Patent ID: 8871563

Claim:
A method of manufacturing an organic-light-emitting-diode (OLED) flat-panel light-source apparatus, the method comprising: depositing a metal layer on a substrate and patterning the metal layer to form a plurality of subsidiary electrodes; forming an insulating layer on the substrate including the plurality of subsidiary electrodes and forming a first subsidiary electrode layer by etching the insulating layer until some of the plurality of subsidiary electrodes are exposed; and sequentially forming an anode, an organic emission layer (EML), and a cathode on the substrate on which the first subsidiary electrode layer is formed; wherein some of the plurality of subsidiary electrodes are bonded to the anode and supply power to the anode in an emission region less affected by IR-drop, and others of the plurality of subsidiary electrodes are electrically insulated from the anode and supply power to other emission regions in an emission region more affected by the IR-drop.
