Objective
Organic light emitting devices (OLED) are developing rapidly towards high performance displays. However, they also have huge potential for new low cost applications e.g. in packaging and printing industry. Even simple low resolution segment displays, displays with low pixel count or just fixed pattern light sources offer a wide area of new applications.
To reach the cost level required for this application field the production of the devices must be transferred to the low cost roll-to-roll processes, which can be integrated to the conventional printing and packaging processes used in industry. On the contrary to the typical semiconductor light sources, OLEDs have potential to be processed in continuous roll-to-roll processes. This requires selection and modification of suitable materials, effective patterning technologies, development of the manufacturing processes and improved encapsulation technologies. This development will be done keeping all the time the application, the potential and the required performance in mind.
The project's goal is the development of a cost-effective, volume-scale, roll-to-roll manufacturing technology for the realization of flexible OLED devices with arbitrary size and shape pixels and displays on web. These technologies are developed in order to achieve a well understanding of the production process structure. Technologies are tested and demonstrated in the manufacturing process of demonstrator displays.
