The development of the OLED type RTW-078 was aligned with the concept luminaire “Rollercoaster” which was equipped with 30 transparent RTW-078 panels. With a lighting area of 18 cm by 6.5 cm they are offering a transmission value of 57 %, which means they appear like a slight sunglass. In the on-state the transparent OLED emits light into two directions. As a unique benefit, a preferred emission direction can be fixed. This asymmetric emission ratio may be of advantage for some applications. The RTW-078 OLED panel generates light with a remarkable luminous efficacy value of 20 lm/W.
