High reliability, high efficiency, integratable organic light emitting devices and methods of producing same

摘要

An organic light emitting device (OLED) having an inverted structure including a cathode layer which is deposited on a substrate and on top of which an electron transporting layer (ETL), an electroluminescent (EL) layer, a hole transporting layer (HTL), a protection layer and an anode are deposited in sequence. The inverted OLED (IOLED) provides improved longevity, flexibility and efficiency over conventional OLEDs.
