Abstract
OLEDs are considered as the second solid-state-lighting technology for new flat, large-area, and efficient lighting solutions. OLED lighting on glass substrates has been successfully started the market entry.
The production of highly efficient OLED on larger area is still a challange. A Gen2 pilot line was installed at COMEDD. Latest results of this Gen2 manufacturing system for lighting and signage application, especially on transparent OLED and large area OLED will be presented.
A novel approach has been started to develop high efficient small molecule OLED stack deposition on flexible webs in a roll-to-roll vacuum process. Low cost metal foil as substrate for the OLED will allow a major cost reducing step, will open up new degrees of freedom in design leading and will be competitive for general signage and lighting applications. Metal foils as substrate for the deposition of organic light-emitting diodes in combination with the p-i-n OLED technology will allow a direct OLED deposition on metal foils. Within the COMEDD a roll-to-roll line based on vacuum deposition was succesfully installed. Monochrome devices process by roll-to-roll processes on 'endless' substrates will be presented.
