Researchers working in the European ROLLED project have developed a flexible OLED element that can be mass produced using roll-to-roll printing technology. The OLED elements can be used to add value to product packages. The new method is considerably cheaper than the traditional manufacturing method. The project was coordinated by VTT, and project participants included INM, CSEM, Ciba, Hansaprint, UPM and PolylC. At its simplest, the flexible OLED element can be used in product packaging, poste...
