Patent number: 8022619Abstract: In order to improve the decoupling efficiency in a top-emitting OLED a top-emitting electroluminescent component (100) is suggested comprising a substrate, a first electrode (120) nearest to the substrate, a second electrode (14) located at a distance from the substrate, and at least one light-emitting organic layer (130) arranged between both electrodes, the emitted light being transmitted through the second electrode. The component in accordance with the invention is distinguished by an additional layer (150) facing away from the at least one organic layer is arranged on the side of the second electrode, which additional layer comprises optically effective light-emitting heterogeneities (151, 152, 153), especially in the form of scatter centers, the degree of transmission of the additional layer of the emitted light being greater than 0.6.Type: GrantFiled: July 12, 2005Date of Patent: September 20, 2011Assignee: Novaled AGInventors: Jan Birnstock, Martin Vehse, Tilmann Romainczk

Patent number: 7781961Abstract: In order, in the case of an OLED, to improve the coupling-out efficiency, a top emitting electroluminescent component (100) is proposed, comprising a substrate (110), a first electrode (120) closest to the substrate, a transparent electrode (140) located at a distance from the substrate, and at least one light-emitting organic layer (130) arranged between the two electrodes. The component according to the invention is distinguished by the fact that a coupling-out layer (150) is arranged on that side of the second electrode which is remote from the at least one organic layer, said coupling-out layer comprising conversion centres (151) which partly absorb the light emitted by the at least one organic layer and emit it again with an altered frequency.Type: GrantFiled: August 30, 2005Date of Patent: August 24, 2010Assignee: Novaled AGInventors: Jan Birnstock, Martin Vehse, Karl Leo

Publication number: 20080164807Abstract: 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.Type: ApplicationFiled: August 24, 2005Publication date: July 10, 2008Applicant: NOVALED GMBHInventors: Michael Hofmann, Jan Birnstock, Martin Vehse
