DISPLAY ASSEMBLIES AND METHODS FOR APPLYING THEM TO VULCANIZED RUBBER ARTICLES FIELD OF INVENTION This description refers to display assemblies and methods for applying them to a vulcanized rubber article. BACKGROUND OF THE INVENTION The use of decals or similar markings on vulcanized rubber articles, such as a tire sidewall portion, is known in the art, for example, in the form of inscriptions and / or designs, for the purpose of adding aesthetic features, markings, or similar characteristics to the vulcanized article bearing them. Such decals, known in the art and adapted for these uses, are constructed in a form intended for temporary rather than permanent service and / or are adapted for application at a point in the manufacture of the vulcanized articles. For example, traditional techniques for establishing tire sidewall markings involve extruding or molding black rubber and frequently adding colored inks that are cured in parallel with the tire during the vulcanization process.This process, while well-established and scaled for the industry, requires significant investment in materials, equipment, and labor, along with considerable waste costs resulting from voids, stains, and other design defects. Furthermore, this technique is extremely limiting in terms of customizable designs due to the molds and dies required to achieve the desired variations, thus severely restricting the availability of this customization to individual customers and even internal clients within the industry. Therefore, it is desirable that display assemblies for use with a vulcanized article be constructed in a way that allows not only variation in the nature of the display itself—for example, the nature of the markings being one or a combination of characters, designs, emblems, and combinations thereof—but also variation in the method of applying them to facilitate application as part of or subsequent to the manufacture of the vulcanized article. Furthermore, it is desirable that such a display assembly be constructed in a way that facilitates its use once applied for an extended period, for example, the lifetime of the vulcanized article. Moreover, it is desirable that such a display assembly be constructed in a way that facilitates such long-term use without sacrificing the integrity and aesthetic appearance of the display assembly. Did I hear? Lfrnn / zznz / B / YiAi SUMMARY OF THE INVENTION Display assemblies, as described herein, are specially constructed for attachment to a vulcanized rubber article to provide a desired display cue, which may be a visual display or a feature that is visually or otherwise detectable. Display assemblies as described herein generally comprise a composite of different layers of material specially designed to provide a desired display cue in a form that will last for an extended period on the vulcanized rubber article. Display assemblies comprise one or more display layers of elastomeric material configured to provide a desired display cue, an intermediate layer formed of an elastomeric material different from that of the one or more display layers, and an adhesive layer, wherein the intermediate layer is interposed between the adhesive layer and the one or more display layers. In one example, the adhesive layer is formed from a material that forms a chemical bond between the display assembly and the surface of the vulcanized rubber article. The display assembly may comprise two display layers, where one display layer is disposed beneath another, and where each display layer is a different color and / or patterned or otherwise configured to provide a desired display cue through interaction. An intermediate adhesive layer may be interposed between one or more display layers and the intermediate layer. If desired, a transparent protective layer may be disposed over one or more display layers, forming an outer surface of the display assembly. The display assembly may comprise a cavity therein that may include an element. Display assemblies as described herein may be affixed to the surface of a vulcanized article by applying an adhesive material to form the adhesive layer. The adhesive layer may be applied to one or both of the surface of the vulcanized article and an underlying surface of the display article. The display assembly is then placed in contact with the surface of the vulcanized rubber article to form an adhesion between the display assembly and the surface. In one example, a template may be used to ensure the placement of the display assembly in a desired arrangement, or a transfer carrier may be used to provide the display assembly in the desired arrangement for placement on the surface. Display assemblies as described herein, are constructed to provide flexibility in the lower qh Lfrnn / zznz / E / YiAi '28' to a cushioning barrier layer '24' layered with an adhesive layer '26' to permanently adhere to the vulcanized rubber article; Figure 3 is a cross-sectional side view of a second illustrative display assembly as described herein, wherein a double display layer embodiment comprises a four-layer assembly '30' having a first display layer '31' as the outer aesthetic display layer that is vulcanized for permanent adhesion to a second display layer '33' that is further vulcanized to a buffer barrier layer '36' layered with an adhesive layer '38' for permanent adhesion to the vulcanized rubber article; Figure 4A is a cross-sectional side view of a third illustrative display assembly as described herein comprising a single display layer with a double-layer adhesive and a four-layer barrier assembly '40' having a layer '48' as the outer aesthetic display layer which is bonded with a cushioning barrier layer '44' which uses a permanent adhesive layer '50' and the barrier layer '44' is layered with another adhesive layer '46' to permanently bond to the vulcanized rubber article. Figure 4B is a cross-sectional side view of a third alternative illustrative display assembly as described herein, comprising double display layers with double-layer adhesive and a five-layer barrier assembly '42' having a layer '45' as the outer display layer which is bonded to a second or intermediate display layer '49' which uses an