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: 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 touch screen panel for a display device includes layers of polymer formed on both sides of a substrate for forming driving electrodes and sensing electrodes. The substrate may be made of materials such as polyethylene terephthalate (PET). Instead of bonding a window cover made of a heavy material, layers or polymer are formed on both sides of the substrate to afford rigidity to the touch screen panel. By removing the window cover, the weight and thickness of the touch screen panel can be reduced.
Abstract translation: 用于显示装置的触摸屏面板包括形成在用于形成驱动电极和感测电极的基板两侧的聚合物层。 衬底可以由诸如聚对苯二甲酸乙二醇酯（PET）的材料制成。 代替粘合由重材料制成的窗户盖，层或聚合物形成在基板的两侧，以提供触摸屏面板的刚性。 通过拆下窗户盖，可以减轻触摸屏面板的重量和厚度。

Abstract: A lighting apparatus using an organic light emitting diode and a method of fabricating the same according to the present disclosure is configured such that a contact electrode is formed using laser ablation and printing after an organic light emitting material, a conductive layer for a cathode and a passivation layer are deposited on an entire surface of a substrate, and then encapsulated with a metal film.The present disclosure simplifies a fabricating process of the lighting apparatus by virtue of a non-use of an open mask (metal mask) as a sophisticated apparatus, and particularly, can be effectively applied to a roll-producing process.Also, the present disclosure can provide an effect of improving reliability by preventing moisture permeation in a manner of covering an exposed contact portion with a protection film such as a barrier tape.

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.

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.
