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: 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: An organic light emitting diode (OLED) lighting apparatus capable of improving lighting efficiency and lifetime by maximizing a light emitting area is disclosed. The OLED lighting apparatus may include a first electrode, which is provided with an embossing pattern at an interface at which the first electrode contacts an overcoat layer on a substrate. The first electrode may be made of a high refractive transparent conductive material, and may be arranged in an entire active area of the OLED lighting apparatus. The OLED lighting apparatus can improve light extraction efficiency through a light scattering due to a microlens effect through the first electrode provided with the embossing pattern, which facilitates elimination of a light extraction layer arranged at the interface between the substrate and the overcoat layer, thereby reducing a process yield and manufacturing cost.
