제목 Durability test using bending of large-area flexible OLED
초록 Recently, research on potential applications has been actively carried out because application of flexible organic light emitting diode (OLED) has become more important. In addition to improving efficiency, large-area and bending test studies are essential. Plastic based flexible OLED have been studied, but bending test has not been studied systemically. In this study, a plastic substrate was used to fabricate flexible OLED, and an inorganic layer as a barrier layer was formed on surface of the plastic substrate using atomic layer deposition (ALD). After OLED fabrication, a thin plastic film was used as encapsulation and the bending test was conducted systematically according to the bending radius (Rd). As a result, I-V-L analysis before and after the bending test confirmed the potential for durability.
