Abstract: An organic light emitting diode (OLED) display device is described that includes a shared cathode between OLED pixels as well as auxiliary lines that are formed between rows and/or columns of the OLED pixels. As the cathode is shared between many if not all of the pixels of display device, resistance within the cathode can affect the brightness of those pixels that are further from the cathode's voltage source. The auxiliary lines serve to counteract the voltage drop caused by this resistance. The auxiliary lines are electrically connected to the cathode in close proximity to individual pixels of the display.
