  • Patent number: 11833800
    Abstract: A method for forming a three-dimensional curved surface on a laminated substrate is provided. In the method, the laminated substrate is brought into close contact with an elastic sheet. Here, the laminated substrate comprises a support substrate and a conductive layer on the support substrate, and the support substrate comprises a resin substrate comprising a thermoplastic resin. The elastic sheet is deformed while the laminated substrate is in close contact with the elastic sheet. The laminated substrate is brought into close contact with a temperature-controlled mold to soften the resin substrate.

  • Patent number: 10281793
    Abstract: An electrochromic dimming device is provided. The electrochromic dimming device includes an electrochromic element, a color development power source, a color discharge powder source, and a variable resistance. The color development power source supplies electric power to the electrochromic element when the electrochromic element develops color.
