OLED lighting apparatus

Abstract:

Disclosed herein is an OLED lighting apparatus which can compensate for high sheet resistance of a first electrode formed of a transparent conductive material while improving light extraction efficiency through enhancement in aperture ratio. For this purpose, the OLED lighting apparatus omits auxiliary wires and, instead of the auxiliary wires, includes a first auxiliary wire and a second auxiliary wire to secure low resistance. As a result, the OLED lighting apparatus can compensate for high sheet resistance of the first electrode, thereby achieving normal light emission without reduction in luminance due to current drop when implemented as a large-area high-resolution lighting apparatus.
