Japanese Patent No. 2723177 Japanese Patent No. 2799966

  In the light emitting decorative body according to Patent Documents 1 and 2, since two layers of a surface protective layer and a transparent adhesive layer are interposed between the transparent electrode of the EL sheet and the decorative layer, the surface protective layer and the transparent adhesive layer However, although it has light transmittance, there is a problem that diffused reflection of light easily occurs and the luminance is lowered.

  The present invention has been made in consideration of such problems, and an object of the present invention is to provide a light emitting decorative body using an EL light emitting element.

  In order to solve the above-described problems, the light-emitting decorative body according to the present invention employs means described in each of the claims.

  That is, the invention is characterized in that a decorative layer having a light transmitting property is laminated at least partially on a transparent electrode of an EL light emitting element via a binder layer having an adhesive property and a light transmitting property.

  In this means, a single binder layer is interposed between the transparent electrode of the EL light emitting element and the decorative layer instead of a plurality of layers.

  According to a second aspect of the present invention, in the light emitting decorative body according to the first aspect, the binder layer has one or both of an insulating property and a water barrier property.

  In this means, the binder layer is provided with necessary insulation and water barrier properties corresponding to the characteristics of the decorative layer.

  According to a third aspect of the present invention, in the light emitting decorative body according to the first or second aspect, the decorative layer includes a plurality of ink layers.

  In this means, the decoration layer is decorated with a plurality of ink layers by a printing means or the like.

  According to a fourth aspect of the present invention, in the light emitting decorative body according to any one of the first to third aspects, the decorative layer includes at least a single metal foil layer.

  In this means, the decoration layer is decorated with at least a single metal foil layer by foil pressing means or the like.

  According to a fifth aspect of the present invention, in the light emitting decorative body according to the first aspect, the EL light emitting element is made of an inorganic material.

  The light emitting decorative body according to the present invention has an effect of preventing irregular reflection of light and increasing luminance because a single binder layer is interposed between the transparent electrode and the decorative layer of the EL light emitting element. is there.

  According to the second aspect of the present invention, since the binder layer is provided with necessary insulating properties and water barrier properties corresponding to the characteristics of the decorative layer, it is possible to avoid the progress of deterioration due to the omission of the surface protective layer of the EL light emitting device. .

  According to the third aspect of the present invention, since the decoration layer is decorated with a plurality of ink layers by a printing means or the like, there is an effect that the decoration property is enhanced by increasing the number of colors.

  Further, since the decoration layer is decorated with at least a single metal foil layer by a foil pressing means or the like, there is an effect that the decorativeness is enhanced by a combination of light transmission and light non-transmission.

  Further, as a fifth aspect of the present invention, in the structure of the light emitting decorative body according to the present invention, by using an EL light emitting element made of an inorganic material, the appearance shape is not only a flat structure but also a curved structure. However, a sufficiently high gas barrier property can be realized while reducing the thickness.

  Hereinafter, the best mode for carrying out the light emitting decorative body according to the present invention will be described with reference to FIGS.

  1 to 3 show a first example of the best mode for carrying out a light emitting decorative body according to the present invention.

  In the first example, the present invention is applied to a light-emitting panel B such as a surface panel attached to the surface of a decorative item A such as a mobile phone or a vehicle instrument panel.

  As shown in FIG. 1, the first example has a structure in which an EL light emitting element 1, a binder layer 2, and a decoration layer 3 are integrated with a panel base material 4.

  In the EL light emitting device 1, a back protective layer 1a, a back electrode 1b, a dielectric layer 1c, a light emitting layer 1d, and a transparent electrode 1e are laminated by printing means or the like. That is, the surface protective layer f of the general-purpose product shown in FIG. 7 is omitted. The back protective layer 1a is made of, for example, medium. The back electrode 1b is made of, for example, carbon or a resin binder ink. The dielectric layer 1c is made of, for example, ink of barium titanate and a fluororesin binder. The light emitter layer 1d is made of, for example, ink of zinc sulfide, copper, or a fluororesin binder. The transparent electrode 1e is made of indium tin oxide (ITO), for example. In the back protective layer 1a, two through holes 1f and 1g for opening the back electrode 1b and the transparent electrode 1e are formed on the outer surface of the back protective layer 1a. The back electrode 1b, the dielectric layer 1c, and the light emitting layer 1d are perforated with one through hole 1g for exposing the transparent electrode 1e on the outer surface of the back protective layer 1a.

