  • Patent number: 8871563
    Abstract: A method of manufacturing an organic-light-emitting-diode (OLED) flat-panel light-source apparatus. The method includes 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.

  • Patent number: 8421064
    Abstract: Provided are an organic-light-emitting-diode (OLED) flat-panel light-source apparatus and a method of manufacturing the same. The device includes an anode and a cathode, to which externally applied power is supplied, disposed on a substrate, an organic emission layer (EML) interposed between the anode and the cathode and configured to emit light due to power supplied through the anode and the cathode, and a subsidiary electrode layer including a plurality of subsidiary electrodes bonded to the anode or the cathode and configured to supply power to the anode or the cathode or electrically insulated from the anode or the cathode and configured to supply power to other emission regions.

  • Patent number: 8408960
    Abstract: A method of fabricating an organic light emitting diode using phase separation. The method includes preparing a transparent substrate. A first light path control layer is formed on the transparent substrate. The first light path control layer includes a mixture of a first medium and a second medium having a lower refractive index than the first medium using the phase separation. An anode, an organic emission layer, and a cathode are sequentially stacked on the first light path control layer. In this method, an OLED with improved light extraction efficiency can be fabricated using a simple and inexpensive process.
