  • Patent number: 10094965
    Abstract: A pattern displaying device includes a light path changing element, a first light source, a second light source, and a control module. The light path changing element has first inclined surfaces to reflect light and arranged into a first predetermined pattern, and second inclined surfaces to reflect light and arranged into a second predetermined pattern. The first light source is operable to emit light toward the first inclined surfaces to display the first predetermined pattern. The second light source is operable to emit light toward the second inclined surfaces in order to display the second predetermined pattern. The control module is electrically connected to the first and second light sources to control the first and second light source to emit light or not.

  • Publication number: 20130052294
    Abstract: A method of making a molding tool includes: preparing an imprinting master having a surface relief pattern; applying a curable material on a flexible film; embossing the curable material on the flexible film using the imprinting master so as to transfer the surface relief pattern to the curable material; curing the embossed curable material so as to form a patterned-and-cured material; attaching and conforming the flexible film to a non-planar surface of a model; forming a thin metal film over the patterned-and-cured material; electroforming a metal layer over the thin metal film so as to form a molding tool of the metal layer; and removing the molding tool from the thin metal film.
