  • Increasingly are a variety of electrical devices, such as mobile phones, with a display element based on organic light-emitting diodes (OLED display element) fitted. It is under an electrical device each Device understood, which has a power and / or power supply or with a connected or connectable, wherein the mode of action of equipment at least partially based on the utilization of the provided electricity based.
  • Around to integrate an OLED display element into an electrical device, it is known first the OLED display element on a substrate, for example a glass substrate, form and arranged on the substrate OLED display element to install in a subsequent step in the housing of the electrical device and connect to the power supply. This is an adaptation of the OLED display element to the shape of the electrical device, in particular then when the electrical device no flat surfaces has, problematic. Thus, when using non-planar housing surfaces often cavities, which the handiness of the device clearly can reduce.
  • Another disadvantage is that the production time of an electrical device with an OLED display element by the necessary mechanical and electrical connection of OLED display element and electrical device leads to a relatively high production time, which means a cost disadvantage. DE 19840772 C1 discloses a display device in the form of a liquid crystal display device in which connection wires can be inserted and positioned in a manner which is easy to handle by machine. However, the contacting takes place here later, ie after the display device.
  • Additionally disadvantageous affects the use of a flat glass substrate, on which the display is built into an electrical device before installation is, insofar from, as the substrate a significant proportion on the total weight of the display forms.
  • In WO 03/041080 A2 becomes a housing of the type mentioned above, for described a container on the surface of an OLED display element can be applied. A part of the housing can be used as a substrate for the OLED display element may be formed. From this document goes does not indicate how the OLED display element is applied to the housing becomes.

This means that the OLED display element directly on the case of the electrical device applied or manufactured, without previously on an extra provided for it Substrate to be applied. This will be advantageous the use of a substrate (usually a glass substrate) on which applied according to the prior art, the OLED display element first is saved. Thus, the housing surface provides the substrate for the OLED display element represents.
  • Surprisingly was found to be a direct application of an OLED display element on a housing surface, itself if this has a non-planar surface, by use the ink jet printing technique for applying the (polymeric) emitter molecules is possible.
  • It is according to the invention thereby provided the housing area, on which the OLED display element is to be arranged, in such a way to treat or structure, as for the production and function an OLED display element is advantageous. So is in a preferred variant a surface structuring for fixing an ink drop (polymer ink) on the case, the Application of barrier layers against oxygen and moisture and / or the application of metal layers for charge injection into the OLED structure etc. provided.
  • In a further, preferred embodiment is the driver electronics for the OLED display element inside the housing of the electrical device arranged, wherein the connecting line between driver electronics and OLED display element the casing penetrates. Preferably, the connection line between Driver electronics and OLED display element a plug on.
  • The inventive method for producing an electrical device with a housing and at least one OLED display element, wherein at least a part of the Electrode layers and the emitter layer of the OLED display element directly on the housing surface of the equipment be applied, is characterized in that in advance the contacts for contacting the electrode layers with the driver electronics of the OLED display element are introduced into the housing, wherein the contacts penetrate the housing and with the outside the housing is finally formed and subsequently the electrode layers directly onto the contacts be applied. As a result, advantageously, a subsequent connection avoided the OLED display element with the driver electronics, which the production time of the device according to the invention can be significantly reduced can.
  • At the inventive method becomes at least a part of the layers of the OLED display element, i.e. the anode layer, the cathode layer and the emitter layer, directly on the housing surface of the electrical device applied. In a particularly preferred embodiment, the electrode layers (Anode and cathode layer) and the emitter layer of the OLED display element Completely on the housing surface of the electrical device, applied without prior use of an additional substrate. This means that the housing surface as Substrate (carrier) for the OLED display element is used.

On the other side of the connecting line is a plug for connection provided with the driver electronics. By a direct application the anode or Kothodenschicht on the previously integrated into the housing connector or on the previously integrated connection line can be an afterthought soldering step be saved. For this purpose, preferably the anode layer is directly on the contact for contacting the anode layer (with the driver electronics) of the OLED display element applied by thermal evaporation. The cathode layer is preferably directly on the contact for contacting the cathode layer (with the driver electronics) of the OLED display element by thermal Vaporizing and / or RF sputtering applied. Furthermore, it is intended before applying the first layer of the OLED display element on the housing surface one Barrier layer, which preferably consists of silicon oxynitride, applied. This barrier layer is intended to be the OLED display element especially against oxygen and moisture, which is the lifetime of the OLED display element can reduce protect.
