ELECTRON-TRANSPORTING LAYER FOR WHITE OLED DEVICE |
摘要 |
An OLED device including a cathode, an anode, one or more light-emitting layers disposed between the anode and cathode to produce white light and a layer disposed between the light-emitting layer(s) and the cathode. The layer includes a polycyclic aromatic hydrocarbon compound that has the lowest LUMO value of the compounds in the layer, in an amount greater than or equal to 10% by volume and less than 100% by volume of the layer; at least one second compound exhibiting a higher LUMO value than the polycyclic aromatic hydrocarbon compound, where at least one of the second compounds is a low voltage electron-transporting material, and the total amount of such second compounds(s) is less than or equal to 90% by volume of the layer; and a metallic material based on a metal having a work function less than 4.2 eV. |
