The present application relates to an OLED panel for a lighting device and a method of manufacturing the same. An OLED panel for a lighting device includes: a substrate; a auxiliary wiring pattern having a plurality of wiring lines disposed on the substrate; a first electrode disposed on the substrate where the auxiliary wiring pattern is disposed, and having a planarized upper surface; a passivation layer disposed on the first electrode and disposed at least in an area above the auxiliary wiring pattern; an OLED emission structure disposed on the first electrode; and a second electrode disposed on the OLED emission structure. In the OLED panel for a lighting device, luminance uniformity may be improved through a dual auxiliary wiring pattern, and the upper surface of the first electrode is planarized. Accordingly, the area of the passivation layer is reduced, and thus a light-emitting area may be increased.

Flexible OLED panel for lighting device and method of manufacturing same

An OLED panel for a lighting device is provided. The OLED panel for a lighting device may include a substrate; a first auxiliary wiring pattern disposed on the substrate; a first electrode disposed on a substrate on which the first auxiliary wiring pattern is disposed; a passivation layer disposed on the first electrode within an area where the first auxiliary wiring pattern is disposed; a second auxiliary wiring pattern disposed on the passivation layer to form a plurality of areas partitioned from each other; an OLED light emitting structure disposed in the plurality of areas partitioned by the second auxiliary wiring pattern; a second electrode disposed on the OLED light emitting structure and the second auxiliary wiring pattern; and, an encapsulating layer disposed on the second electrode. The OLED panel for a lighting device may form the respective OLED light emitting structures in an island shape, thereby improving luminance uniformity.

Disclosed herein is an OLED lighting apparatus which can achieve both improvement in reliability and reduction in manufacturing cost. In the OLED lighting apparatus, an encapsulation layer is disposed over the active area and the non-active area on a buffer layer, such that a pad disposed in the non-active area of the buffer layer can be stably secured by the encapsulation layer bonded thereto. Accordingly, upon tape automated bonding between an FPCB substrate with a COF tape attached thereto and a via electrode, the COF tape does not directly contact the pad but contacts the via electrode connected to the pad, particularly a connection terminal of the via electrode disposed on an upper surface of the encapsulation layer, thereby establishing electrical connection between the FPCB substrate and the via electrode. In this way, the connection terminal of the via electrode is electrically connected to the FPCB substrate via the COF tape, whereby a signal from the outside can be applied to the pad connected to the via electrode.