intermediate adhesive layer '47' and the intermediate display layer is bonded to a buffer barrier layer '51' which is layered with another adhesive layer '53' to permanently bond to the vulcanized rubber article; Figure 5 is a cross-sectional side view of an illustrative fourth display assembly as described herein, comprising a five-layer assembly '50' of the double-layer display modality '52' having a layer '57' as the outer aesthetic display layer that is vulcanized for permanent adhesion to a second display layer '59' that is bonded with a cushioning layer '56' that utilizes a permanent adhesive layer '54' and the barrier layer '56' is layered with another adhesive layer '58' for permanent adhesion to the vulcanized rubber article; Figure 6 is a cross-sectional side view of an illustrative fifth display assembly as described herein comprising a four-layer modality assembly '60' of the double display layer '64' having a layer '62' as a protective overlaminated layer disposed over all or a portion of the display layer(s) '67' and '69' vulcanized to a buffer barrier layer '66' and layered with a permanent adhesive layer '68' for adhesion to the vulcanized rubber article; Figure 7 is a cross-sectional side view of an illustrative fifth display assembly as described herein comprising a multi-layer assembly '70' with cavity '78' having a functional element integrated '79' with the construction of the assembly, wherein the assembly '70' comprises a double display layer '72' with aesthetic layers 80 and 82 that also serve as perimeter layers to the cavity '78', wherein the display layers are vulcanized and bonded to a barrier layer '76' with a permanent adhesive layer '74' and having another permanent adhesive layer '77' for bonding to the vulcanized rubber article; and Figures 8A to 8F are a perspective view of an illustrative method for fixing a display assembly as described herein. DETAILED DESCRIPTION OF THE INVENTION Display assemblies or constructions as described herein are specifically designed to facilitate attachment to a vulcanized article, which may include, but is not limited to, tires, fenders, or any other member or element that is vulcanized or made from vulcanized rubber. Display assemblies as described herein are intended for the purpose of providing a desired aesthetic appearance, product identification, tracking, marking, advertising, providing a desired functional aspect to the vulcanized article, and similar applications to such a vulcanized article.In one example, display assemblies as described herein may comprise one or more elastomeric display layers that provide the desired display image or function, an intermediate barrier layer formed from an elastomeric material, and a curable adhesive layer formed from a material capable of forming a strong bond with a surface of the vulcanized article. Display assemblies as described herein may optionally comprise an adhesive layer interposed between the display layer and one or more of the barrier layers, and may comprise various combinations of one or more display layers, one or more intermediate or barrier layers, and one or more adhesive layers as required by the specific end-use application. Furthermore, display assemblies as described herein may optionally comprise a transparent protective coating or layer disposed over the display layer. Figure 1 illustrates an illustrative display assembly or construction 10 as described herein as attached to a vulcanized article 12. Display assemblies as described herein can be used with a variety of differently configured vulcanized articles, wherein a unifying feature of such articles or attachment substrates is that they are formed from, or have an outer surface comprising, vulcanized rubber. In one example, the vulcanized article may be a rubber tire, wherein the display assembly is configured to adhere to a portion of the rubber tire. In one example, the portion of the rubber tire may be a sidewall 14 of the tire.Although a particular configuration or type of vulcanized rubber, and a particular portion of such article, has been described as being useful as the article or substrate for adhering display assemblies as described herein to it, it shall be understood that the use of display assemblies as described herein is not limited to such types of vulcanized articles and / or a portion thereof, and such is provided for purposes of example and reference. Display assembly 10 is provided in a desired shape or configuration depending on the intended display indication or function, which may be in the form of a letter, number, symbol, design, pattern, logo, badge, or the like, and may be continuous or discontinuous in form depending on the particular end-use application. For example, display assembly 10 may be configured in the shape of a letter, and a number of display assemblies may be used alone or in conjunction with one or more other display assemblies, which may be continuous with each other or separate from one another, to provide a word, term, mark, logo, message, symbol, desired function, or the like on a surface of the desired vulcanized article.For example, display assembly 10 may be configured as a continuous member that is arranged along an entire portion of the vulcanized article, for example, such as a sidewall strip or other continuous form of evidence, or only along a designated partial portion of the vulcanized article. In one example, each display assembly 10 comprises one or more display layers that provide an outer surface of the display assembly that visually provides the display image, cue, or function. The one or more display layers may be formed from an elastomeric material and may be configured to provide a desired display image or cue on the outer surface of the display assembly 10. In one example, the display layer may be constructed to have a desired color, pattern, shape, and / or texture useful for providing a desired display image, cue, or function. In one example, the display layer qh Lfrnn / zznz / B / YiAi may be configured and / or colored and / or patterned to produce a desired display image, cue, or function in conjunction with an underlying barrier layer.For example, the display layer may comprise one