Patent ID: 8502212

Claim:
An organic light emitting diode device comprising a sequence of serially electrically connected organic light emitting diode segments, the organic light emitting diode segment comprising two organic light emitting diodes, wherein the organic light emitting diodes are vertically stacked with their conducting directions pointing in opposed directions, wherein in the stack the organic light emitting diodes are electrically connected to each other by a common shared electrode, wherein the organic light emitting diode device comprising a sequence of serially electrically connected organic light emitting diode segments, wherein the sequence of segments comprises a given segment and a neighbouring segment, wherein the given segment comprises a first and second organic light emitting diode with a first common shared electrode and first and second unshared electrodes, wherein the neighbouring segment comprises a third and fourth organic light emitting diode with a second common shared electrode and third and fourth unshared electrodes, wherein the given segment is serially electrically connected to the neighbouring segment by an electrical connection of the first common shared electrode with the third unshared electrode and by an electrical connection of the second common shared electrode with the first unshared electrode, wherein any unshared electrode comprised in the sequence of segments is electrically connected to maximally one common shared electrode comprised in the sequence of segments.
