HYBRID WHITE ORGANIC LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING THE SAME
摘要
<p>Provided are a hybrid white organic light emitting diode (OLED) and a method of fabricating the same. A HOMO level difference between a fluorescent emission layer and an electron transport layer in an organic emission layer (OLED) becomes higher than that between the other layers or a LUMO level difference between a fluorescent emission layer and a hole transport layer is higher than that between the other layers, so that a recombination region is restricted to a part of an emission layer to obtain high-efficiency fluorescent light emission. In addition, triplet excitons that are not used in a fluorescent emission layer are transferred to an auxiliary emission layer formed to be spaced apart from a recombination region by a predetermined distance to emit light in a different color from the fluorescent emission layer, so that both singlet and triplet exicitons formed in the OLED are used to obtain high-efficiency white light emission.</p>
