  • Publication number: 20180095317
    Abstract: A touch-panel liquid-crystal display device in one embodiment includes a metal line formed on a thin-film transistor array substrate, a gap column spacer and a push column spacer on a portion of a color filter array substrate that corresponds to an intersection of gate and data lines of the thin-film transistor array substrate, and a liquid-crystal layer between the thin-film transistor array substrate and the color filter array substrate. The gap column spacer and the push column spacer have the same height and the gap column spacer is located on the metal line, which facilitates an exposure process, minimizes generation of foreign substances when printing an alignment layer, and enables adjustment of the optimum amount of liquid crystals when liquid-crystal dotting is performed. The push column spacer is located on the metal line when the device can be pushed or bent by external force, and thus increases panel rigidity.

  • Patent number: 9746408
    Abstract: A dust sensor includes a multi-wavelength light source, a receiver, and a controller. The light source emits light of different wavelengths. The receiver generates one or more acoustic wave measurement values based on acoustic waves irradiated from the light source to air particles. The controller controls at least one flickering cycle of the light source, determines the type particles based on the acoustic wave measurement values, and calculates the concentration of particles. The controller calculates the concentration of particles in proportion to an intensity of the acoustic wave measurement values, and determine the type of particles based on the acoustic wave measurement values. The acoustic waves are generated differently based on wavelengths of light emitted from the multi-wavelength light source.

  • Publication number: 20170108489
    Abstract: The present invention relates to a novel function of lysyl tRNA synthetase, that is, lysyl tRNA synthetase interacts with 67LR through translocation of KRS into plasma membrane, and so enhances tumor (or cancer) cell migration, thereby having an effect on cancer metastasis. More specifically, it relates to method for controlling cancer metastasis or cancer cell migration by modulating an cellular level of lysyl tRNA synthetase, an use of an expression vector comprising a construct inhibiting KRS expression for preventing or treating cancer, an use of an agent inhibiting KRS activity for preventing or treating cancer, a method for screening an agent which modulates cancer metastasis or cancer cell migration, a method for screening an agent inhibiting an interaction between KRS and 67LR. Accordingly, cancer metastasis and cancer cell migration may be controlled using the inventive KRS, further the cellular metabolism related to laminin receptor (67LR) of plasma membrane may be controlled.
