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: 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.
