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: A lighting apparatus of the present disclosure may transport a film formed with a plurality of lighting apparatuses between rolls, and place a mask on an entire surface of the film to deposit an organic light emitting material in a state in which a part of the film is blocked to form an organic light emitting layer, and then deposit a metal layer by the same mask to form a second electrode, wherein the organic light emitting layer and the second electrode are not formed in a region where a pad is formed by the mask to open the pad and connect an external signal source thereto. The first electrode may be connected to a first pad and the second electrode may be connected to a second pad to apply a voltage, wherein a part of the organic light emitting layer is laser-etched to form a contact portion, and the second electrode is electrically connected to the second pad.

Abstract: An OLED lighting apparatus of a tiling structure in a seamless structure without a bezel area is discussed. The OLED lighting apparatus includes a first flexible OLED panel and a second flexible OLED panel. The first flexible OLED panel which a bezel area and one side of a light emitting area are bent, and the second flexible OLED panel which a bezel area is bent, are fastened by a fastening member, and a light guide plate and an optical member are arranged on the fastening member. As a result, the OLED lighting apparatus tiles by using the fastening member at a boundary portion to which the first and second flexible OLED panels contact, and the light guide plate and the optical member are applied on the fastening member, so that a light can be emitted even at the boundary portion to which first and second flexible OLED panels contact.
