element), a manufacturing method thereof and use thereof. 5 [Prior Art] In particular, the present invention relates to a writing pad of a specific thick film AC electroluminescent device having at least one plane having at least one upper transparent polymer film and having a lower side of the writing plate Flexible substrate. Disposed on the lower substrate is a conductive structure and an energy supply device and operating electronics, the latter including at least one on/off switching system and a charging system. The upper polymeric film and the underlying substrate are integrally molded with a thermoplastic plastic material surround such that the writing sheet is at least protected from spraying onto the water. Still further, a method for producing a tablet having at least one electroluminescent element 15 is disclosed, in addition to the prior art, the energy supply and the operating electronics, including at least one on-off switching system and charging system, Disposed on the lower substrate, the unit is then provided with an integrally molded plastic material surround in an injection molding tool, and the integrally molded plastic material has the properties of a flexible body. Further, the use of a writing pad or writing pad or signal board is revealed, so that it can be written directly on the writing field using a waterproof bar 'or preferably written on it. - on a waterproof writing list, and 忒 writing and/or writing can have a graphical configuration, so a protocol can be filled out or general precautions can be recorded, and thus, when fighting fires with 5 200916335 and rescue services When used by the military, the military and the coffee, the writing board can be used in poor light or no light, or in a fuzzy environment. U.S. Patent No. 5, G. No. 242 discloses an illuminated underwater writing board in which light can be introduced into the writing pad at one edge via a chemically actuated light bar. This system is neither based on a planar zinc sulfide electroluminescence electroluminescent thick film AC film nor on any electrical chargeable properties. The use of a chemiluminescent light bar has the disadvantage of having only a low optical density in a short illumination period. Therefore, the disadvantage of this configuration is that it does not have a planar light source but a light-emitting diode that is presented as a period of time, which illuminates an area that is illuminated only by incident light. Thus, in the case of the above document, there is Disadvantages, first of all, the energy source is arranged to separate from the illuminated plate, a partition associated with increased cost and complexity. Thus, the user of the illuminating panel must be accompanied by a light source and associated electronics in a strip, and the wire forming the electrical connection to the tablet will ruinly interfere with the operation of the tablet. In addition, its overall configuration does not prevent moisture, which can cause electrical and connecting wires to fail under the influence of moisture or harmful shocks. A further disadvantage is that a light blurring effect will only be emitted upwards, and it does not provide a source that also emits downwards simultaneously. U.S. Patent No. 5,163,748 discloses an illuminated clipboard in which the illumination device is arranged in the region of the splint in such a manner that the surface of the splint is illuminated. In this system, a planar sulphide electroluminescent body electroluminescent thick film AC film is not disclosed, and the luminescence is unaffected by the light from below, but is affected by the incident light. U.S. Patent No. 5,381,31 discloses an illumination device for reading and/or writing on a board in the presence or absence of a light, using an electroluminescent film. In this case, the electroluminescent film is arranged in the lower recess of the splint. Since the clipboard is used to connect a writing pad, the electroluminescent film is therefore not directly configured; this will be avoided in the present invention 'the entire (four) layer configuration and form of % luminescence Suitable for (injected) surrounds to incorporate 'encapsulations containing electronic components. U.S. Patent No. 6,95l4〇3B2 discloses a illuminating device for a generally flat surface 10 15 in which the ray is self-illuminating in a unit having a light guiding element at the edge; 隹λ, And exit in a flat manner. In this U.S. Patent No. 6,951, 4〇3Β2, An ★ μ ^ 致 致 致, / β 面 文件 , / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / The source, the money line then exits via the flat surface. In the above documents, .g, 匕, has the disadvantage that the flat light pressure is not achieved, and in addition, only the uneven light scattering region is provided. European Patent No. EP, in which the light is revealed in the case of No. 1 - the luminous panel is equipped with this European patent ΕΡ〇 = = and exits in a flat manner. In the case of a planar electroluminescent film, it is not mentioned that the light is emitted to the light-guiding element J A and the light source, which, via the edge, thus exits the document and then exits via the planar surface. And the same shortcomings. In the case of U.S. Patent No. 6,951,403, 2, the invention provides a writing board that can completely guard against water in a variety of strict use situations. The spraying can also accept mechanical shock, and in which the light source can emit light upwards and downwards. In order to achieve this, the present invention is characterized by the technical teachings of the first item of the patent application. In accordance with the present invention, one of the main features of the present invention is that all components are disposed in the tablet itself and in a manner that they are protected from spraying onto water and configured to be protected from damage. 