or more openings, such as a pattern of openings, and be of one color, while an underlying barrier layer may be of a different color, making it visible through the openings of the display layer to provide the desired display effect or cue on the outer surface of the display assembly. If two or more display layers are used, the different display layers may be configured, colored, textured, and / or patterned differently to combine and provide the overall desired display effect or cue on the outer surface of the display assembly. In one example, each display layer may be configured to have a generally similar shape, e.g., in the shape of a letter, object, or number, where one of the display layers is provided in one color and another of the display layers is provided in a different color, and where the display layers are sized differently, so that when combined together they operate to provide a desired visual display effect. In one example, qh Lfrnn / zznz / E / YiAi may provide a top display layer that has a white color and a bottom display layer below the top display layer may be provided having a black color, wherein the bottom display layer is sized in some way larger than the top display layer to enhance the visual effect provided by the combined display layers. Alternatively, the display layer can be provided as a single layer or with a desired cropped segment, and the desired display image is provided in contrast to another underlying layer of the display assembly, which could be, for example, another display layer or a barrier layer. For instance, using a patterned display layer in one color arranged on top of an underlying display layer or barrier layer of another color can provide a desired cue, such as a barcode or similar identifier used for identification or other purposes. The display assembly 10 is bonded or otherwise attached to a surface of the desired vulcanized article 12. In one example, the display assembly is bonded to the vulcanized article in a manner best described below, which produces a strong and durable bond with it, for example, to facilitate the attachment of the display assembly to the vulcanized article for an extended period of time, which may be the service life of the vulcanized article. In one example, the display article is chemically bonded to the vulcanized article. In one example, the display assembly may be configured to match the contour or other surface geometry or surface feature of the vulcanized article with which it is to be used.For example, if the vulcanized item is a rubber tire sidewall surface, display assemblies as described herein may be configured to match the color of the outer wall surface to promote a desired optimum fit with it when attached to it. Figure 2 illustrates a first illustrative display assembly 20 as described herein, comprising a portion of the display assembly 20 attached to a vulcanized rubber article, a display layer 22, an intermediate barrier layer 24, and an adhesive layer 26. As noted above, the display assembly 20 is configured to have a shape and size as desired for a particular end-use application. In one example, the display layer 22 is provided in the form of a single layer of elastomeric material that may be colored, patterned, and / or textured as desired to provide a desired display image or indication visible on the outer surface of the display assembly 20.In an illustrative manner, elastomeric materials suitable for forming the display layer 22 include, but are not limited to, vulcanized rubber, natural rubber, SBR, nitrile rubber, neoprene rubber, elastomeric rubber-based inks that possess aesthetically pleasing and functional properties, high elongation, UV resistance, chemical resistance, and abrasion resistance, and combinations thereof. For example, depending on the size and configuration of the display assembly 20, the display layer 22 can have a thickness greater than approximately 0.01 mm, ranging from approximately 0.01 to 10 mm, 0.05 to 5 mm, 0.1 to 3 mm, and in one particular example, approximately 0.4 mm. In one example, the barrier intermediate layer 24 is fixed or adhered along a lower surface 28 of the display layer 22. In another example, the intermediate layer 24 extends along and covers the entire lower surface 28 of the display layer. Alternatively, the intermediate layer 24 may extend along a partial portion of the lower surface of display layer 28, which is less than the entire portion and more than a majority or 51% of the total area of ​​the lower surface of display layer 28.In this example, the intermediate barrier layer 24 is formed from a material capable of providing cushioning, elastomeric expansion, and / or contraction properties compatible with the vulcanized rubber article to which the display assembly is to be attached, and a desired degree of conformability between the adjacent surfaces of the display layer and the outer surface of the vulcanized rubber article (to maximize the surface contact area between the display assembly and the vulcanized rubber article). Furthermore, in the example illustrated in Figure 1, it is desired that the intermediate layer 24 be formed from a material capable of chemically bonding to the display layer 22. It is also desired that the barrier intermediate layer 24 be formed from a material capable of acting as a barrier to minimize or prevent the migration of any unwanted constituents from the adhesive layer 26 and / or the vulcanized rubber article that might otherwise damage or degrade the image and / or design feature provided by the display layer 22. In one example, the intermediate layer is formed from an elastomeric material. Elastomeric materials useful for forming the intermediate layer 24 include, but are not limited to, rubber, vulcanized natural rubber, nitrile rubber, polyurethane, or comparable materials that have high elongation, conformability, and chemical resistance to notable mold release agents common in vulcanized tire rubber, and combinations thereof.In one example, depending on the size and configuration of display assembly 20, the thickness of the intermediate layer 24 is desired to be sufficient to allow it to function as described above. The exact thickness of