  • Publication number: 20240080383
    Abstract: Disclosed is a mobile terminal including: a first frame; a second frame slidable in the first direction with respect to the first frame; a flexible display unit that is bent to surround a portion of the mobile terminal, wherein the flexible display unit includes a front surface whose area size is variable based on the slide movement of the second frame and a rear surface; a slide frame slidable on a rear surface of the second frame in the first direction or a second direction, wherein an end of the rear surface of the display unit is coupled to a rear surface of the slide frame; and a stopper that restricts a movement range of the slide frame in the first direction. The mobile terminal provides a flat screen even in an extended state by minimizing a lift phenomenon of a variable portion of the display unit.

  • Patent number: 10497893
    Abstract: The present invention relates to graphene and, particularly, to a method for doping graphene using substrate surface modification, a method for manufacturing a graphene composite electrode using graphene and inorganic matter, and a graphene structure comprising the same. The method for doping graphene according to an embodiment of the present invention may comprise the steps of: forming, on a substrate, a precursor polymer layer for doping; and positioning graphene on the substrate on which the precursor polymer layer is formed. In addition, the method for manufacturing a graphene composite electrode according to an embodiment of the present invention may comprise the steps of: forming graphene on catalyst metal; forming a transparent conductive oxide on the graphene; crystallizing the transparent conductive oxide by applying heat of 150° C. or higher; and transferring, to a final substrate, a composite electrode consisting of the graphene and the transparent conductive oxide.
