German Companies Joined Forces in the Newly Founded German OLED Technology Alliance (GOTA).
April 03, 2017
​
The German partners aim to bundle their experience for the development and manufacturing of organic light-emitting diodes applications, each partner bringing its respective competencies at different stages of the value chain. Jointly, the partners hope to offer all-in-one solutions, with joint sales efforts to reach the Asian market, including China, Taiwan and Japan as its main markets. The GOTA consortium will target various fields of application such as OLED lighting, digital signage applications or displays for smartphones, tablets and TV sets.

• Von Ardenne brings experience in systems engineering and technology development for vacuum coating systems into the cooperation. The company masters all the steps of the structured PVD deposition of the relevant layers – from in-house developed deposition sources to entire coating systems. These layers are, for instance, layers from organic materials, for metallization, encapsulation layers or barrier layers. Beyond that, the Dresden-based company uses tempering furnaces for optimizing the layer systems. Its latest coating system FOSA LabX 330 Glass can be used for the manufacture of large-area OLEDs using a roll-to-roll process on flexible glass.
• Notion Systems develops and manufactures highly precise inkjet platforms for printing functional materials. The company has implemented many inkjet related industrial manufacturing processes and offers, among other things, entire process solutions for the circuit board and display industry. That includes the printing of active OLED and QLED layer systems in any desired display layout, the printing of passive color filters and thin-film encapsulation processes. Beyond that, the processes developed by Notion Systems can also be applied in other branches of the organic semiconductor industry and beyond, such as the lighting industry and organic photovoltaics.
• Fraunhofer IAP has been active in organic electronics research for 20 year and focuses on devices for applications such as OLED, OTFT, organic PV, perovskite solar cells, sensors and actuators. In a large clean room, the institute offers several processing technologies. These technologies range from spin coating to material evaluation with laboratory equipment to inkjet printing and slot-die coating on a robot controlled S2S pilot production line for substrate sizes of up to 150x150mm including several evaporation and encapsulation methods.
• MBraun is a provider of solutions for applications under protective gas atmosphere, including inert glove box workstations. With the help of these solutions, materials, products and processes that are affected by the influence of air can be developed and produced under certain defined conditions. The company has played an instrumental role in OLED research and manufacturing, providing laboratory equipment for vacuum and wet chemical coating, handling solutions for the substrate transport in pilot and production systems, surface cleaning processes and encapsulating technology. For the latter, Mbraun has developed special inert gas cluster solutions for thin-film encapsulation (TFE) of microdisplays on CMOS wafers, which have been successfully used for many years at production scale. The technical concepts are topped off by highly efficient cleaning systems, which enable almost particle-free production conditions even at industrial scale.