10 This goal can also be achieved by the use of, for example, an inductive charging station that has no accessible ohmic contact points from the outside. A further advantage in accordance with the present invention is that it provides a transparent writing board side facing away from the illuminated surface (below the writing pad). This has the decisive advantage in that the optical mode effect is directed forwardly to the 15 sheets to be written thereon and at the same time also to the rear of the writing sheet, so that the surrounding area can also be written at the same time. The board is illuminated. In this way, if the writing board is placed somewhere, for example, it is not necessary to always place the front side of the writing board upwards. The writing board can also be found very easily. Therefore, when used in a disaster area generally filled with a smog environment, the book 骂 骂 骂 can be found very easily and operated very easily. The exterior of the tablet is 'in addition to its inherent flexibility, which results in a completely uniform illuminated writing plate from spraying onto the water, while continuing to operate in a full-filled smoke ring* and simultaneously sprayed when exposed It can also be used when water is used. This is not available in the prior art. 200916335 BRIEF DESCRIPTION OF THE DRAWINGS Some embodiments of the invention will be described in more detail below with reference to the accompanying drawings in which: FIG. 1 is a top view exploded view of an example of a tablet (1) having a field-induced 5 illuminating element ( 2), having a writing sheet (4) and a writing stick (5) sandwiched therein; the second drawing is not a part of the example writing board, which has an electroluminescent element (2) The writing sheet (4) and the writing stick (5) sandwiched therein; Fig. 3 shows the decomposition of the portion 10 pattern by one of the examples of the electroluminescent element (2).

[Applied Method; J In the top exploded view shown in Figure 1, an example tablet (1) has an electroluminescent element (2) and a writing sheet (4) and a writing stick ( 5). 15 The electroluminescent element (2) screen printing technology is produced from the electroluminescent paste 'that is, using thick film technology' and utilizes a parent current of about 100V to 200V or more and a frequency greater than 50Hz and generally from 400Hz to It is operated in the 800 Hz range and is also above this value in the case of high radiance values. 20 Because of this, the electroluminescent element (7) as a writing board (1) must be elastically deformable in its application and must be used under strict operating conditions. The structure of the electroluminescent element (7) is designed to be highly variable. In particular, the 'polyamide S is the main screen. The ink system is used and a reversible and/or deformable configuration is selected to be used at least for the front electrode of 200916335. - A flexible and/or deformable configuration can also be selected for use in the back electrode. The electroluminescent element is deformable in three dimensions; its radius of curvature may be less than 2 mm, preferably less than imm. The deformation angle can be greater than 60. It is better to be larger than 75. Especially the best 5 is bigger than 90. More specifically, it is preferably larger than 1〇5. . In this case, an intrinsically conductive polymer, for example, Baytr〇nP_ as a main polymer, may be used, or depending on ITO (indium tin oxide) or AT〇 (yttrium tin oxide) dispersed in a polymer matrix. The thin, predominantly transparent, and conductive polymer layers of the particles can be used. In addition, SWCNTs (single walled 10 _ carbon nanotubes) can be blended so that the risk of bursting through excessive stretching or excessive deformation can be reduced or avoided. In principle, a splashed ITO electrode can also be used at the same time. In this case, the overall system must be configured substantially more rigorously because the -IT〇 electrode is susceptible to bursting and tilting due to excessively small bending radii or excessively large deformations and thus can result in an electroluminescent field. (2) or its parts are invalid. The transparent front electrode having a surface resistance value of from about 30 ohms/square to 60 ohms/square and as high as 600 ohms/square is usually surrounded by a so-called bus bar, and in this way, one has a general self-twisting 5 A uniform electroluminescence field to the 4 or Β4 scale can be generated. 