In order to improve the fill factor as well as the efficiency for a structural element on the basis of an organic light-emitting diode facility, a display is proposed comprising a substrate, a first electrode (130) nearest to the substrate, a second electrode (160) away from the substrate and at least one light-emitting organic layer (150) arranged between both electrodes. The light emitted in the active zone transmits through one of the two electrodes whereby the first electrode is pixel-structured and an isolation layer (150) is arranged between neighbouring pixels. The display according to the invention is characterized in that the isolation layer (150) is optically coupled with the light-emitting layer (150), and has optically effective light-scattering and fill factor increasing heterogeneities (180, 190), whereby the isolation layer is micro-structured to match the pixel structure of the first electrode and is processed onto this. In addition, the invention concerns also a method for the manufacture of such a display.
Structural element on the basis of an organic light-emitting diode facility, particularly an OLED active matrix display, comprising a substrate, a first electrode nearest to the substrate, a second electrode away from the substrate and at least one light-emitting organic layer arranged between both electrodes whereby emitted light transmits through at least one of the two electrodes, and the first electrode is structured in pixels whereby an isolation layer is arranged section-wise between neighboring pixels, characterized in that the isolation layer is coupled optically with the light-emitting layer and has optically effective light-scattering and fill factor increasing heterogeneities where the isolation layer is micro-structured to match the pixel structure of the first electrode and is processed thereon.
