  • Publication number: 20100187552
    Abstract: 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 excitons formed in the OLED are used to obtain high-efficiency white light emission.

    Abstract: Provided is a transparent transistor including a substrate, source and drain electrodes formed on the substrate, each having a multi-layered structure of a lower transparent layer, a metal layer and an upper transparent layer, a channel formed between the source and drain electrodes, and a gate electrode aligned with the channel. Here, the lower transparent layer or the upper transparent layer is formed of a transparent semiconductor layer, which is the same as the channel. Thus, the use of the multi-layered transparent conductive layer can ensure transparency and conductivity, overcome a problem of contact resistance between the source and drain electrodes and a semiconductor, and improve processibility by patterning the multi-layered transparent conductive layer all at once, while deposition is performed layer by layer.