20 The electroluminescent element (2) is typically produced from an individual transparent film of at least PET or polycarbonate (pc) and having a film thickness of typically 125 μm or 175 μm and above. The outside of the film constitutes the writing field (12) and may have a corresponding surface structure. A mat or satin finish surface structure provides good resistance to damage and acts as a diffusing agent for electroluminescent radiation. Principle 200916335, the transparent upper film can also be composed of two films, and the second film can be cast through the laminate, so that another protective film can be completed. A primary transparent and electrically conductive layer having a surrounding bus bar is disposed on the inner end of the front transparent film or a graphic design (13) can be disposed thereon. The electroluminescent layer 'is primarily composed of microencapsulated zinc sulfide electroluminescent bodies that are identically dispersed in a polymer matrix (preferably depending on the polyurethane and the like of the permanently flexible polymer). Is configured. The electroluminescent layer can have a desired emission color via the selection or mixing of electroluminescent pigments. Color shifting dyeing and/or pigmenting (Stokes shift) can also be blended at the same time, and in this way, a white emitting color, for example, can be accomplished. Since this blend blend typically has an intrinsic color in the range from pink to orange, a thin layer, for example, a titanium dioxide dioxide dispersed in a polymer matrix, can be arranged at 15 for the electroluminescence. Above the layer, a white surface can be achieved. In the development of the present invention, pigments having a long afterglow time can be simultaneously incorporated into the electroluminescent layer or polymer matrix. For a fast rechargeable afterglow layer, a low cost sulphide afterglow pigment can be used, and for a slower chargeable afterglow layer, an aluminate or silicate pigment (most preferably a rare earth element) Used, the pigment has an afterglow lasting up to 2000 minutes and above (suitable for dark viewing and with a fully charged afterglow pigment). The mixing of the above-mentioned afterglow pigments is also often used. In this case, the emission color is selected from the group consisting of micro green-micro blue-yellow to blue and red 11 200916335, which continues to vary strongly for different pigments. The advantage of this blend of afterglow pigments is that the writing field (12) can remain illuminated even if the energy supply fails, although typically only a few mcd/m2 and not close to 2 to 10 cd/m2. 5 cases when the field illumination field energy supply is operating. The electroluminescent layer is typically produced using screen printing. In principle, the dot-shaped electroluminescent element can be printed using this fabrication pattern. The actuated electroluminescent surface can be reduced and the electroluminescence energy supply can be scaled down by a plate grid of such a luminescent point or a small geometry. Further, the entire writing board (1) can also be formed translucent at the same time and has a mainly transparent rear side (3, 17) in the configuration, and the entire writing board (1) is increased in transparency. A configuration using an grid-like electroluminescent element can be achieved. The back germanium electrode is achieved after the insulating layer, or typically two layers of printed insulation. However, depending on the transparent, translucent or non-translucent form configuration, the rear electrodes can also be fabricated integrally, that is, directly connected to the insulating layer, or stacked separately via appropriate electrode configurations. . The rear electrode can be integrated into the electroluminescent layer (2) sequence, or it can be formed on the substrate (3) using a conductive back structure (17). 2 〇 The substrate (3) may then be an integral member or a separate member of the electroluminescent element (2). The substrate (3) may have the form of a thin printed circuit board having a wiring structure (17). However, a large transparent polycarbonate film (pc film) or an ABS film and the like polymer materials can also be selected. In this case 12 200916335, the electrically conductive structure can be produced by printing, stamping or wiring. A member (6 7 8, 9) is disposed on the substrate (3). The wiring or connection of the components is formed via the conductive structure (17) and electrical contact can be formed by conventional soldering, laser splicing, soldering, ultrasonic welding, conductive bonding, and the like. The respective components are positioned via the joint or ϋS technique and at the same time can also be covered protectively via the resin system and the dispensing application and thus protect the subsequent injection-molding process. In principle, in accordance with the present invention, it is preferred that each of the electroluminescent elements or electroluminescent arrangements that follow the general configuration described below be suitable for use in the inventive tablet having electroluminescent elements. However, it will be apparent to those skilled in the art that each of the other electroluminescent elements or each of the other electroluminescent arrangements having the same or corresponding functional characteristics of the electroluminescent elements or electroluminescent arrangements of the general construction described below are The utility model can be applied to a light-emitting sheet or a light-emitting panel member. Preferably, the field-illuminating element is constructed from at least one substrate and at least one electroluminescent arrangement, which is preferably produced in the layer by screen printing techniques, but may be, for example, Use blade application, spray, spray and/or coloring techniques. To achieve this, the substrate may first be covered with a transparent electrode on the surface, and a light-emitting layer (field-emitting layer) is then applied thereto. Finally, an insulating layer (dielectric layer) and - further electrodes can then be disposed on the luminescent layer. The starting point of the electroluminescent arrangement according to the invention is thus the conductive electrode layer applied to the substrate. 