MOBILE TERMINAL AND MANUFACTURING METHOD FOR HEAT SPREADER MODULE

摘要

There is disclosed a mobile terminal including a display panel, a frame comprising a front surface where the display panel is disposed, a rear case coupled to one surface of the frame, to form an electric/electronic control unit there between the frame and the rear case, a heat spreader module provided between the display panel and the frame, wherein the heat spreader module includes a metallic plate in contact with the display panel, a heat spreading material layer disposed on a rear surface of the metallic plate and an adhesive layer disposed between the heat spreading material layer and the metallic plate to bond the metallic plate and the heat spreading material layer with each other. Even when the frame is partially eliminated, the mobile terminal may support the display panel and securing the heat spreading performance simultaneously, using the heat spreader module having a preset rigidity.
