Within the LTM project, consortium partner Holst Centre / TNO has developed technologies for the roll-to-roll production of reliable ultra-thin, transparent OLED panels on an industrial scale. By focusing on printing the transparent electrode components using roll-to-roll manufacturing approaches Holst Centre/ TNO made some decisive steps towards the mass production of flexible OLEDs at low cost. OLED lighting and signage is at the moment a niche market in the high end sector, and one of the achievements of LTM is to contribute to making this technology more readily available and more affordable.

Furthermore, to make demonstrator production within the project possible, Holst Centre / TNO has worked on the technical realisation of flexible OLED devices in dedicated sizes and shapes matching the specific requirements for the various design demonstrators. This constitutes a milestone in the use of flexible OLEDs in design applications, since customised instead of standard sizes give designers much more freedom for creative product development.

In addition to cost and availability, another crucial issue for OLEDs being widely applied in customers products is device stability, i. e. lifetime. Here, Holst Centre / TNO has carried out an in-depth study of one particular suspect for shortening OLED lifetime, namely metal electromigration. Using a dedicated experimental setup, the process could be studied in detail and several strategies were tested to slow down this undesirable phenomenon. For more details about the flexible OLED see the PDF document.
