  • Patent number: 10804330
    Abstract: A multi-view display device displays a first image, a second image, and a third image generated using the arrangement structure of subpixels and color filters, the gaps between the subpixels, and the arrangement structure of black matrices. The first to third red subpixels of the first to third subpixel groups display a red portion of the first to third images, the first to third green subpixels of the first to third subpixel groups display a green portion of the first to third images, and the first to third blue subpixels of the first to third subpixel groups display a blue portion of the first to third images.

  • Patent number: 10692939
    Abstract: A multi-view display device, in which first to third red subpixels configured to display first-first to first-third view images are defined by dividing a red subpixel on which a first organic light emitting layer is deposited, first to third green subpixels configured to display second-first to second-third view images are defined by dividing a green subpixel on which a second organic light emitting layer is deposited, and first to third blue subpixels configured to display third-first to third-third view images are defined by dividing a blue subpixel on which a third organic light emitting layer is formed.

  • Publication number: 20030222379
    Abstract: The present invention relates to a method of manufacturing a metal clad laminate for printed circuit board, characterized by direct adhesion of a conductive metal foil without use of a thermosetting resin having low melting points, an adherent film or an adhesive. The method includes forming fine protrusions on at least one surface of a fluorine-based resin insulation layer, roughening one surface of a conductive metal foil, laminating the fluorine-based resin insulation layer having fine protrusions on the roughened metal foil so that the roughened surface of the metal foil and the protrusion-formed surface of the insulation layer face each other to form a laminated body, and compressing the laminated body under vacuum, pressure and heat.
