Patent ID: 8841654

Claim:
An organic light-emitting diode lighting apparatus, comprising: a transparent substrate main body with a plurality of groove lines formed therein, each of the plurality of groove lines having a depth of less than about 50% of the transparent substrate main body; a plurality of auxiliary electrodes formed in the plurality of groove lines, each of the plurality of auxiliary electrodes having a length less than or equal to a depth of each of the plurality of groove lines and each of the plurality of auxiliary electrodes having a thickness in a range of about 2 μm to about 100 μm; a plurality of positive temperature coefficients (PTCs) positioned directly on top of and in contact with the plurality of auxiliary electrodes, the plurality of PTCs positioned outside of the the plurality of groove lines; a first electrode being formed of a continuous single layer over the transparent substrate main body and the plurality of PTCs, the first electrode physically separated from the plurality of auxiliary electrodes, the first electrode physically contacting the plurality of PTCs, and the plurality of PTCs configured to electrically connect the plurality of auxiliary electrodes and the first electrode; an organic emission layer formed on and in contact with the first electrode; and a second electrode formed on the organic emission layer.