13 200916335 The electroluminescent element can thus be configured to have side illumination of the substrate in an electroluminescent arrangement, or to illuminate light from an electroluminescent arrangement applied to the rear portion thereof via at least a partially transparent substrate. Still further, the illumination can also be emitted from both sides if the substrate is at least partially transparent. 5 In a first embodiment of the invention, the electroluminescent element consists of the following layers (conventional structure): a) - at least partially transparent substrate, member A; b) at least one electroluminescent arrangement, member B Applied to the substrate and comprising the following members: 10 ba) - at least partially transparent electrode, member BA, as front electrode; bb) selective insulating layer, member BB; be) - containing one available At least one luminescent pigment layer excited by an electric field (electroluminescence), referred to as an electroluminescent layer or pigment layer, member BC; 15 bd) one of the selective insulating layers, member BD; be) - rear electrode, Member BE, which may be at least partially transparent; bf) - a conductive track or a plurality of conductive tracks, member BF for electrically contacting both member BA and member BE, wherein the conductive tracks may be applied to electrodes BA and BE Preferably, before, after or between, the conductor rails are applied in one working step.

The reflective layers can be configured, in particular: _ outside of component A, 10 • between component A and component BA, _ between component BA and component BB' or if component bb is not present, then component BA Between the member BD and the member BC, between the member BD and the member BE, between the member BE and the member BF, 15_ between the member BF and the member CA or CB, - outside the member CA or CB. The reflective layer, if present, is preferably disposed between the member bc and the member BD or, if the member BD is not present, between the member BC and the member BE. The reflective layer preferably contains small glass spheres, especially small hollow glass spheres. Small glass sphere diameters can be varied within wide limits. For example, they may have a size d5 from a typical 5 μm to 3 mm, preferably 1 to 200 μm, and particularly preferably 2 to 。. The small hollow glass sphere is preferably embedded in an adhesive. 15 200916335 In another embodiment of the invention (in the reverse layer, the electroluminescent element consists of the underlying layer a) - at least partially detached substrate, member A, 1 placed, member B, applied to The substrate and b) at least the field-initiated first comprises the following components: be) - the rear electron core 'the element BE, which may be at least partially transparent bb) selective <~Insulating layer, member BB, be) - containing at least _ luminescent pigments excited by a beta-electric field (electroluminescence) 10' is called the electroluminescent layer or pigment layer, BC, bd a selective _ insulating layer, member bd, ba) - at least partially transparent electrode member BA, as a front electrode, bf) - a conductive track or a plurality of conductive members, member BF for electrically contacting member BA and Both of the members BE, the conductive tracks thereof can be applied before, after or between the electrodes BA and BE, which are preferably applied in one working step.

Additionally, one or more at least partially transparent patterned configuration layers can be disposed on the transparent protective layer C and/or between the transparent protective layer C and the electroluminescent configuration. In particular, the graphical configuration layer can replace the 16 200916335 protection layer function. In a particular embodiment of the reverse layer structure, both of the members B, c can be applied to the front end of the substrate, member A, and the back side, and can also be applied to both sides of the substrate. (two-sided structure). In this case, the BA to BF layers on both ends may be the same, but they may also be different in one or more layers, and thus, for example, the electroluminescent elements are equally emitted on both sides thereof, or The electroluminescent elements have different colors and/or different brightness and/or different graphical configurations at each end. In addition to the above layers (members A, B*C), the electroluminescent element of the present invention having a reverse layer structure may have one or more reflective layers.