  In this EL light emitting device 1, by applying a voltage to the back electrode 1b and the transparent electrode 1e, the light emitting layer 1d can emit light and the transparent electrode 15 side can be used as the light emitting surface.

  The binder layer 2 blocks adhesiveness that exerts an adhesive force on both the transparent electrode 1e and the decorative layer 3 (ink layer 3c) of the EL light emitting element 1 and blocks light emitted from the light emitting layer 1d of the EL light emitting element 1. It has a light transmittance that does not occur. This adhesiveness mainly exerts an adhesive force by adhesion due to leveling (flatness) to both the transparent electrode 1e and the decorative layer 3 (ink layer 3C).

  The binder layer 2 is provided with an insulating property and a water barrier property as necessary in order to supplement the function that the surface protective layer f (see FIG. 7) of the EL light emitting element 1 is omitted. The water barrier property is required for deterioration of zinc sulfide of the light emitting layer 1d of the EL light emitting element 1.

In the decoration layer 3, ink layers 3b and 3c are laminated on both sides of a metal foil layer 3a made of a single layer of aluminum or the like by printing means, foil pressing means or the like based on the panel base material 4.

  The decoration layer 3 is decorated with a combination of light transmission and light non-transmission with the metal foil layer 3a and decorated with multi-coloring with the two ink layers 3b and 3c. Property (designability).

  The panel substrate 4 is made of a sheet or a plate such as acrylic or polycarbonate that retains the shape of the light-emitting panel B.

  In order to manufacture the first example, the binder layer 2 is stacked on the decorative layer 3 stacked on the panel substrate 4 by printing means or the like, and the separately manufactured EL light-emitting element 1 is formed with the transparent electrode 1e as the binder layer 2. Lamination is performed so as to be joined. In addition, as a product of the light emitting panel B, the adhesive bonding layer 5 is laminated on the outer surface of the back protective layer 1a of the EL light emitting element 1, and a release sheet (not shown) is further laminated as necessary. Also in the adhesive bonding layer 5, through holes 5a and 5b corresponding to the through holes 1f and 1g of the EL light emitting element 1 are drilled.

  According to the first example, a single binder layer 2 is interposed between the transparent electrode 1e of the EL light emitting element 1 and the decorative layer 3 instead of a plurality of layers. Therefore, irregular reflection of light does not occur and the luminance increases.

  Further, as shown in FIG. 2, the inverter 7 connected to the power source 6 is built in the article to be decorated A, and the electrode 8 connected to the inverter 7 is provided on the surface to be attached of the article A to be decorated. The light emitting panel B from which the adhesive adhesive layer 5 is peeled off can be joined and attached with one touch in a state where the shape is maintained by the panel base material 4 to emit light. Therefore, it is easy to mount the light emitting panel B.

  In addition, as shown in FIG. 3, it is also possible to form the to-be-attached surface of the to-be-decorated goods A in the groove shape which the light emission panel B can insert and attach.

  4 to 6 show a second example of the best mode for carrying out the light emitting decorative body according to the present invention.

  In the second example, the back protective layer 1a is removed from the EL light-emitting element 1, the binder layer 2 is separated into the first binder layer 2a and the second binder layer 2b, and the EL light-emitting element 1, the binder layer 2, and the decoration are separated. The layered structure of the layer 3 and the panel substrate 4 is improved.

  That is, the second binder layer 2b is common to the binder layer 2 of the first example, and joins the transparent electrode 1e of the EL light emitting element 1 and the decoration layer 3. However, the decorative layer 3 is not laminated on the panel substrate 4, and the outer surface is protected by the overcoat layer 9.

