Patent ID: 7358526

Claim:
An organic light emitting diode device, comprising: a substrate; a plurality of electrode contacts on the substrate; a first layer on the substrate, the first layer including finger portions, each finger portion being between two adjacent electrode contacts; a plurality of first electrodes on the substrate extending in a first direction; one or more organic layers on the plurality of first electrodes; a plurality of second electrodes on the one or more organic layers, wherein the plurality of second electrodes extend in a second direction different from the first direction and each have at least one end that overlaps with one of the electrode contacts; and a plurality of separating structures on the first layer and overlapping with the finger portions, wherein a profile of the separating structures is narrower at a portion proximal to the first layer than a portion distal to the first layer and the separating structures extend in the second direction and separate one second electrode from an adjacent second electrode; wherein the separating structures and the finger portions of the first layer extend beyond ends of the second electrodes.
