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: Disclosed herein is a drum for roll-to-roll deposition to rotate about a longitudinal axis. The drum is circular in a widthwise cross-section and has a shape in which opposite longitudinal edge portions each have a narrower width than a longitudinal central portion. By using the drum for roll-to-roll deposition according to embodiments of the present disclosure, it is possible to remove wrinkles occurring on a flexible substrate when a roll-to-roll deposition process is performed. As a result, it is possible to manufacture a film roll having a deposition layer with excellent widthwise thickness uniformity.

Abstract: 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.
