Description

Modular OLED device
FIELD OF THE INVENTION
The invention relates to the field of OLED devices, and especially to modular OLED devices.
BACKGROUND OF THE INVENTION
Organic LEDs (OLEDs) have several attractive features, such as great visual appearance, diffuse distributed light source, extremely thin or even flexible, options for transparency, mirror-like or black when off and almost complete 2D freedom in form. These properties make them ideally suited for signage applications, where luminating letters and graphic symbols of different sizes and colors are used to attract customers.
In this application area OLED devices of different size and shapes are required depending on customer requests. However, especially for bigger sizes, manufacturing of such OLED devices is difficult and costly.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a possibility for customized OLEDs, also in bigger sizes, in an easy, convenient and inexpensive way.
This object is achieved by a set of multiple OLED devices and an interface for electrically contacting the OLED devices, wherein each OLED device is separately encapsulated, and wherein the interface is adapted for contacting different types of encapsulated OLED devices.
Accordingly, the invention allows for composed OLED devices in different sizes and forms by combining multiple smaller OLED devices which are encapsulated, i.e. sealed, by themselves. This means that in contrast to prior art devices, according to the invention, each OLED device of the set is a complete OLED on its own, making it possible to combine these single OLED devices in a customized fashion. This means that the present invention is about a composite OLED device consisting of a plurality of OLED segment devices which can be laminated onto a transparent structured interconnect substrate. The OLED segment devices, which can have the form of glyphs, constitute a set of building blocks. In combination with an individual substrate structuring, e.g. by laser ablation, it is possible to create OLED devices of any desired size and shape. The composite OLED device is ready to be laminated on any target substrate, e.g. a glass plate. Lamination avoids an expensive standard OLED manufacturing process where only a fraction of the whole substrate area is deposited and new shadow masks are required for each design change. The lamination and structuring can be done easily with standard equipment.
According to a preferred embodiment of the invention, the OLED devices are laminated onto a transparent interconnect substrate, which acts as the interface. With respect to this, it is especially preferred that the transparent interconnect substrate is made from at least one of polyethylene terephthalate, polyethylene naphthalate, polyether sulfone, polyimides, glass, ceramics, metals, semiconductors, or a combination thereof. The interconnect substrate layer may serve as an additional protective layer to extend the lifetime of the OLED segment device.
Further, according to a preferred embodiment of the invention, the transparent interconnect comprises a transparent electrode which is made of at least conductive polymeric materials, transparent conductive oxides and metals, especially indium-tin-oxide, zinc-indium-oxide, aluminum-doped ZnO, Ga- In-Sn-O, SnO2, Zn-In- Sn-O, Ga-ln-0, gold, silver, aluminum, iridium, nickel, chromium, or a combination thereof.
Furthermore, according to a preferred embodiment of the invention, the transparent interconnect substrate comprises a conductive layer. With respect to this, it is especially preferred that the conductive layer comprises at least two areas separated by a gap for electrically insulating the areas from each other. It is preferred that at least one encapsulated OLED device is placed across the gap. Preferably, multiple encapsulated OLED devices are placed across the gap and these multiple OLED devices are connected in parallel. This ensures the same brightness for all shapes in case a constant voltage is applied.
Preferred structuring methods are laser ablation and etching. Further preferred methods include printing or lamination of additional electrically conductive layers such as aluminum which can be used for interconnect of individual segments. The contacting between carrier substrate and OLED segment device is preferably done via electrical conductive adhesive, ultrasonic welding etc.
According to a further preferred embodiment of the invention, an additional layer of an electrically conducting material is provided as a bus bar. Thus, optionally a low ohmic bus bar is used for improved brightness uniformity among the various OLED segments. The bus bar is an additional layer of a high conducting material, such as aluminum, copper, silver etc. The intransparency of the bus bar structure can preferably be used as a decorative feature utilizing the high reflectance and mirror like appearance of small aluminum, copper or silver stripes. Moreover it can be used to hide the segment/carrier substrate contacting.
The segment devices and optional bus bar elements are preferably laminated onto the structured carrier substrate. An additional option is a bus bar patterned onto the target substrate. This can be done using standard techniques. For lamination, preferably a pressure/heat/uv activated adhesive is used. The resulting bi- layer device can be directly laminated onto the target substrate, e.g. a glass plate. Optionally, according to a preferred embodiment of the invention, another overlay foil can be used to encapsulate the OLED segments.

DETAILED DESCRIPTION OF EMBODIMENTS
From Fig. 1 a set of multiple OLED devices 1 and an interface 2 for electrically contacting the OLED devices 1 according to a preferred embodiment of the invention can be seen. According to this preferred embodiment of the invention, the OLED devices 1 are each encapsulated for themselves and then laminated onto the interface 2 which is a made of a structured carrier substrate 3 with a conductive ITO layer 4. An OLED device 1 with its segment stack is shown in more detail in Fig.
2. From top to bottom this OLED segment stack comprises 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, for example polyimide.
As can further be seen from Figs. 3 and 4, the set comprising the OLED devices 1 can be laminated on a glass plate 11 in different ways: While according to the embodiment shown in Fig. 3, the set is directly laminated onto the glass plate 11 and covered with a PVB foil 12, according to the embodiment shown in Fig. 4, for laminating the set onto the glass plate 11, an interlay er PVB foil 13 is used.
Further, from Fig. 5 a set with OLED devices 1 in glyph shape can be seen. According to this preferred embodiment of the invention, an anode 14 and a cathode 15 are provided with a gap 16 in between. The OLED devices 1 in glyph shape are placed across the gap 16 and electrically connected with the anode 14 and the cathode 15, respectively, with the aid of a contact point 17 contacting the anode 14 and a contact point 18 contacting the cathode 15.
As can be seen from Fig. 6, this embodiment can be modified such that low ohmic metal bars 19 as bus bars are provided for contacting the single OLED devices 1. These low ohmic bus bars 19 provide for improved brightness uniformity among the OLED devices 1. The bus bars 19 are made of an additional layer of a high conducting material, such as aluminum, copper or silver. The intransparency of the bus bars 19 is used as a decorative feature utilizing the high reflectance and mirror like appearance of the small metal stripes. Moreover, it is used to hide the segment/carrier substrate contacting, i.e. contact points 17, 18 which are now invisible. From Fig. 7, a cross sectional view of such an arrangement with laminated bus bars 19 can be seen.
Finally, from Fig. 8 a further modified embodiment of the invention can be seen according to which the anode 14 is structured. This means that anode 14 is comprised of multiple parallel stripes 20, wherein adjacent stripes 20 are separated and electrically insulated from each other by a gap 21, respectively. In order to individually connect the respective OLED devices 1 , connecting brackets 22 are used which are clipped onto the structured anode 14. This way, a customized set of OLED devices 1 can be achieved in an easy manner. While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive; the invention is not limited to the disclosed embodiments.
