Luminance loss resulting from potential drop on the transparent indium tin oxide (ITO) electrode due to its relatively high resistivity is one of the most essential issues in the design of large-area organic light-emitting diode (OLED) lighting panels. One solution is to pattern metal grid with low sheet resistance on the ITO electrode. However, the shape, height, and width of the metal grid element have a great influence on the final luminance uniformity of the device. In this paper, a method is proposed to optimize these parameters in order to get the best luminance uniformity for large-area OLED lighting panels. The method takes two grid geometry parameters-height and width-into account and predicts the highest relative luminance by finite element method simulations under different operating voltages.
