  • Patent number: 9577400
    Abstract: Provided is a frequency shifting optical swept light source system. The system includes a light source that emits light; an amplifier that amplifies the light output from the light source; an optical converter that shifts a frequency of the amplified light and compresses a spectrum of the amplified light; and a controller that controls a current signal applied to the light source such that a repetition rate of the light output from the light source is adjusted, so that an intensity of the amplified light is adjusted, to thereby adjust a position of the compressed spectrum with respect to a predetermined frequency band.

  • Patent number: 9190421
    Abstract: A display device and a fabrication method thereof are provided. In a dual-link structure for a narrow bezel, first link wirings are formed on the same layer that the gate lines are formed and second link wirings are formed on the same layer that the data lines are formed. The first link wirings and the second link wirings are formed in a non-display area. Or auxiliary link wirings are further formed over the first link wirings and the second link wirings respectively. Or the first link wiring and second link wiring are divided two pieces of sub-link wirings. The sub-link wirings consisting the one link wiring are connected respectively and are formed on the different layer, whereby a defective image due to a difference in resistance between neighboring link wirings can be improved.
