The auxiliary or supporting electrodes are often utilized for the large‐emitting‐area OLEDs for better electrical properties. However, the auxiliary electrodes also blocked or absorbed the light from the emitter. In our optical simulation, we present the partitioned OLED units with the grid‐type auxiliary anode and patterned or center‐hollowed microlens‐array films to obtain more than 141.7% in relative luminance at normal direction.
