Abstract
An OLED device comprising an array of bottom-emitting OLED segments, each separated by a non-emitting gap, arranged on a common transparent substrate; wherein each OLED segment is defined by a transparent bottom electrode segment together with a top electrode and organic layers for light emission between the top electrode and bottom electrode segments; where each segmented bottom electrode is electrically connected to an individual power feed, wherein at least some of the power feeds are arranged between the bottom electrode segments and the transparent substrate within the emission light path; and includes at least one refraction-reducing material located between the segmented bottom electrode and the transparent substrate. The refraction-reducing material is located between the bottom side of the power feed and the upper side of the transparent substrate; and/or between the bottom side of the bottom electrode segments and the upper side of the power feed; and/or between the lateral spaces separating the individual power feeds.
