    • The present invention relates to a light emitting device comprising several groups of stripe shaped organic light emitting diodes (15, 16, 17) arranged side by side on an optically transparent carrier substrate (4). The organic light emitting diodes (15, 16, 17) comprise a first layer sequence (2) forming a first microcavity. At least one of the organic light emitting diodes (15, 16, 17) of each group comprises a second layer sequence (3) forming a second microcavity between the second electrode layer (5) and the carrier substrate (4). The second microcavity is adapted in thickness of at least one of its layers to increase light out put of the corresponding organic light emitting diode (15, 16, 17). A scatter or diffuser element (14) is arranged in an emission direction of the organic light emitting diodes (15, 16, 17) in front of the carrier substrate (4), to mix the light of said different colors of each group leaving the carrier substrate. The present device allows the emission of white light with a high efficacy.
    • 本发明涉及一种发光器件,其包括并排设置在光学透明载体衬底(4)上的几组条形有机发光二极管(15,16,17)。 有机发光二极管(15,16,17)包括形成第一微腔的第一层序列(2)。 每组的有机发光二极管(15,16,17)中的至少一个包括在第二电极层(5)和载体衬底(4)之间形成第二微腔的第二层序列(3)。 第二微腔适于其至少一层的厚度以增加对应的有机发光二极管(15,16,17)的光输出。 在载体基板(4)的前面的有机发光二极管(15,16,17)的发射方向上布置散射体或散射体元件(14),将各组的不同颜色的光混合,离开 载体衬底。 本装置允许以高效率发射白光。
