<p>A transparent electrode is provided for an organic light emitting diode (OLED) device. In certain embodiments, the electrode is made by sputter- depositing first and second transparent conductive oxide (TCO) layers of the same material (e.g., ITO), but with different stoichiometries, on a substrate. The first TCO layer is more oxided than is the second TCO layer. The TCO layers of the electrode on the substrate may then be heat treated (HT) at high temperature(s) in order to increase the work function (WF) and/or increase visible transmission of the electrode. The electrode is provided in an OLED device.</p> |