the intermediate layer is understood to vary depending on the specific type of material selected for the intermediate layer, as well as the particular end-use application. For instance, the intermediate layer 24 might be thicker than approximately 0.008 mm, ranging from approximately 0.008 mm to 10 mm, approximately 0.01 mm to 5 mm, approximately 0.1 mm to 1.5 mm, and in one particular example, approximately 0.5 mm. The adhesive layer 26 is to be made of a material capable of forming a heat-activated, chemically bonded, or otherwise permanently bonded, bond with the vulcanized rubber article. In one example, the bond is to have a service life equal to that of the vulcanized rubber article to provide a permanent bond, allowing the display assembly to function for the lifetime of the vulcanized article. The specific material used for the adhesive layer may vary depending on the particular application environment of the display assembly, for example, in a manufacturing environment where the vulcanized article is being produced, or in a customer environment subsequent to the production of the vulcanized article.In one example, in a method where the display assembly is being attached to the vulcanized rubber article at the point where the article is being manufactured, the adhesive layer may be formed from a material capable of forming the desired chemical bond or vulcanizing to it under elevated temperature conditions, such as heat-activated adhesives. Such materials include, but are not limited to, thermoplastic and thermoset adhesives, thermally vulcanizing cements commonly used in retreading applications, water-based or solvent-based polymer polyurethane adhesives, and combinations thereof. Such an application may also require some degree of elevated pressure to be applied to the display assembly during bonding by the adhesive layer. For example, such elevated pressure may be in the range of approximately 20.64 to 68.94 kPa (3 to 100 psi). In an illustrative example, such as one where the display assembly is being attached to a customer-vulcanized rubber article or similar at a point subsequent to the manufacture of the vulcanized rubber article (qh Lfrnn / zznz / B / YiAi), the adhesive layer may be formed from a material capable of forming the desired chemical adhesion or vulcanizing to it under ambient temperature conditions, for example, by chemical reaction rather than being activated by heat. Such materials include, but are not limited to, chemical cements commonly used in retreading applications, cyanoacrylate, epoxies, rubber-based acrylic pressure-sensitive adhesives, and combinations thereof. Each application may also require that some degree of elevated pressure be applied to the display assembly during adhesion by the adhesive layer. In one example, such elevated pressure may be in the range of approximately 20.64 to 68.94 kPa (3 to 10 psi). In one example, depending on the size and configuration of the display assembly 20, the thickness of the adhesive layer 26 is desired to be sufficient to allow it to function as described above. The exact thickness of the adhesive layer is understood to vary depending on the specific type of material selected for the adhesive layer, as well as the particular end-use application. For instance, the adhesive layer 26 might be thicker than approximately 0.006 mm, ranging from approximately 0.006 mm to 0.5 mm, 0.01 mm to 0.3 mm, 0.02 mm to 0.1 mm, and in one particular example, approximately 0.04 mm. qh Lfrnn / zznz / E / YiAi In one example, the display assembly described above and illustrated in Figure 2 can be made by bonding the display layer and intermediate layer together and then subjecting them to elevated temperature and / or pressure vulcanization conditions. After this time, the adhesive layer can be combined with these layers, for example, at the point of applying the display assembly. Although the illustrative display assembly shown in Figure 2 has been described as comprising three separate and distinct layers, it is understood that one or both of the display layer or the adhesive layer are configured to include a barrier composition at an interface between them that can operate to provide the barrier properties described above, thereby avoiding the need to use three separate and distinct layers for the display assembly. Figure 3 illustrates a second illustrative display assembly 30 as described herein comprising, moving a surface portion of the display assembly 30 to a portion fixed to a vulcanized rubber article, a display layer 32, an intermediate or barrier layer 36, and an adhesive layer 38. Unlike the example illustrated in Figure 2 and described above, the display layer 32 in this example is formed from two or more different display layers, e.g., a first or upper display layer 31 and a second or lower display layer 33. In this configuration, each display layer can be sized, shaped, patterned, colored, and / or textured differently from the others to provide a desired display cue when combined. For example, the first display layer, 31, might be white and a certain size, while the second display layer, 33, might be black and slightly larger to provide a visual cue. This is just one example of how different display layers, 31 and 33, can be used together to provide a desired display cue.In another example, as noted earlier, the first display layer may be one color and have one or more openings cut into it, and the second display layer is a different color so that this color is visible through the openings to provide a desired visual cue on the surface of the display assembly. A few examples of how the first and second display layers can be used to provide a desired display cue are provided for illustrative and reference purposes, and it will be understood that all such variations will fall within the scope of the display assemblies as described herein. qh Lfrnn / zznz / B / YiAi Also, although an example comprising two display layers has been described, it will be understood that display assemblies as described herein may comprise more than two display layers depending on the particular display cue desired for the particular end-use application.The display layers 31 and 