The development of high performance organic light emitting diodes (OLEDs) for display and lighting applications has attracted considerable research interest from both academia and industry. In this work, the designs of simplified phosphorescent OLEDs with exceptionally high efficiency are discussed. It is found that discrete blocking layers and a double emission zone are unnecessary to achieve high efficiency in optimized phosphorescent OLEDs. Due to the elimination of these redundant layers, the device structure can be highly simplified. It is also shown that single-layer, two organic component devices are feasible with state-of-the-art efficiency.