  The first binder layer 2 a has adhesiveness that exerts an adhesive force on both the back electrode 1 b of the EL light emitting element 1 and the panel substrate 4, but emits light by the light emitter layer 1 d of the EL light emitting element 1. Therefore, it is not necessary to have light transmittance without blocking the light. The first binder layer 2a is also provided with insulating properties and water barrier properties as necessary in order to supplement the function that the back surface protective layer 1a of the EL light emitting element 1 is omitted.

  The panel substrate 4 has two through holes 4a and 4b formed on the outer surface for opening the back electrode 1b and the transparent electrode 1e of the EL light emitting element 1.

  In order to manufacture the second example, the second binder layer 2b is stacked on the inner surface of the decorative layer 3 having the overcoat layer 9 stacked on the outer surface by printing means or the like, and the separately manufactured EL light emitting device 1 is transparent. The electrode 1e is laminated so as to be bonded to the second binder layer 2b, the first binder layer 2a is laminated on the panel base material 4 by a printing means or the like, and the decoration layer is first interposed via the second binder layer 2b. The EL light-emitting element 1 bonded to 3 is laminated so that the back electrode 1b is bonded to the first binder layer 2a. In addition, as a product of the light emitting panel B, an adhesive adhesive layer 5 in which through holes 5a and 5b are perforated is laminated on the outer surface of the panel substrate 4, and a release sheet (not shown) is further laminated as necessary. The

  According to the second example, substantially the same operations and effects as the first example are achieved.

  As shown in FIG. 6, also in the second example, it is possible to form the attachment surface of the article to be decorated A into a groove shape into which the light emitting panel B can be fitted and attached.

  As described above, in addition to the illustrated examples, the present invention can be applied to other than the light emitting panel B attached to the surface of the article to be decorated A.

  Furthermore, it is possible to implement even if the panel substrate 4 is slightly curved or has an uneven structure.

<About EL>
Here, EL will be described. In EL display devices using EL, there are inorganic EL panels using inorganic EL elements whose light emitters are made of inorganic materials, and organic EL panels using organic EL elements whose light emitters are made of organic materials.

  Since both of these inorganic EL elements and organic EL elements are deteriorated by moisture, it is indispensable for the EL display device to seal the light emitting element portion for moisture prevention or the like.

  Here, organic solids such as light emitters (organic light emitters) and hole transport layers used in organic EL devices are generally vulnerable to moisture and oxygen, and dark spots (non-light emitting) due to moisture and oxygen present in the device. Part) growth and light transmittance decrease. Therefore, in order to guarantee the reliability of the organic EL element, the EL element must be sealed in order to prevent moisture and oxygen from entering the organic material and the electrode material.

  Moreover, in the sealing method of an organic EL element, for example, a method of metal-sealing the organic EL element together with a hygroscopic material, or a method of providing a glass plate outside the back electrode and enclosing silicone oil between the back electrode and the glass plate Etc. There is also a method of sealing the organic EL element with an organic film having excellent gas barrier properties or a film having an inorganic oxide vapor deposition film.

In addition, as a film (organic film) for sealing an organic EL element, an organic thin film such as polychlorotrifluoroethylene (PCTFE), a physical vapor deposition method such as a vacuum deposition method, a sputtering method, an ion plating method ( PVD method), chemical vapor deposition method (CVD method) such as plasma chemical vapor deposition method, thermal chemical vapor deposition method, photochemical vapor deposition method, etc., and SiO ₂ , Al ₂ on a plastic substrate. A transparent gas barrier film formed with an inorganic oxide film such as O ₃ or MgO is a candidate.

  Here, the sealing material required when the organic EL element is commercialized as a display device requires high gas barrier properties as well as transparency.

  However, regarding an organic film having a current gas barrier property, a gas barrier property effective for sealing an organic EL element has not been realized. For example, when a gas barrier film that is not used for organic EL element sealing is diverted, in order to realize gas barrier properties sufficient for organic EL element sealing, it is necessary to have a considerable film thickness.

  However, from the viewpoint of product design and convenience, there is a demand for thinner display devices. Therefore, it is necessary to realize a high gas barrier property while reducing the thickness.