33, as well as the intermediate layer 36 and the adhesive layer 38, can each be formed from the same types of materials described above for the first examples. In one example, the display layers 31 and 33 can have the same thickness as described above, so that the overall thickness of the display layer 32 is generally greater than that of the first examples described. However, the thickness of the display layer 32 can also be less than or equal to the thickness of the first examples described to meet the requirements of a particular function or aesthetic preference.As noted above for the illustrative display assembly in Figure 2, the illustrative display assembly illustrated in Figure 3 may alternatively contain a display layer or adhesive layer configured having a barrier composition at an interface, to avoid the need to obtain desired barrier properties through a separate and distinct barrier layer. In one example, the display assembly described above and illustrated in Figure 3 can be made by joining the display layers and the intermediate layer together and then subjecting them to vulcanization conditions of high temperature and / or pressure, after which time the adhesive layer can be combined with it, for example, at the point of applying the display assembly. Figure 4A illustrates a third illustrative display assembly 40 as described herein comprising, moving from a surface portion of the display assembly 40 to a portion fixed to a vulcanized rubber article, a display layer 48, an intermediate adhesive layer 50, an intermediate barrier layer 40, and an adhesive layer 46. The main difference between this second illustrative display assembly 40 and the one previously described and illustrated in Figure 2 is the presence and use of an intermediate adhesive layer 50 interposed between the display layer 48 and the intermediate or barrier layer 44.The presence of such an intermediate adhesive layer 50 in this second example operates to provide a higher degree of adhesion between the display layer 48 and the intermediate layer 44, and may also operate to provide an extra degree of barrier protection against the migration of any unwanted constituent from the intermediate layer 44, adhesive layer 46, and / or the vulcanized rubber article to which the display assembly is attached. The materials used in this second example for the display layer 48, intermediate layer 44, and adhesive layer 46 can be selected from the same types of materials described above for the first two examples. The thickness of the display layer 48, intermediate layer 44, and adhesive layer 46 can also be the same as that described above for the first two examples. The intermediate adhesive layer 50 is formed from a material capable of forming an adherent bond between a lower surface of the display layer 48 and a surface of the intermediate barrier layer 44, and optionally acts as a barrier to minimize or prevent the migration of any unwanted constituents in the display layer 48. In one example, the intermediate adhesive layer 50 is formed from a thermoset adhesive. Thermoset adhesives suitable for forming the intermediate adhesive layer 50 include, but are not limited to, thermally vulcanizing cements common in retreading applications, water-based or solvent-based polyurethane adhesives, epoxies, and combinations thereof.In one example, depending on the size and configuration of the display assembly 50, the thickness of the intermediate adhesive layer 50 is described as being sufficient to allow the intermediate adhesive layer to function as described above. The exact thickness of the intermediate adhesive layer is understood to vary depending on the specific type of material selected for the display layer and the intermediate layer, as well as the particular end-use application. In one example, the intermediate adhesive layer 50 may be thicker than approximately 0.006 mm, ranging from approximately 0.006 mm to 0.5 mm, approximately 0.01 mm to 0.3 mm, and in one particular example, approximately 0.025 mm. In one example, the display assembly described above and illustrated in Figures 4A and 4B can be made by bonding the display layer, the intermediate adhesive layer, and the intermediate layer together and then subjecting them to elevated temperature and / or pressure vulcanization conditions. After this time, the adhesive layer can be combined with these layers, for example, at the point of application of the display assembly. Although the illustrative display assembly shown in Figure 4A has been described as comprising four separate and distinct layers, it is understood that one or more of the display layer, intermediate adhesive layer, barrier layer, or adhesive layer can be configured as a composite having properties of another layer to reduce the total number of separate and distinct layers used to fabricate the display assembly.For example, the intermediate adhesive layer can be configured with a barrier composition along an interface with the adhesive layer, thus avoiding the need for a separate barrier layer. Alternatively, the barrier layer can be configured with an adhesive composition on one or both of its surfaces to avoid the need for one or more separate adhesive layers. These are just a few examples of how composite compositions can be used in such multi-layered display assemblies to reduce the total number of separate material layers used while still providing all the desired properties described. Figure 4B illustrates an illustrative display assembly 42 that is somewhat similar to that illustrated in Figure 4A, as it comprises a display layer 45 on a top surface and an intermediate adhesive layer 47 beneath the display layer. However, in this particular example, the display assembly 42 includes a second, or intermediate, display layer 49 that is interposed between the intermediate adhesive layer 47 and the barrier layer 41, and similarly, in the third example, an adhesive layer 53 is disposed beneath the barrier layer. A feature of such a construction is the ability to configure the top display layer 45—for example, by shape, size, and / or pattern of openings or the like—to reveal at least a portion of the intermediate display layer 49 to provide the