It will be understood by those skilled in the art that The specific embodiment of the above-described common structure and the 17 200916335 feature 'are equally applied to the reverse layer structure and the two-sided structure unless otherwise stated. The one or more insulating layers BB and/or BD, Both the common structure and the reverse structure can be omitted, in particular, if the member BC 5 has its thickness, it prevents a short circuit between the two electrodes, the members BA and BE'. The features of the respective components will be explained below: Electrode The phosphorescent element according to the invention has a first at least partially transparent front electrode BA and a second electrode 'rear electrode be. 10 Within the meaning of the present invention, the wording, , at least partially transparent, should be understood to indicate self-transportability (generally more than 60%, more preferably more than 7〇%, and preferably more than 80%, especially more than 9〇〇/0) The electrode constructed by the material. The rear electrode BE is not necessarily transparent. It will be understood by those skilled in the art that suitable conductive materials are well known for the electrodes themselves. In principle, the fabrication of thick film AC electroluminescent elements using alternating current excitation Many forms of electrodes are suitable. These are, firstly, injected or evaporated-deposited into a thin film of indium tin oxide (ITO) on a plastic film in a vacuum. They are very thin (several hundred A) and Provides a high transparency advantage with a relatively low surface resistance (approximately 60 to 6 〇〇〇). 2 Further, the printed poly contains TM or bismuth (antimony tin oxide) or essentially conductive transparent polymer 黎 (plane) The electrodes are printed on the screen for self-study. They can be applied, mainly, any desired structure is also on the surface of the structure. In addition, they provide relatively good thinness. Also use non-ιτο screens - Printed layer (which makes 'Non_ΙΤ〇' 18 200916335 refers to all screen printed layers that do not depend on indium tin oxide (IT0)) 'that is, essentially has a nano-scale conductivity Conductive polymer layer. For example, a screen-printing paste with a number of 7162Ε or 7164 of DuPont, an intrinsically conductive polymer system, for example, Agfa's Orgacon® 5 system, HC Starck GmbH's Clevios® multi (3 , 4-acetyl dioxin, a system known as Ormecon's organometallic (PEDT, conductive polymer polyethylene dioxythiophene), Panipol Oy's conductive coating or printing system, optionally with Highly toughness adhesives (for example, polyaniline based on PU (polyurethane), PMMA (polymethyl methacrylate), PVA (polyvinyl alcohol) or modified 10 can be used. It is best to use H. C. Starck GmbH's Clevios® poly-(3,4-ethylenedioxythiophene) system. Examples of conductive polymer films are polyaniline, polythiophene, polyacetylene, polypyrrole (Handbook of Conductive Polymers, 1986) with and without metal-oxide fillers. According to the invention, in each case, with respect to clevi〇sp, aevi〇s 15 PH, Clevios P AG, Clevios p HCV4, Clevios P HS, Clevios PH 500, Clevios PH 510 or any desired mixed printing paste thereof The total weight is from 10 to 90 wt.%, preferably from 20 to 80 wt.%, particularly preferably from 30 to 65 wt.%, which is preferably used to formulate a printing paste which produces a partially transparent electrode BA. As solvent, dimethyl hard (DMS 〇), 20 N, N-dimethyl decylamine, N, N-dimethyl acetamide, ethylene glycol, glycerin, sorbitol, methanol, ethanol, Isopropanol, N-propanol, acetone, methyl ethyl ketone, methionine, water, or a mixture of two or more of the above solvents may be used. The amount of solvent in the printing paste can vary over a wide range. For example, in the formulation of a slurry of the present invention, a solvent of 55 to 6 in % 19 200916335 may be included, and in another formulation of the present invention, a mixture of two or more solvents in the vicinity of about 35 to 45 wt% Can be used.

