Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of organic light emitting diode (OLED) devices, and more particularly to modular OLED devices. [Prior Art] Organic LEDs (OLEDs) have several attractive features, such as excellent visual appearance, diffused distribution of light sources, extremely thin or even flexible, choices for transparency, mirroring or black when power is off, and Almost full 2D degrees of freedom in shape. These characteristics make it ideal for signage applications where illuminating letters and graphic symbols of different sizes and colors are used to attract consumers. In this field of application, OLED devices of different sizes and shapes are required depending on the consumer's request. However, the manufacture of such OLED devices is difficult and expensive, especially for larger sizes. SUMMARY OF THE INVENTION One object of the present invention is to provide a custom OLED that is also of a larger size in an easy, convenient, and inexpensive manner. This object is achieved by a plurality of OLED devices and a collection of interfaces for electrically contacting the OLED devices, wherein each OLED device is independently encapsulated, and wherein the interface is adapted to contact different types of encapsulated OLED device. Accordingly, the present invention allows OLED devices of different sizes and forms to be formed by combining a plurality of smaller OLED devices that are themselves encapsulated (i.e., sealed). This means that, in contrast to prior art devices, 138702.doc 201002140, according to the present invention, each OLED device of the set is independently a complete OLED, making it possible to combine these single OLED devices in a customized manner. This means that the present invention is directed to a composite OLED device that is comprised of a plurality of OLED segment devices that can be laminated to a transparent structured interconnect substrate. The OLED segment devices, which may have the form of characters, constitute a collection of building blocks. In combination with individual substrate structuring (e.g., by laser stripping by laser), it is possible to produce OLED devices of any desired size and shape. The composite OLED device is ready to be laminated to any target substrate (e.g., a glass plate). Lamination avoids expensive standard OLED fabrication processes in which only one portion of the entire substrate area is deposited and a new shade mask is required for each design change. Lamination and structuring can be easily performed by standard equipment. In accordance with a preferred embodiment of the invention, the OLED device is laminated to a transparent interconnect substrate that acts as an interface. In this case, it is particularly preferred that the transparent interconnect substrate is composed of polyethylene terephthalate, polyethylene naphthalate, polyether sulfone, polyimide, glass, ceramic, metal, semiconductor or At least one of the combinations is made. The interconnect substrate layer can serve as an additional protective layer to extend the life of the OLED segment device. In addition, according to a preferred embodiment of the present invention, the transparent interconnect substrate comprises a transparent electrode composed of at least a conductive polymeric material, a transparent conductive oxide and a metal (especially indium-tin-oxide, zinc-indium). - oxide, ZnO, Ga-In-Sn-O, Sn 〇 2, Zn-In-Sn-0, Ga-In-O, gold, silver, aluminum, lanthanum, nickel, chromium or a combination thereof to make. Moreover, in accordance with a preferred embodiment of the present invention, the transparent interconnect substrate comprises a 138702.doc 201002140 cladding layer. In this case, it is particularly preferred that the electrically conductive layer comprises at least two regions which are used to electrically insulate the regions from each other by a gap. Preferably, at least one of the encapsulated printing devices is disposed across the gap. It is estimated that the OLED device is placed over the gap and the plurality of OLED devices are connected in parallel. This ensures the same brightness for all shapes with the application of a voltage. ‘The preferred methods of structuring are lasers (4) and (4). Other preferred methods include (.): or lamination of an outer conductive layer (such as the one that can be used for the interconnection of individual segments): the contact between the carrier substrate and the 〇LED segment device is preferably via a conductive adhesive, super The sound wave is welded and the like is completed. According to another preferred embodiment of the present invention, an additional layer of electrically conductive material is provided as a bus bar. Thus, as appropriate, low ohmic bus bars can be used to improve the brightness uniformity of the various OLED segments. The bus bar is an additional layer of highly conductive material such as Ming, copper, silver, and the like. The high reflectivity and mirror-like appearance of a small strip of inscription, copper strip or silver strip can be preferably used. C The opacity of the bus bar structure is used as an agricultural feature. Furthermore, it can be used to hide the contact of the segment/carrier substrate. & Jiadi laminates the film & $ and optional bus bar components to the busbar on the structured ugly board to be patterned onto the target substrate. This can be done using standard techniques. For layer waste, it is preferred to use a pressure/heat/ultraviolet activating adhesive. The resulting two-layer device can be directly laminated to a target substrate (e.g., a panel). Optionally, in accordance with a preferred embodiment of the present invention, additional overlays can be used to encapsulate the OLED segments. [Embodiment] 138702.doc 201002140 These and other aspects of the present invention will be apparent from the embodiments described hereinafter. 1 shows a plurality of OLED devices 1 and a collection of interfaces 2 for electrically contacting the OLED devices 1 in accordance with a preferred embodiment of the present invention. According to this preferred embodiment of the invention, the OLED devices 1 are themselves encapsulated and subsequently laminated to the interface 2. The interface 2 is made of a structured carrier substrate 3 having a conductive layer 4 of conductive material. A stack of LED devices 1 along with its segments is shown in greater detail in FIG. The OLED segment stack includes an upper barrier layer 5, a cathode layer 6, an organic layer 7, an anode layer 8, a lower barrier layer 9, and a transparent flexible substrate 10 from top to bottom (for example, Polycrystalline amine). As further seen in Figures 3 and 4, the collection comprising the 〇led device 1 can be laminated to the glass sheet stack in different ways. Although the assembly is directly laminated to the glass sheet and covered by a PVB foil 12 according to the embodiment shown in FIG. 3, an interlayer pVB foil j 3 is used for the embodiment according to FIG. This collection was laminated to a glass plate i1. Further, a collection of the 〇led device 1 having a character shape can be seen from Fig. 5. According to this preferred embodiment of the invention, the gates of an anode 14 and a cathode 15 have a gap 16. The sub-shaped OLED device 1 is placed across the gap 16 and electrically connected to the anode 14 and the cathode 15 by means of a contact 17 contacting the anode 14 and a contact 18 contacting the cathode. It can be seen that this embodiment can be modified such that a low ohmic metal strip 19 as a bus bar is provided for contacting the single-turn LED device i. These low ohmic bus bars 1 9 provide improved brightness uniformity 138702.doc 201002140 in these 〇 L E D devices. The bus bar 19 is made of an additional layer of highly conductive material such as aluminum, copper or silver. The opacity of the bus bar 19 is used as a decorative feature by the high reflectivity and mirror-like appearance of the small metal strip. In addition, it is used to hide the segment/carrier substrate contacts (i.e., now invisible contact points 丨7, 丨8). A cross-sectional view of this configuration with laminated bus bars 9 can be seen from Figure 7.