desired display indication.Also, in such an example, a subassembly consisting of the adhesive layer 53, barrier layer 51, and intermediate display layer 49 can be made and combined in the manner described above and adhered to the desired substrate portion, for example, a vulcanized rubber article. After such a subassembly has been affixed to the desired substrate, the top display layer 45 can then be affixed to it using the intermediate adhesive layer 47. The ability to construct the display assembly in this manner, using a subassembly and subsequently applying the display layer, adds flexibility by allowing the desired display layer to be provided after a portion of the assembly has already been installed on the substrate. It also allows the subassembly to be manufactured and kept in stock as the standard subassembly for a variety of different types of top display layers.An example of such a display assembly may include white walls, red walls, and other colored walls or other desired type of indication that can now be selected and applied after the standard stock subassembly has been fixed to the substrate. Figure 5 illustrates a fourth illustrative display assembly 55 as described herein comprising, moving from a substrate portion of the display assembly 55 to a portion fixed to a vulcanized article, a display layer 52, an intermediate adhesive layer 54, an intermediate barrier layer 54, and an adhesive layer 58. As in the example illustrated in Figure 3 and described above, the display layer 52 in this example is formed from two or more different display layers, for example, a first or upper display layer 57 and a second or lower display layer 59. As in the example illustrated in Figure 4 and described above, the display assembly 50 comprises an intermediate adhesive layer 54 that is interposed between the display layer 52 and the intermediate barrier layer 56. The intermediate adhesive layer 54 operates in the same way as described above for the example illustrated in Figure 4A, to provide a higher degree of adhesion between the display layer 52 and the intermediate barrier layer 52, and can be formed from the same materials and have the same layer thickness as that described above for the example illustrated in Figure 4A. In one example, display assembly 50 can be made by joining the display layer, the intermediate adhesive layer, and the intermediate layer together and then subjecting them to vulcanization conditions of high temperature and / or pressure, after that time the adhesive layer can be combined with these, for example, at the point of applying the display assembly. Figure 6 illustrates an illustrative fifth display assembly 60 as described herein, comprising a portion of the display assembly 60 moved to a portion fixed to a vulcanized article, a protective layer 62, a display layer 64 (comprising an upper display layer 67 and a lower display layer 69), an intermediate barrier layer 66, and an adhesive layer 58. A feature of this example is the presence of a protective layer 62 disposed over the display layer, wherein the protective layer is formed of an optically transparent material and can be used to enhance and / or protect the display layer from external elements that may damage or otherwise degrade the services provided by the display layer, thereby improving the service life of the display assembly.Although the protective layer has been described in the context of being used with the particular display assembly construction as illustrated in Figure 6, it shall be understood that the protective layer may be used with any and all display assemblies as described herein. In one example, the protective layer may cover the entire surface of the underlying display layer, or display layers if the display assembly comprises more than one display layer, or a partial portion of the display layer depending on the particular display indication and / or the particular end-use application. Materials suitable for forming the protective layer are preferably elastomeric, for example, having the same degree of flexibility or elasticity as that of the underlying display layer, and may be selected from materials including, but not limited to, polyurethane, vinyl, polyethylene terephthalate, rubber-based elastomeric inks, and combinations thereof.In one example, depending on the size and specific configuration of the display assembly, the protective layer thickness should be sufficient to allow it to function as described above. The exact thickness of the protective layer is understood to vary depending on the specific type of material selected for the protective layer, as well as the particular end-use application. For example, the protective layer might be thicker than approximately 0.006 mm, ranging from approximately 0.006 mm to 0.3 mm, approximately 0.01 mm to 0.2 mm, and in one particular example, approximately 0.025 mm. Figure 7 illustrates a sixth illustrative display assembly as described herein, comprising a display assembly surface portion 70 attached to a vulcanized article, a display layer 72, an intermediate adhesive layer 74, an intermediate barrier layer 76, and an adhesive layer 77, wherein a cavity 78 is disposed within the assembly for the purpose of incorporating an element or object 79 therein. As in the example illustrated in Figure 5 and described above, the display layer 72 in this example is formed from two or more different display layers, for example, a first or upper display layer 80 and a second or lower display layer 82. A feature of this particular modality is the presence of a cavity 78 formed in the display assembly 70 to accommodate the placement of an element or object 79 therein. For reference purposes, a display construction somewhat similar to that illustrated in Figure 5 was used to describe the cavity feature, and it is understood that display assemblies as described herein, comprising cavities, may be represented by having other display assembly constructions as described herein. In this example, the cavity is formed within the second display layer 82 and the intermediate adhesive layer and is configured to accommodate a desired item or object. This item or object can be any type of rigid or