  • 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.

  • Patent number: 9317149
    Abstract: Disclosed are a method for detecting a touch position of a touch screen and the touch screen using the same. A method for detecting a touch position on a touch screen includes the steps of: detecting a touched touch screen block among touch screen blocks by using signals generated from at least one touch sensor among touch sensors included in a plurality of touch screen blocks into which an area of the touch screen is divided; and detecting a touch position in the detected touch screen block on the basis of a signal of a touch sensor included in the detected touch screen block. Thus, compared to an existing method of processing a signal by reading measurement values of all measurement sensors, the invention enables fast signal processing, thereby reducing measurement signal processing time for measuring a touch position of a touch screen.