As a drilling agent, for example, Bayderm Finish 85 UD, Bayhydrol PR34〇n, Bayhydrol PR135 or any combination thereof, the amount thereof is preferably about 0.5 to 10 wt_°/〇, preferably 3 to 5 wt·%. Can be included in the 10 formula. The polyurethane distribution according to the present invention is used to form an adhesive of a conductive layer, preferably a water-like polyurethane, after the conductive layer has dried. According to the invention, in particular a preferred formulation for the printing paste for producing a partially transparent electrode BA comprises: substance content / content content / content / wt.% / wt.% wt.% Wt.% Clevios P HS (HC Starck) 33 48 40 42.2 Silquest A187 (Oscar specialty) 0.4 0.5 1.2 1.0 N-methyl fluorenone 23.7 14.4 10.3 13.3 Diethylene glycol 26.3 20.7 30.0 25.4 Proglyde/DMM 12.6 12.4 14.5 13.6 Bayderm Finish 85 UD (Lanxess '! 4.0 4.0 4.0 4.5 Substance content/wt.% content/wt.% Clevios P HS (HC Starck) 33 40 Silquest A187 (Oscar specialty) 0.4 1.2 N-methyl fluorenone 23.7 10.3 Diethylene glycol 26.3 30.0 Proglyde/DMM 12.6 Γ 14.5 Bayhydrol P340/1 4.0 4.0 20 200916335 According to the partially transparent electrode BA of the present invention, in the above-described variation of the formulation from the partial transparent electrode BA, the latter is produced in advance, and the commercially available printing is performed. Li's example here can be used: Agfa's Orgacon EL-P1000, EL-P3000, EL-P5000 or EL-P6000 series, preferably 5 EL-P3000 and EL-p6〇〇〇 series (especially For deformable applications). Also 'tin oxide (NESA) slurry can be used as a suitable electrode material. Further, the above-described conductive material can be applied to a carrier material. A transparent glass layer and a thermoplastic film, for example, are also suitable. The corresponding carrier material will be below. More specifically illustrated. In the context of the present invention, ten or two carrier substrates can be used. These electrode materials can be applied to screen printing, knife coating techniques, mouth spray, spray, and/or coloring techniques to The corresponding carrier material (substrate), for example, dried, is then carried out at a low temperature, for example, 80 to 12 CTC. In a preferred embodiment, the 'conductive coating is applied via a vacuum or heat split 15 solution. In other embodiments, it is preferred that the electrically conductive coating be a thin and mostly transparent metallic ruthenium metal-oxide layer produced via vacuum or thermal decomposition, preferably having from 5 ιηΩ to 3000 Ω/square. The surface resistance is particularly preferably a surface resistance of 0.1 to 1000 Ω/square, more particularly preferably 20 is 5 to 3 Ω Ω/square, and, in a further preferred embodiment, - sunlight transmission is at least It is larger than 60% (> 60 to 100%) and especially larger than 76% (> 76 to 100%). Further, conductive glass can be used as the electrode. The thermal decomposition generating layer is a specific preferred type of conductivity and high yield 21 200916335 transparent glass, especially floating glass, the layer of which has high surface hardness and electrical surface resistance, which can be from a few milliohms to 30 一般 in general. 〇〇/square is adjusted within a very wide range. This type of thermal decomposition cover glass layer has good variability and good scratch resistance; in particular, scratching does not cause electrical interruption of the conductive surface layer, but only causes a slight increase in surface resistance. Further, the conductive surface layer generated by thermal decomposition is strongly diffused into the surface and fixed to the surface via heat treatment, so that when a material is sequentially applied, a very strong adhesive bond to one of the glass substrates is applied. It is formed by 10, which is also a very advantageous point of the present invention. Moreover, such coatings have good homogeneity, i.e., low dispersion of surface resistance values over a large area. This feature is also an advantage of the present invention. The electrically conductive and south transparent layer can be formed on a glass substrate, which is preferably used in accordance with the present invention' which is significantly more effective than on a polymer substrate (e.g., PET or PMMA or PC). And more economical. The electrical surface resistance with a glass coating is on average greater than a factor of 10 on the polymer film of the glass layer of relatively transparent, that is, compared to 30 to 100 Ω/square on the PET film, for example, The glass layer is 3 to 1 Ω Ω/square. 20 Rear electrode, member BE - as in the case of a generally at least partially transparent electrode - is a planar electrode 'but' does not need to be transparent or at least partially transparent. It is generally applied to the insulating layer, if any. If the insulating layer is absent, then the rear electrode is applied to a layer comprising at least one luminescent material that can be excited by an electric field. In another embodiment, the rear 22 200916335 electrode is applied to the substrate A. The rear electrode is generally constructed of an inorganic-based or organic-based conductive material such as 'silver metal, and the material to be used is preferably not used for the high-pressure deformation method for producing the three-dimensionally-sized deformed film element of the present invention. 5 suffered damage.

