Organic lighting-emitting diode (OLED) is one of the most attractive technologies for next generation light source due to
its merits of good color rendering performance, diffuse area light source and high luminance efficiency. Despite its
strong potential as a large-area planner light source, light emitting area of one OLED lighting panel has been limited
because of high sheet resistance of transparent conductive electrodes and high risk of electrically short defects. In this
paper, we demonstrate a novel design for large-area OLED lighting panels with low electrode resistance and 100% short
reduction to achieve high brightness uniformity with low power efficiency loss and high production yield at the same
time. In addition, total light output of OLED lighting panels can be further enhanced by applying an internal extraction
layer between transparent electrodes and glass substrate.
