Patent number: 9208707Abstract: A method for fabricating a display window member for a portable terminal includes: fabricating a surface sheet to be attached to a surface of the window member; introducing the surface sheet into a mold; and molding the body of the window member by pouring poly synthetic resin into the mold, and at the same time, attaching the surface sheet to the outer surface of the body. Since the window member fabrication method employs a dual injection molding using polymer synthetic resin, the fabrication method can easily reduce the weight of the window member compared to the conventional fabrication method using a glass material only and can reinforce the surface hardness of the window member while easily fabricating the window member.Type: GrantFiled: July 11, 2012Date of Patent: December 8, 2015Assignee: Samsung Electronics Co., Ltd.Inventors: Ho-Suk Rhyu, Jae-Chul Jin
