Mobile terminal and manufacturing method for heat spreader module

Abstract

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.

What is claimed is: 
     
         1 . An electronic device comprising:
 a display panel including a front surface and a rear surface;   a window configured to protect the front surface of the display panel;   a frame including a front surface of the frame to support the display panel and a rear surface of the frame;   wherein the front surface of the frame has a flat surface,   wherein the rear surface of the frame includes a battery mounting portion for providing a battery therein and a circuit board supporting portion for providing a circuit board therein,   wherein the battery mounting portion of the frame includes an opening,   a heat spreader disposed between the rear surface of the display panel and the front surface of the frame,   wherein the heat spreader includes an adhesion layer and a copper layer, and   wherein the adhesion layer is disposed between the display panel and the copper layer.   
     
     
         2 . An electronic device comprising:
 a display panel including a front surface and a rear surface;   a window configured to protect the front surface of the display panel;   a frame including a front surface of the frame to support the display panel and a rear surface of the frame;   wherein the front surface of the frame has a flat surface,   wherein the rear surface of the frame includes a battery mounting portion for providing a battery therein and a circuit board supporting portion for providing a circuit board therein, and   wherein the battery mounting portion of the frame includes an opening,   a heat spreader disposed between the rear surface of the display panel and the front surface of the frame,   wherein the heat spreader includes:   a heat spreading material layer composed of copper; and   a cover layer composed of polyimide and disposed between the heat spreading material layer and the frame,   wherein the heat spreading material layer includes at least one hole or at least one slit.
