Patent ID: 8686632

Claim:
An organic electroluminescent device having a plurality of pixels, the device comprising: an anode formed on a substrate; an organic electroluminescent layer formed on the anode in each well of a well-defining layer to form the plurality of pixels; and, a cathode layer on the electroluminescent layer and a layer of metal on the top surface of the well-defining layer; wherein the device further includes a conductive layer deposited over the cathode layer and the metal layer to electrically connect the cathode layer of each of the plurality of pixels with the metal layer, wherein the plurality of pixels are arranged in a parallel arrangement, and wherein a ratio of a resistance of the conductive layer to a resistance of the organic electroluminescent layer at operating condition is in the range 1:10 to 1:100, such that the conductive layer provides a current limitation in the event of a short circuit of any one of the pixels.
