  • Patent number: 8497155
    Abstract: Certain example embodiments relate to organic light emitting diode (OLED)/polymer light emitting diode (PLED) devices, and/or methods of making the same. A first transparent conductive coating (TCC) layer is disposed, directly or indirectly, on a glass substrate. An outermost major surface of the TCC layer is planarized by exposing the outermost major surface thereof to an ion beam. Following said planarizing, the first TCC layer has an arithmetic mean value RMS roughness (Ra) of less than 1.5 nm. A hole transporting layer (HTL) and an electron transporting and emitting layer (ETL) are disposed, directly or indirectly, on the planarized outermost major surface of the first TCC layer. A second TCC layer is disposed, directly or indirectly, on the HTL and the ETL. One or both TCC layers may include ITO. The substrate and/or an optional optical out-coupling layer stack system may be planarized using an ion beam.

  • Patent number: 8445910
    Abstract: In an organic light emitting display, a conductive layer is formed on the bottom surface of a substrate, and the conductive layer is used as a wiring line for supplying a power source, and as the electrode of a capacitor. Therefore, it is possible to easily secure the aperture ratio of a pixel, to easily solve the problem of IR drops by controlling the area or thickness of the conductive layer, and to easily secure the electrostatic capacity of the capacitor. In particular, in the case of a front surface light emitting structure, since a capacitor of a metal/insulating layer/metal (MIM) structure may be formed in a light emitting region, enough aperture ratio and electrostatic capacity may be secured. Therefore, a high resolution organic light emitting display may be easily realized, and enough aperture ratio and electrostatic capacity are secured so as to realize high picture quality.