non-rigid, passive or non-passive, functional or non-functional item that may be useful for inclusion in the display assembly. Examples of the types of items or objects that can be accommodated in the cavity include RFID elements, GPS elements, lighting elements such as LEDs or similar, and the like. In one example, the cavity is configured within the construction to provide an area capable of accommodating such an item or object without damaging it, and without causing damage to the display itself during use of the vulcanized rubber item to which it is attached.In the example illustrated in Figure 7, the cavity is positioned beneath the first display layer 80, and if desired, the first display layer may comprise one or more openings for the purpose of displaying a portion of the object or element disposed within the cavity. It is understood that display assemblies comprising a cavity as described herein may include the cavity positioned differently, for example, formed with one or more different assembly layers, than those illustrated in Figure 7, depending on the particular display assembly, the particular cavity configuration, the particular element or object disposed within the cavity and its intended use and / or function, and / or the particular end-use application of the vulcanized article. Although the cavity feature of display assemblies has been described with reference to particular examples and illustrations, it is understood that display assemblies as described herein may be constructed with the cavity positioned differently than described or illustrated. For example, the design assembly may be configured with the cavity offset along an outer portion of the assembly, which may be a display layer, in which case an element disposed within the cavity could be viewed from outside the display assembly. An example of such an assembly might be one where a lighting element is disposed within the cavity for the purpose of providing illumination or a similar illuminated visual effect outside the display assembly, visible from outside the vulcanized article.In such an example, the cavity may be open and exposed to the external environment, or a layer of transparent or similar material may optionally be placed over it. This is merely an example provided to illustrate how the cavity may be positioned differently within the display assembly to enable a desired function or purpose. Although display assemblies as described herein have been indicated by reference and illustration as having certain aspects and / or characteristics, it shall be understood that display assemblies that meet the general construction parameters as described herein and that have additional elements are intended to be within the scope of display assemblies as covered herein. For example, while display assemblies may be configured to provide a desired display indication or similar through the shape, design, configuration, or similar of one or more display layers, display assemblies as described herein may be configured to provide a desired display indication through the use of printed, marked, or other features that may be included within or on the display area.For example, the display assembly may comprise a desired display cue provided in the form of a symbol, ink letter, or other marker feature or object disposed upon or within the display layer; that symbol, letter, or other marker feature or object may be a mark, logo, or the like. Display assemblies as described herein may have a different overall thickness depending on the particular construction features within the display assembly. For example, the display assembly may have an overall thickness, as measured from a top surface of the display assembly (adjacent to the display layer or protective layer) to a bottom surface (adjacent to the adhesive layer), of approximately 0.0025 mm, from approximately 0.0025 mm to 10 mm, from approximately 0.01 mm to 5 mm, approximately 0.1 mm to 3 mm, and in one particular example, approximately 0.4 mm. It is understood that the exact thickness of the display assembly may and will vary depending on the specific construction of the display assembly and / or its intended application. Display assemblies as described herein can be constructed to suit different conditions for applying the display assembly to a vulcanized rubber article, for example, to suit application during the manufacture of the vulcanized rubber article, or to suit application after the vulcanized rubber article has been made. In one example, display assemblies can be affixed to a surface of a vulcanized rubber article, for example, a tire sidewall surface, by a reaction that may include, but is not limited to, heat and / or pressure and / or chemical adhesion to provide a desired aesthetic appearance in the form of a desired visual cue, such as inscription and / or other objects, shapes, or designs, and / or functional use, such as with barcoding or RFID technology, capable of withstanding the tire manufacturer's recommended life cycle.For example, the element or object arranged within the cavity and attached to the vulcanized article via the display assembly, as described herein, may have programmable functionality with compatibility, such as RFID read / write capability, a programmable circuit board / system that can control a device such as a lighting element like an LED in a predetermined manner. Such functionality may be inherent to the element arranged in the cavity or may be controlled by a separate component, either wired or wirelessly connected, for example, via Bluetooth, radio-controlled, or other frequency-based connection. In one example, the cavity may be configured within the display assembly to accommodate a lighting element here, such as one or more LEDs there, so that the display assembly emits light that can be seen by someone viewing the vulcanized article.In one example, the lighting element can be controlled to provide desired illumination. In an illustrative application method, the desired or target surface of the vulcanized rubber article is cleaned to remove any dirt, oil, debris, or other foreign matter or contaminants that could interfere with forming a desired bond with the display