  • Patent number: 10221307
    Abstract: A low gloss ASA-based resin composition having excellent weatherability and heat resistance is provided. The low gloss ASA-based resin composition is obtained by blending a general SAN copolymer, a heat-resistant SAN copolymer, a crosslinked aromatic vinyl compound-cyanide vinyl compound copolymer, and an amorphous inorganic material with large diameter and extra-large diameter ASA graft copolymers at a predetermined composition ratio. The low gloss ASA-based resin composition is useful in the manufacture of a high-quality molded article in which gloss characteristics are uniformly exhibited because impact resistance, heat resistance, flowability, weatherability, and low gloss characteristics are all excellent, and particularly, the gloss deviation on the entire surface of the injection molded article is significantly reduced.

  • Patent number: 10181293
    Abstract: A display apparatus includes: a backlight to generate light; a display panel to display an image by utilizing the light; a driving part to provide image signals corresponding to the image to the display panel; and a timing controller to drive the backlight, to drive the driving part at a first frequency when the image is a moving image, and to drive the driving part at a second frequency lower than the first frequency when the image is a still image. The timing controller is to set the second frequency based on a value obtained by applying a reduction rate of a flicker index corresponding to a dimming index of the backlight to a flicker index of image signals of a previous frame.

  • Patent number: 10023185
    Abstract: A fuel pump system of a hybrid vehicle is provided. The fuel pump system prevents a fuel pump from continuing to operate when fuel is exhausted, whereby the fuel pump may be damaged. The pressure of fuel is measured in response to exhaustion of fuel, and when the pressure of fuel is low, fuel is circulated within the fuel pump instead of being supplied to the engine side, thereby preventing the fuel pump from being stuck due to frictional heat.
