Transparent OLED device employing a mirror layer having a pattern of nontransparent and transparent zones

摘要

Disclosed is an OLED device including an organic layer disposed between an anode and a cathode, and a mirror layer on the anode or cathode. The organic layer is structured into electroluminescent zones and inactive zones, while the mirror layer is structured into nontransparent zones and transparent zones. Via an at least partial alignment of these structures, the OLED device can be made transparent for environmental light and simultaneously emissive in a dominant direction.
