68‐4: Top‐emission OLED Kawara‐type Multidisplay with Auxiliary Electrode

Abstract

We have developed a top-emission organic light-emitting diode (OLED) Kawara-type multidisplay with a novel auxiliary electrode. With this device, while the contact portion of the auxiliary electrode is developed in the display region, a high aperture ratio can be achieved. This technique can be utilized in any top-emission OLED display.

23‐3: Self‐Assembled Cathode Patterning for Micro‐Welding in Top‐Emission AMOLED Displays to Reduce IR Drop

“…The third approach is to create an area that cannot be covered by the organic layers due to an "undercut" structure and then to sputter Transparent Conductive Oxides (TCOs) such as Indium Tin Oxide (ITO) and Indium Zinc Oxide (IZO) on top of the cathode to make the connection between the auxiliary electrode and cathode over the exposed area. [5] The biggest problems for this approach are damages caused by the sputtering process, optical impacts of the TCO layer, and slow takt time.…”
