Abstract: 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.

Abstract: A lighting apparatus using an organic light-emitting diode and a method of fabricating the same are characterized in that an organic emissive material and a conductive film used as a cathode are deposited on the entire surface of a substrate, and then an organic emissive layer in a lighting area and contact areas becomes separated (disconnected or cut) by laser ablation, simultaneously with the formation of a contact hole for contact with an anode. Next, cathode contact and encapsulation processes are performed using an adhesive containing conductive particles and a metal film. This simplifies the fabrication process of the lighting apparatus without using an open mask (metal mask), which is a complicated tool, thus making it useful especially in roll-to-roll manufacturing.

Abstract: According to a lighting apparatus of the present disclosure, an organic light emitting material and a metal layer may be deposited in a state that an edge region of a film being transported is blocked by a shielding member not to form an organic light emitting layer and a second electrode in a region on which a pad is formed. A lighting apparatus may be completed by separating the film as it is cut in a width direction, wherein the organic light emitting layer and the second electrode are exposed to the outside through the cut surface, and an open region from which the organic light emitting layer and the second electrode are removed in parallel to both cut surfaces may be formed within the lighting apparatus spaced apart from the cut surface of the film to disconnect the organic light emitting layer.

Abstract: According to the present disclosure, an organic light emitting material and a metal may be entirely deposited on a substrate without using an open mask to form an organic light emitting device, thereby facilitating application to a roll fabrication apparatus. A side surface of an organic light emitting layer may be exposed to the outside, but a step structure may be formed on an outer portion of the substrate, and the organic light emitting layer is disconnected between an outer region and a lighting region by the step of the step structure, thereby preventing moisture that penetrates into the organic light emitting layer in the outer region from being propagated to the organic light emitting layer in the lighting region.