assembly. A suitable cleaning solution or preparation agent may be used for this purpose. For example, such a cleaning solution may be selected from, but not limited to, the group of organic or inorganic solutions such as acetone or similar substances. The cleaning solution may be applied and used to clean the surface using a cloth or similar material.In one example, it may be desired to further treat the surface by roughening it through the use of an abrasive medium such as sandpaper or the like until the surface exhibits a rough texture, and then clean the treated surface, for example, with the cleaning solution, to ensure that it is free from any surface residue from the treatment process. In certain applications, it may be desirable to use a template or mold to properly / precisely position the display assembly on the surface of the vulcanized rubber article. For example, when applying a series of display assemblies to a tire sidewall surface to provide a desired sequence of letters, numbers, and / or designs, a template or mold can be used to ensure that the display assemblies are placed at an appropriate spacing and / or location along the sidewall surface. The template can be provided in the form of a semi-rigid material such as paper, plastic film, or similar material that can be applied to the target surface. The template can be removably affixed to the target surface or held in place manually.In one example, the template or mold comprises a pressure-sensitive adhesive backing and is prepared for bonded placement against the target surface by removing a carrier sheet covering the adhesive and pressing the template into contact with the target surface in the desired position to ensure proper adhesion, specifically around the cutout areas in the template. In the example where a template or mold is used, the steps of treating the target surface by sanding or similar means and then cleaning the treated surface are preferably performed after the template has been placed in position, thereby limiting the area of ​​the target surface being prepared to only that exposed by the cutout areas of the template. Alternatively, instead of using a separate template for the purpose of applying the display assembly in a desired arrangement, the displacement assembly may be configured having a transfer carrier adhered to a top surface of the display assembly, wherein the display assembly is positioned over the transfer film in a desired arrangement for placement on the target surface without the use of a template to provide a visual display having the desired arrangement. A desired adhesive material, selected from those described above, is applied to the treated surface by suitable means, such as spraying, rolling, brushing, or similar methods, to form a desired thickness of adhesive layer to receive the display assembly. In the example where a template is used, the adhesive is applied to the cut-out section(s), and the mold is removed before the adhesive is applied to avoid difficult mold removal. Alternatively, or in addition to the adhesive application method described above, the adhesive can be applied to the underside of the display assembly, which is then applied to the target surface. In one example, the adhesive, once applied to the target surface, is left to dry for a predetermined period of time. The amount of time can and will vary depending on the specific type of adhesive used. In this example, the adhesive used is Heavy Duty Blue Vulcanizing Fluid by Tech International, and it is left to dry for approximately 20-30 minutes. Once the adhesive has dried for the predetermined time, the display assembly is placed onto the adhesive layer.In one example, qh Lfrnn / zznz / E / YiAi, the display assembly is pressed into contact with the adhesive layer and the target surface using a stitching tool. Moderate pressure is applied to the display assembly as the stitching tool is rolled over the entire surface area of ​​the display assembly to ensure complete adhesion and bonding between the display assembly and the vulcanized rubber article via the adhesive layer. In the example where a transfer carrier is used instead of a template, once the display assembly is applied to the target surface and adhered, the transfer carrier is removed from the display assembly, having served its purpose of providing the display assembly in a desired shape, configuration, or arrangement on the target surface. In one example, it is desired that the applied display assembly be allowed to cure for a predetermined amount of time before the vulcanized rubber article is put into use. For example, when the article is a tire sidewall, it is desired that the display assembly be allowed to cure for at least 8 hours before the vehicle comprising the tire or tires is operated. Ideally, in another example, it is desired that the display assembly be allowed to cure for 24 hours before the vulcanized article, in the form of tires, is operated. qh Lfrnn / zznz / B / YiAi In another illustrative method, display assemblies as described here can be applied to a desired vulcanized rubber article at the point of manufacture. In one example, where the vulcanized rubber article is a tire, display assemblies can be applied in a manner similar to that described above, with one difference being that the adhesive material can be provided in the form of a heat-activated material. In this case, once the adhesive material is applied to the target surface, heat is used to cause the display assembly to adhere to it. In such an example, pressure can also be applied by suitable machinery as the adhesive material cures to ensure that the desired adhesion occurs between the vulcanized rubber article and the desired assembly. Although the display assemblies and the method for applying them as described herein have been presented with respect to the modalities described and illustrated, it is understood that the description will not be limited to those alternatives and modalities described. It is hereby stated that, as of this date, the best method known to the applicant for putting the aforementioned invention into practice is the one that is clear from the present description of the invention.
