A method for generating an electrode layer pattern in an organic functional device (101; 201) comprising a first transparent electrode layer (103; 203), a second electrode layer (104; 204) and an organic functional layer (102; 202) sandwiched between said first and second electrode layers (103, 104; 203, 204).

摘要:
A method, for reducing occurrence of short-circuit failure in an organic functional device (101, 201, 401) comprising a first transparent electrode layer (104), a second electrode layer (105) and an organic functional layer (103) sandwiched between said first and second electrode layers (104; 105). The method comprises the steps of identifying (301) a portion of said organic functional device (101, 201, 401), said portion containing a defect (102a-g) leading to an increased risk of short-circuit failure, selecting (302) a segment (108a-g) of said second electrode layer (105), said segment corresponding to said portion, and electrically isolating (303) said segment (108a-g) from a remainder of said second electrode layer (105), thereby eliminating short-circuit failure resulting from said defect (102a-g).
摘要:
An OLED device includes a substrate, electrode layers and organic layers arranged on the substrate and at least one metal foil on top thereof. The first metal foil is electrically connected to one of the electrode layers. An enclosure of at least the organic layers is provided by the metal foil in conjunction with a sealant 113. Thus, the metal foil plays a major role in forming an OLED package. In addition, the metal foil provides a low ohmic external connection, which for example can be used for applying a driving current to the OLED.

摘要:
A device comprising a first transparent and electrically conductive layer (102), a second electrically conductive layer (104), and a functional layer (103) comprising at least one organic layer, sandwiched between said first and second conductive layers and to form a functional organic stack. At least one via (110) is arranged to electrically interconnect said first layer (102) and at least one segment (112) of said second layer (104), the segment being electrically insulated from the reminder of the second layer. The present invention makes it possible to uniformly supply the first transparent layer with electrical power. The vias and segments are preferably formed by laser applied through the transparent conductive layer.

摘要:
An organic light-emitting device is provided comprising a stack of layers including —an electro-optical layer structure (10) having a light emissive surface (12), —a light extraction structure (20) adjacent the light emissive surface, the light extraction structure has a nanostructured layer (22); and a backfill layer (24) comprising a material having a second index of refraction different from the first index of refraction, wherein the backfill layer (24) forms a planarizing layer over the nanostructured layer (22). The light emitting device includes a barrier film that comprises a first and a second inorganic layer (22, 26) and an organic layer (24) arranged between said inorganic layers. The one (22) of the inorganic layers of the barrier film closest to the electro-optical layer structure forms the nanostructured layer and the organic layer (24) between the inorganic layers forms the backfill layer.
