    • A segmented electroluminescent device (100) with resistive interconnect layers (102), each segment (104,104', 104'') comprising an electroluminescent layer (110) arranged in between a first (106) and a second electrode (108) layer. The segments (104, 104', 104'') are connected via resistive interconnect layers (102), the resistive interconnect layers having a larger square resistance than the second electrode layer. The resistive interconnect layers (102) add a ballast resistance to the electroluminescent device such that no additional electric ballast is needed. As the electric ballast is divided over multiple layers the problem of a heat management for the electric ballast becomes less important. By adding an isolation layer (122) the surface of the resistive interconnect layers (102) can be increased to almost the whole surface of the electroluminescent device (100). The system of the electrode layer(108), the isolating layer (122) and the resistive layer (102) functions as a capacitor.
    • 具有电阻互连层(102)的分段电致发光器件(100),每个段(104,104',104“)包括布置在第一(106)和第二电极(108)层之间的电致发光层(110)。 所述段(104,104',104“)经由电阻互连层(102)连接,所述电阻互连层具有比所述第二电极层更大的方形电阻。 电阻互连层(102)增加了电致发光器件的镇流电阻,使得不需要额外的电动镇流器。 由于电动镇流器分多层,电气镇流器的热管理问题变得不那么重要。 通过添加隔离层(122),电阻互连层(102)的表面可以增加到电致发光器件(100)的几乎整个表面。 电极层(108),隔离层(122)和电阻层(102)的系统用作电容器。
