Zusammenfassung:A method of making an inverted bottom-emitting OLED device, comprising: providing a substrate; providing one or more first electrodes driven by n-type transistors on the substrate; providing an electron-transporting layer over the substrate and first electrode(s), wherein the electron-transporting layer comprises an n-type inorganic semiconductive material with a resistivity in the range of 1 to 105 ohm-cm and a bandgap greater than 2.5 eV; providing an organic light-emitting layer over the electron-transporting layer; providing a hole-transporting layer over the organic emitting layer; and providing a second electrode over the hole-transporting layer.
