Patent ID: 7576496

Claim:
A light emitting device, comprising: a substrate; and at least one organic light emitting diode (OLED) series group disposed on the substrate, said OLED series group comprising at least a first and a second OLED module, said OLED modules being electrically connected in series; wherein each OLED module further comprises a respective first electrode, second electrode, and light emitting layer, said first electrode being disposed on said substrate, and said light emitting layer being disposed such that a portion of said layer is between said first and second electrodes and configured to emit light upon application of a voltage between said respective first and second electrodes; at least one of said OLED modules further comprising an electrically-conductive interconnect segment disposed so as to be electrically coupled to the first electrode of said first OLED module; said interconnect segment further being disposed over a portion of said substrate disposed between said first OLED module and said second OLED module and further disposed to be electrically coupled to the second electrode of said second module.
