Titel
Roll-to-roll deposition for organic light emitting diodes (OLED)
Abstract
OLED technology has successfully penetrated the display market within the last years. To enable OLED technology for further markets like signage and general lighting, cost reduction is a major issue. The use of ITO coated glass substrates as used for passive matrix displays is therefore not an option for lighting application. Low cost metal foil as substrate for the deposition of organic light-emitting diodes in combination with the p-i-n OLED technology will allow a major cost reducing step. Furthermore there is a need to replace sheet to sheet fabrication technologies by roll-to-roll-processing. Within the "Center of Organic Materials and Electronic Devices Dresden" (COMEDD) of Fraunhofer IPMS a roll-to-roll line for research and development in OLED lighting is currently going into process.
