  • Publication number: 20200306150
    Abstract: A solid temporal colorimetric hydrogel cosmetic composition includes 15 to 99.90 wt % of the water phase part and 0.10 to 85 wt % of the oil phase part, having a refractive index difference of 0 to 0.02 therebetween, and having a color change according to variations in a refractive index difference between the water phase part and the oil phase difference when applied to the skin. The cosmetic composition not only has flexibility through irradiation of gamma-rays, but also enables an optimal application time of the cosmetic composition to be visually confirmed through a color change from transparency to ivory white due to a change in the refractive index difference caused by absorbency and volatilization of water when applying the composition to the skin. The cosmetic composition is capable of improving quality of a product although a preservative irritating to the skin is not added.

  • Patent number: 10763323
    Abstract: An organic light-emitting diode display may have rounded corners. A negative power supply path may be used to distribute a negative voltage to a cathode layer, while a positive power supply path may be used to distribute a positive power supply voltage to each pixel in the display. The positive power supply path may have a cutout that is occupied by the negative power supply path to decrease resistance of the negative power supply path in a rounded corner of the display. To mitigate reflections caused by the positive power supply path being formed over tightly spaced data lines, the positive power supply path may be omitted in a rounded corner of the display, a shielding layer may be formed over the positive power supply path in the rounded corner, or non-linear gate lines may be formed over the positive power supply path.

  • Publication number: 20200274195
    Abstract: In order to improve the safety of a rechargeable battery, methods for manufacturing the rechargeable battery using a solid-state electrolyte are being studied. However, a process of manufacturing the all-solid state rechargeable battery by separately preparing and laminating an electrode and a solid-state electrolyte is not only complicated, but also may cause side reactions due to residual moisture between the electrode and the solid-state electrolyte. In addition, additional processes are required to reduce the interface resistance between the electrode and the solid-state electrolyte. In order to solve these disadvantages, the present invention is to manufacture an integral all-solid state rechargeable battery by applying a mixed slurry of a conductive ceramic material and a polymer mixed with a solvent onto an electrode, evaporating the solvent, absorbing a liquid electrolyte, and then covering the electrode with a counter electrode.
