  • Patent number: 10651418
    Abstract: An organic light emitting diode comprising a first electrode layer, a second electrode layer, a stack of functional layers, including an organic light-emitting layer, sandwiched between said first electrode layer and said second electrode layer, and an passivation layer arranged adjacent to said first electrode layer is disclosed. The passivation layer reacts with the first electrode layer to form an oxide at a reaction temperature that is induced by an evolving short circuit between the first electrode layer and the second electrode layer. The passivation layer is unreactive at temperatures lower than the reaction temperature.

  • Patent number: 10062858
    Abstract: The invention relates to method for manufacturing an electronic device comprising an organic layer (120). According to this method, a stack with a metal layer (130) and an organic layer (120) as first and second outer layers is structured by etching both these outer layers. In one particular embodiment, an additional metal layer (140) may be generated on the outermost metal layer (130) by galvanic growth through a structured isolation 10 layer (150). After removal of said isolation layer (150), the metal (130) may be etched in the openings of the additional metal layer (140). In a further etching step, the organic material (120) may be removed in said openings, too.

  • Publication number: 20160329387
    Abstract: The present invention relates to organic light emitting diodes (OLEDs) wherein organic photoresist layers are used as dielectric layers for electrical isolation. When organic photoresist layers are used as dielectric layers in OLEDs, a problem called “pixel shrinkage” may occur. According to the invention, the problem of pixel shrinkage can be solved by using an acrylic resin such as methyl methacrylate or a solution of polyimide in gamma-butyrolactone to form the dielectric layer. There is provided an organic light emitting diode (100) comprising: a substrate layer (110); a first electrode layer (120); a second electrode layer (130); an active layer (140) in-between the first and second electrode layers (120, 130); and a dielectric layer (150) configured to provide an electrical isolation between the first and second electrodes (120, 130). The dielectric layer (150) comprises a dielectric material configured to produce a reduced amount of or no by-products during a curing process.
