Making a cathode structure for OLEDs |
摘要 |
A method of making a cathode structure for an OLED provided over organic layers includes evaporating a first layer over the organic layers, such layer including a metal or metal alloy whose work function is less that 4.0 eV, or a material including an electron-injecting dopant and a reactive metal; depositing at least one second layer of an inorganic material over the first layer to form a buffer structure with the first layer; and sputtering a protective layer of a metal or metal alloy provided over the buffer structure. |