Mixture of 2〇acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexyl ketone, methyl bromide, di- or more of these solvents, in particular, a preferred blend of protective lacquer CA according to the present invention For example: 38 25 200916335 Substance content / wt.% content / wt.% content / wt.% content / wt.% Desmophen 670 (BMS) 18.9 22.0 17.3 22.0 AdditolXL480 (in 50wt·% of butoxylate) 1.2 0.8 1.0 0.8 Desmodur N75 MPA (BMS) 20.0 20.0 17.4 20.0 Acetyl propyl acetate 4.5 8.5 4.3 0 Propylene glycol methyl ether acetate 0 0 0 8.5 Titanium dioxide 55.4 48.7 60.0 48.7 Substance content / wt.% Desmophen 1800 (BMS) 22.9 Additol XL480 (in 50 wt.% of butoxylate) 1.1 Desmodur N75 MPA (BMS) 12.9 Ethoxypropyl acetate 10.6 Titanium dioxide 52.5 Substrate 5 According to the electroluminescent device of the present invention, on one side or two of the respective electrodes On the side, it is also possible to have a substrate, for example, glass, plastic film and the like. Preferably, in the electroluminescent device according to the invention, at least the substrate in contact with the transparent electrode is translucent in the interior of the illustrated illumination and 10 has an opaque overlay configuration. An opaque overlay configuration is known to indicate that a high resolution graphical configuration is used and/or opaquely covered by a large area of the electroluminescent region and/or is configured translucently in a smooth manner to Used for the purpose of identifying red-green-blue signals. Further, preferably, the substrate in contact with the transparent electrode BA is a thin film of 15 which is deformable by cold drawing at a glass transition temperature Tg. 39 200916335 This creates the possibility of deforming the electroluminescent element that occurs in three dimensions. Further, preferably, the substrate in contact with the rear electrode 8 is a film which is also deformable by cold drawing under Tg. This creates the possibility of deforming the electroluminescent element that occurs in two dimensions. Further, preferably, the electroluminescent element is deformable in a three-dimensional manner, and in particular, can be deformed by cold drawing under Tg, so that a precisely shaped three-dimensional shape is obtained. The three-dimensionally deformable element can be integrally molded with a thermoplastic material on at least one side of the injection molding tool. 10) According to the field of the present invention, the sizing agent (the screen printing paste) is usually applied to a transparent plastic film or a glass layer, which sequentially has a large part of transparency. The electrically conductive coating and thus the electrode for the observation end. The dielectric, if present, and the back electrode are then produced using a printing and/or laminate process. However, a reverse fabrication process is also possible, so that the rear electrode is first produced, or the rear electrode is used in the form of a metallized film and the dielectric is applied to the electrode. The electroluminescent layer, and subsequently the transparent and electrically conductive upper electrode, is then applied. It is selectively formed into a sheet having a transparent cover film and is thus protected from water vapor and mechanical damage. In an embodiment of the invention, the conductive track (silver busbar) can be applied to the substrate A as the first layer. However, in accordance with the present invention, they are preferably applied to electrodes BA and BE, respectively, to any of the two working processes, 40 200916335, or collectively applied to the electrodes in one working step. The electroluminescent layer is typically applied using a printing process through screen printing or dispenser or inkjet applications, or using a knife coating process or a roller coating process or a curtain coating process, or a transfer process 5 order, which is best printed through the screen. The electroluminescent layer is preferably an insulating layer applied to the surface of the electrode or selectively applied to the rear electrode. As an energy supply (6), a rechargeable battery is preferably used and a relatively small or flat battery having a good charging characteristic curve and a small discharge characteristic can be used. Modern electroluminescent converters can be operated from a 3V straight current and require a small current. The turn-on switch (7) or button can be fabricated in a variety of ways and can be fabricated, for example, in the form of a capacitive electric field or a variable field, and thus meets the need to be sprayed to water. The operating electronics (8) comprise an electroluminescent converter, i.e. an electronic circuit, 15 which converts a DC voltage (6) from a battery into an alternating current, typically from 100 to 200 V and generally from 50 Hz to 400 Hz. Up to the kHz range. For small EL fields, very small wafer inverters can be used; these often include ancillary devices for operating two EL fields, or with power down electronics or perceptron-controlled brightness adjustment. 