  • Patent number: 9525151
    Abstract: Provided is an organic light emitting device including a nano composite layer. The organic light emitting device adopts a nano composite layer including an insulator and light emitting nano-particles within a device, thereby simultaneously insulating a control electrode and changing the color of light emitted from a light emitting layer, thereby improving external quantum efficiency. Further, the amount of electron holes and electrons injected into the light emitting layer may be adjusted through a voltage applied to the control electrode so as to secure a stable current when the device is operated. In addition, when compared to a conventional light emitting device, the surface area of positive and negative electrodes may be reduced so as to reduce reflectance with respect to external light.
