The mobile communication system includes a folder part including a display module, a main part including a main module electrically grounding the display module, and a hinge module, installed to the folder part and pivotally coupled to the main part, for rotating the folder part towards or away from the main part and electrically grounding the display module via the main module. ## Claims ### Claim 1 A mobile communication system comprising: a folder part comprising a display module; a main part comprising a main module electrically grounding the display module; and a hinge module, installed to the folder part and pivotally coupled to the main part, for rotating the folder part towards or away from the main part and electrically grounding the display module via the main module. ### Claim 2 (depends on 1) The mobile communication system of claim 1, wherein the folder part further comprises: a folder housing comprising an inner empty space for receiving the display module; and a metal connector for connecting the display module and the hinge module in the inner empty space. ### Claim 3 (depends on 2) The mobile communication system of claim 2, wherein the folder part further comprises: a contact rib for contacting the metal connector to the hinge module, wherein the contacting rib protrudes from the folder housing to the inner empty space and contacts the metal connector. ### Claim 4 (depends on 3) The mobile communication system of claim 3, wherein the folder part further comprises: a contact member for providing an elastic force to the metal connector and for contacting the metal connector to the hinge module, wherein the contact member is placed in an empty space defined as the metal connector is bent and wherein the contact member respectively contacts the contact rib and the hinge module. ### Claim 5 (depends on 2) The mobile communication system of claim 2, wherein the folder part further comprises: a fix rib for fixing the display module in the inner empty space, wherein the fix rib protrudes from the folder housing to the inner empty space and wherein the fix rib contacts the display module. ### Claim 6 (depends on 2) The mobile communication system of claim 2, wherein the folder part further comprises: a connection gasket for electrically connecting the display module to the metal connector, wherein the connection gasket is placed between the display module and the metal connector and wherein the connection gasket connects the display module and the metal connector. ### Claim 7 A hinge apparatus installed to a mobile communication system that comprises a folder part comprising a display module and a main part comprising a main module electrically grounding the display module, the hinge apparatus comprising: a hinge module, installed to the folder part and pivotally coupled to the main part, for rotating the folder part towards or away from the main part; and a metal connector for electrically connecting the display module to the hinge module so that the hinge module is electrically grounded via the main module. ### Claim 8 (depends on 7) The hinge apparatus of claim 7, wherein the folder part further comprises: a folder housing comprising an inner empty space for receiving the display module and the metal connector. ### Claim 9 (depends on 8) The hinge apparatus of claim 8, wherein the folder part further comprises: a contact rib for contacting the metal connector to the hinge module, wherein the contacting rib protrudes from the folder housing to the inner empty space and contacts the metal connector. ### Claim 10 (depends on 9) The hinge apparatus of claim 9, wherein the folder part further comprises: a contact member for providing an elastic force to the metal connector and for contacting the metal connector to the hinge module, wherein the contact member is placed in an empty space defined as the metal connector is bent and wherein the contact member respectively contacts the contact rib and the hinge module. ### Claim 11 (depends on 8) The hinge apparatus of claim 8, wherein the folder part further comprises: a fix rib for fixing the display module in the inner empty space, wherein the fix rib protrudes from the folder housing to the inner empty space and wherein the fix rib contacts the display module. ### Claim 12 (depends on 8) The hinge apparatus of claim 8, wherein the folder part further comprises: a connection gasket for electrically connecting the display module to the metal connector, wherein the connection gasket is placed between the display module and the metal connector and wherein the connection gasket connects the display module and the metal connector. ### Claim 13 A mobile terminal, the mobile terminal comprising: a folder part configured to have a display module installed therein; a main part comprising a main module electrically connected to and electrically grounding the display module; and a hinge module operatively connected to the folder part and the main part, the hinge module configured for selectively rotating the folder part towards or away from the main part and for electrically grounding the display module via the main module. ### Claim 14 (depends on 13) The mobile terminal of claim 13, wherein the folder part further comprises: a folder housing comprising an inner empty space for receiving the display module; and a metal connector for connecting the display module and the hinge module. ### Claim 15 (depends on 14) The mobile terminal of claim 14, wherein the folder part further comprises: a contact rib for operatively connecting the metal connector to the hinge module, wherein the contacting rib protrudes from the folder housing to the inner empty space and contacts the metal connector. ### Claim 16 (depends on 14) The mobile terminal of claim 14, wherein the folder part further comprises: a contact member for providing an elastic force to the metal connector and for operatively connecting the metal connector to the hinge module, wherein the contact member is placed in an empty space defined as the metal connector is bent and wherein the contact member respectively contacts the contact rib and the hinge module. ### Claim 17 (depends on 14) The mobile terminal of claim 14, wherein the folder part further comprises: a fix rib for fixing the display module in the inner empty space, wherein the fix rib protrudes from the folder housing to the inner empty space and wherein the fix rib contacts the display module. ### Claim 18 (depends on 14) The mobile terminal of claim 14, wherein the folder part further comprises: a connection gasket for electrically connecting the display module to the metal connector, wherein the connection gasket is placed between the display module and the metal connector and wherein the connection gasket connects the display module and the metal connector.