  Here, according to the structure of the light emitting decorative body according to the present invention as described above, the inorganic EL element is thinned not only in a flat (flat) structure but also in a curved (curved) structure. A sufficiently high gas barrier property can be realized while achieving the above. In addition, since the gas barrier property is good, it can prevent the ingress of moisture and oxygen (high moisture-proof effect), so according to the light-emitting decorative body according to the present invention, dark spots (non-light-emitting portions) can be prevented. The reliability (eg, long life) of the inorganic EL element can be maintained without causing growth or a decrease in light transmittance.

  Therefore, for example, in a keyless entry device 100 that locks (locks) or unlocks (unlocks) a door of an automobile by remote control, when the upper panel is irradiated from the back, according to the prior art, the EL element Since the display device itself using a large scale becomes a large-scale device, the keyless entry device 100 itself is increased in size, causing problems in design and operability, and increasing the manufacturing cost.

  However, if the light emitting decorative body according to the present invention is used, a display device using an inorganic EL element can be integrated with the upper panel via a binder layer, so that the upper panel can be integrated. Compared to products using conventional technology, it can be made thinner, has better design and operability, and can be manufactured at lower cost. Further, when the light emitting decorative body according to the present invention is used, for example, as shown in FIG. 8, the electrode 103 of the upper panel 101 with the display device and the electrode 104 of the lower housing 102 are electrically connected. As described above, the thin keyless entry device 100 can be manufactured by fitting the upper panel 101 with the display device into the lower housing 102.

<About the binder layer>
Next, the binder layer 2 of the light emitting decorative body according to the present invention will be described. For example, a dispersion-type inorganic EL used as a film-like light source requires a base material base (insulating layer) because of its structure and uses a resin material. If it exceeds (for example, R = n), whitening due to so-called stress may occur or break.

  In addition, when applying EL elements to a sheet using screen printing, if a thin sheet is used, the base material of the sheet may be deformed by the force during application in the step of applying ink or light emitter, When air vacuum is used, there is a problem that the sheet itself is deformed and the coating film is not uniform. Here, if the base material of the sheet is deformed or the coating film is non-uniform, unevenness occurs in the light emission of the EL element.

  Here, in the present invention, the binder layer 2 is made of a thermosetting liquid resin such as liquid urethane or epoxy material. By applying and curing such a binder layer 2 on an easily peelable plate or sheet, a current-carrying layer is formed in a sheet shape to form a light-emitting layer-current-carrying layer-urethane layer, and both sides are sandwiched between soft materials. Therefore, it can adhere to and follow a curved surface exceeding a certain curvature (R = n) as compared with a conventional product in which a whitening phenomenon occurs.

  Therefore, the light-emitting decorative body according to the present invention can be used for a curved panel having a curved surface exceeding a certain curvature, which has been difficult in the past, as will be described later in <Application Example>.

  In addition, when a colored sheet is used, if a different color tone is required for the surface color of the two main colors of the EL device when it emits light and when it is not emitting light, use a transparent sheet. It is possible to create a three-dimensional printing design using an intermediate layer having a design surface on both the back surface and the front surface, and a plurality of colors can be expressed.

  In addition, if design printing is performed after the surface insulating layer and conductive layer are created, the printing process of the non-light emitting portion for performing the design printing after printing the shading color on the surface of the same sheet can be eliminated. The surface hardness (depending on the material) is improved, and the surface irregularities can be eliminated and smoothed.

  Epoxy resins and urethane resin materials are used as semiconductor protection and circuit sealing materials, and are also effective as protection for energization layers.

  Also, making the surface irregularities uniform is also effective for the close contact of the electrically conducting layer, and the use of an adhesive for the sheet allows for the elimination of air as a means of preventing oxidation related to the life of the EL. Cold laminating / hot laminating which melts and bonds the resin base material is also unnecessary, and it is possible to eliminate the air layer as the cause of oxidation, thereby contributing to the extension of the service life.

  Epoxy resins and urethane resin materials are also effective in improving water resistance, are not easily hydrolyzed, and are soft and effective in waterproofing rain such as storms and pressure such as wind.

  In addition, printing on the surface is possible, and coloring on the material itself is also possible.