20 Further, the charging form of the battery (6) is configured in the operating electronics (8). As is schematically illustrated in Fig. 1, an inductive charging system (9) uses a coil (1 turns) and a hole or opening (n) or recess for the inductive charging system. In the electronic charging process, the opening (11) is above a charging device spindle and the charging operation is carried out in this manner. This system has been validated millions of times in 41 200916335 electrical toothbrushes. In principle, however, the ohmic contact can also be implemented at the same time and can be applied to the low voltage at which the battery (6) is charged. These electrical contacts can be configured as non-oxidized metal surfaces, or commercially available for use with DC low voltage. According to the invention, this charging operation can also occur via capacitive energy transfer. The integral-cast plastic surround (15) can be produced via a plug-in injection mold or can be made in a two-part configuration. 10 In this case, the permanent flexible plastic material, for example, is preferably thermoplastic elastomer of Bayer MaterialScience's thermoplastic polyurethane (TPU) or Kraton® (Kraton Polymer LLC) with the trade name Desmoflex®. Body (TPE) and similar thermoplastic materials are used. The two component plastic configurations (15) can be formed in the following manner, for example, 15 in the upper region of the electronic component (6, 7, 8, 9) or in the electroluminescent film (2) connection region to produce a separate The spray mold covers the element and the cover element is attached to the spray jaw type surrounding element. In all cases, 'note that the writing board (1) meets the requirements for spraying to water protection and meets the requirements of the 94/9/EC (Atex 95) guidelines for explosion-proof equipment 20 and is therefore wet and ambiguous. And can be used in an environment that may explode. The clamping device (16) can be formed collectively with the plastic surrounding member (15) as a two-component plastic component having certain manufacturing advantages. However, the clamping device (16) can be configured equally well as a separate piece of plastic material or can be connected to the plastic element (10) as a metal part. (4) The component (16) must be secure. Holding or clamping the reading list (4) H ' The clamping device (16) can also be configured in sections or in a plurality of forms only on the writing () or the evening edges. 5 At the same time, the plastic surround (15) has a fixed function through fine particles. The writing list (4) is fixed on the writing field (12) through the fixed skirt, especially the clamping device (16)' and the user can write a note (14) or a report or opinion through the writing stick (7). On the writing sheet (4). The writing sheet can be waterproof depending on the use of the area and the note paper (14) can also have water resistance as with π. To improve the configuration of the protocol (14), the electroluminescent element (7) of the writing field (I?) can be provided - the graphical configuration (π), which contains the appropriate inputs and thus assists in the editing of the protocol. In addition to the above-described clamping device, a fixing and holding device that is useful to those skilled in the art to fasten a substantially two-dimensional paper or sheet-shaped object can be used. For example, the sheet can be rotated in the form of a web to a first roller mounted on the tablet, and after the text is inscribed, can be rotated to a second roll configured relative to the first roller On the shaft, the sheet is directed through the electroluminescence to illuminate the area of the area 20 of the tablet for receiving inscription text. Figure 2 shows an exploded view of an exemplary writing tablet via one of the writing sheet (4) having the electroluminescent element (2) clamped thereon and the writing stick (5). In this exploded representation, the integral shackled plastic surround (15) is shown as a segment and the clamping device (16) is shown as being integrally molded from the plastic material 43 200916335 (15). In this regard, the observation of a configuration of two components and the use of various plastic materials or metal fine components, as mentioned in the description of Figure 1, are applicable. Figure 3 shows an exploded partial representation of an example of an electroluminescent element (2) having a substrate (3) and members (6, 7, 8, 9, 1 〇, 5 丨 1). In this exploded partial illustration, an exemplary configuration of an electroluminescent element (2) having a rear substrate (3) and a rear conductive structure (17) is shown. The members (6, 7, 8, 9, 10, 11) are only decomposed in the upper region and in principle they can also be arranged on other edges or on the back 10 of the substrate (3).
