  • Publication number: 20190181193
    Abstract: An organic light-emitting display apparatus for selectively realizing circular polarization according to external light conditions, including a substrate; an organic light-emitting device on the substrate; a sealing member on the organic light-emitting device; a phase retardation layer on a surface of the substrate, the organic light-emitting device, or the sealing member; and a linear polarization layer on another surface of the substrate, the organic light-emitting device, or the sealing member, wherein the linear polarization layer is located to be closer to a source of external light than the phase retardation layer, and wherein the linear polarization layer comprises a photochromic material.

  • Patent number: 9608713
    Abstract: The present disclosure relates to an interference cancellation method and device of an ICS repeater using a leveler, and may effectively cancel only interference signals by using a leveler without using a magnetic correlation cancellation device or digital filter in order to cancel unnecessary noise signals generated by narrow-band signals and enable an ICS repeater design for an LTE wireless network that needs a short system time delay.

  • Patent number: 8608813
    Abstract: Disclosed are eco-friendly and low-price solid fuel, which is naturally dried, and a method of manufacturing the same. Disposable diapers or disposable sanitary pads, which are failed during the manufacturing process, are used to produce industrial alternative fuel having a low price through a predetermined process, so solid fuel having no pollution problem in combustion is provided. The solid fuel is mainly made of synthetic resin-pulp scrap including synthetic resin integrated with pulp like the disposable diapers or the disposable sanitary pads. The method includes introducing a scrap, such as the wasted disposable diaper or the wasted disposable sanitary pad, including synthetic resin integrated with pulp into a crusher to break the scrap into fragments, adding a slight amount of waste cooking oil serving as a binding agent to the fragments, performing an extrusion-molding with respect to the fragments, cutting the extrusion-molded fragments to make pallets, and then drying pallets.
