Abstract
Official abstract text for this publication.
The invention relates to a method for manufacturing structured organic electroluminescent light-emitting devices (OLEDs) comprising light-emitting and non-emitting areas and to OLEDs manufactured according to this method comprising the steps of: Providing (P) a substrate ( 2 ) covered at least locally with at least one conductive layer as the first electrode ( 3 ); Depositing (D-SML) a stack modification layer ( 4 ) locally on top of the first electrode ( 3 ) to establish first areas ( 31 ) covered with the stack modification layer ( 4 ) and non-covered second areas ( 32 ) adjacent to the first areas ( 31 ) forming the desired structured pattern; —Depositing (D-OLS) the organic layer stack ( 5 ) comprising at least one organic light-emitting layer ( 51 ) on top of the first electrode ( 3 ) locally coated with the stack modification layer ( 4 ) providing an organic layer stack ( 5 ) being separated from the first electrode ( 3 ) by the stack modification layer ( 4 ) in between the organic layer stack ( 5 ) and the first electrode ( 3 ) in the first areas ( 31 ) and being in direct electrical contract to the first electrode ( 3 ) in the second areas ( 32 ); and Depositing (D-SE) a conductive metal layer as the second electrode ( 6 ) on top of the organic layer stack ( 5 ) to finish a functional layer stack ( 7 ), wherein the first areas ( 31 ) above the stack modification layer ( 4 ) remain free of the conductive metal without masking these first areas ( 31 ); —Providing an easy, variable and reliable method of a maskless structuring of the functional layer stack of OLED enabling to maintain the same the same deposition processes for the functional layer stack as applied during mask processing.
First claim
Opening claim text (preview).
The invention claimed is: 1. An organic electroluminescent light-emitting device with a structured pattern of non-emitting and light-emitting areas, the device comprising: a substrate coated at least locally with at least one conductive layer as a first electrode; a stack modification layer on top of the first electrode, the stack modification layer covering first areas and leaving non-covered second areas adjacent to the first areas thereby forming the structured pattern, the s…
