Abstract
According to principals as disclosed herein an organic, light emitting diode assembly is provided having a first electrode. An electron injection layer is adjacent to the first electrode. A first electron transport layer composed of inorganic material is adjacent to the electron injection layer. A second electron transport layer composed of organic material is adjacent to the first electron transport layer and in contact with an organic light emitting material layer. The organic light emitting material layer is in direct, abutting contact with the second electron transport layer. A hole transport layer is adjacent to the organic light emitting material layer and a second electrode is adjacent to the hole transport layer.
