    • The invention provides an OLED device with improved light out-coupling, which can be manufactured easy and reliable at low costs, which comprises an electroluminescent layer stack (2, 3, 4) on top of a substrate (1), where the electroluminescent layer stack (2, 3, 4) comprises an organic light-emitting layer stack (3) with one or more organic layers sandwiched between a first electrode (2) facing towards the substrate (1) and a 10 second electrode (4), where the second electrode (4) comprises a layer stack of at least a transparent conductive protection layer (41) on top of the organic light-emitting layer stack (3), a transparent organic conductive buckling layer (42) on top of the protection layer (41) having a glass transition temperature lower than the lowest glass transition temperature of the organic layers within the organic light-emitting layer stack (3) and a stress inducing layer 15 (43) on top of the buckling layer (42) to introduce stress to the buckling layer (42). The invention further relates to a method to manufacture such OLED devices with heating the electroluminescent layer (2, 3, 4) stack to a temperature, which is above the glass transition temperature of the buckling layer (42) and below the lowest glass transition temperature of the organic layers within the organic light-emitting layer stack (3) for a time period sufficient 20 to obtain buckles (B) within the buckling layer (42).
    • 本发明提供了具有改进的光输出耦合的OLED器件,其可以以低成本制造得容易和可靠,其包括在衬底(1)的顶部上的电致发光层堆叠(2,3,4),其中电致发光层 叠层(2,3,4)包括有机层(3),其中一个或多个有机层夹在面向基板(1)的第一电极(2)和10第二电极(4)之间,其中 第二电极(4)包括在有机发光层堆叠(3)的顶部上的至少透明导电保护层(41)的层叠层,在保护层顶部的透明有机导电屈曲层(42) (41),其玻璃化转变温度低于有机发光层叠层(3)内的有机层的最低玻璃化转变温度和在屈曲层(42)的顶部的应力诱导层15(43),以引入 对屈曲层(42)的应力。 本发明还涉及通过将电致发光层(2,3,4)堆叠加热到高于屈曲层(42)的玻璃化转变温度并低于最低玻璃化转变温度的温度来制造这种OLED器件的方法 在有机发光层堆叠(3)内的有机层的时间间隔足够20以获得屈曲层(42)内的带扣(B)。
