The portable terminal includes a first display panel unit for displaying a first image, a second display panel unit for displaying a g the second display panel unit with the first display panel unit with supporting rotational shift, and a film connecting unit facing the hinge unit. A film is inserted in the connecting unit for connecting the first display panel unit with the second display panel unit electrically. ## Claims ### Claim 1 A portable terminal, comprising: a first display panel unit for displaying a first image; a second display panel unit for displaying a second image; a hinge unit for connecting the second display panel unit with the first display panel unit with supporting rotational shift; and a film connecting unit facing the hinge unit, wherein a film is inserted for connecting the first display panel unit with the second display panel unit electrically. ### Claim 2 (depends on 1) The portable terminal of claim 1, wherein the hinge unit comprises: a first hinge member mounted on the first display panel unit and having a cut piece and a connecting piece of which both sides are open; a second hinge member mounted on the second display panel unit and having one side which is open to communicate with one side of the first hinge member; and a hinge axis inserted into the first and the second hinge members. ### Claim 3 (depends on 2) The portable terminal of claim 2, wherein the hinge axis has a first hinge piece inserted into the first hinge member and a second hinge piece inserted into the second hinge member, and the diameter of the first hinge piece is greater than the diameter of the second hinge piece. ### Claim 4 (depends on 1) The portable terminal of claim 1, wherein the film connecting unit comprises: a first film connecting member having a connecting piece protruded from the first display panel unit, and a supporting piece caved in the first display panel unit; and a second film connecting member mounted on the second display panel unit and rotationally supported by the supporting piece of the first film connecting member. ### Claim 5 (depends on 4) The portable terminal of claim 4, wherein the connecting piece of the first film connecting member having upper portion protruded from the first display panel unit and lower portion guided into the inside of the first display panel unit, one side of the upper portion is closed, the other side of the upper portion is open, and the left and right sides of the lower portion are open. ### Claim 6 (depends on 4) The portable terminal of claim 4, wherein the second film connecting member has a cylindrical shape, one side of the second film connecting member is open to communicate with one side of the lower portion of the connecting piece, and a combining portion is formed to protrude in the circumferential direction in one side of the second film connecting member, and the combining portion is rotationally combined with the connecting piece of the first film connecting member. ### Claim 7 (depends on 4) The portable terminal of claim 4, wherein a film for connecting the first display panel unit with the second display panel unit electrically is provided to pass through the connecting piece of the first film connecting member and the second film connecting member. ### Claim 8 A method of interconnecting first and second display panel units in a portable terminal, the method comprising: connecting the first display panel unit to the second display panel unit so that the first display panel unit may rotate relative to the second display panel unit; providing a first film connecting member on the first display panel unit; providing a recessed portion on the first display panel unit adjacent the first film connecting member; providing a second film connecting member on the second display panel unit, the second film connecting member adapted to fit into the recessed portion of the first display panel unit and be positioned adjacent the first film connecting member to provide a channel between the first and second display panel units; and routing an electrical film through the channel to electrically interconnect the first and second display panel units. ### Claim 9 (depends on 8) The method of claim 8 wherein the operation of connecting comprises providing a hinge connected to the first and second display panel units. ### Claim 10 (depends on 8) The method of claim 8, wherein providing a first film connecting member comprises providing a cylindrical connecting member having openings on two opposing sides that forms a portion of the channel; and wherein providing a recessed portion comprises forming an arcuate supporting piece on the first display panel unit. ### Claim 11 (depends on 8) The method of claim 8 wherein providing a second film connecting member comprises providing a cylindrical member attached to the second display panel unit, the cylindrical member having an open side adapted to be positioned adjacent the cylindrical connecting member and having an inner surface, with a portion of the channel being formed between the open side and the inner surface. ### Claim 12 (depends on 8) The method of claim 8 wherein the electrical film comprises a tape carrier package or chip on film. ### Claim 13 (depends on 8) The method of claim 8 wherein the first and second display panel units are operable to function in combination to display a visual image. ### Claim 14 A portable terminal, comprising: a first display panel unit operable to display an image; a second display panel unit operable to display an image; a hinge member connected to the first and second display panel units and operable to allow the first display panel unit to rotate relative to the second display panel unit; and a film connecting member connected to the first and second display panel units, the film connecting member adapted to receive an electrical film for electrically connecting the first display panel unit to the second display panel unit. ### Claim 15 (depends on 14) The portable terminal of claim 14 wherein the portable terminal comprises a cellular phone. ### Claim 16 (depends on 14) The portable terminal of claim 14 wherein the film connecting member comprises: a first film connecting member having a connecting piece extending from the first display panel unit and a supporting piece recessed in the first display panel unit; and a second film connecting member on the second display panel unit, the second film connecting member being rotationally supported by the supporting piece of the first film connecting member. ### Claim 17 (depends on 16) The portable terminal of claim 16 wherein the first film connecting member has a cylindrical shape and comprises an upper portion extending from the first display panel unit and a lower portion recessed into the first display panel unit, the first film connecting member having one side of the upper portion which is closed and another side of the upper portion that is open, and the first film connecting member further having the left and right sides of the lower portion that are open. ### Claim 18 (depends on 17) The portable terminal of claim 17 wherein the second film connecting member has a cylindrical shape with one side of the second film connecting member being open to communicate with one side of the lower portion of the first film connecting member, and the second film connecting member including a combining portion extending circumferentially on one side of the second film connecting member, the combining portion being adapted to be rotationally connected to the first film connecting member. ### Claim 19 (depends on 18) The portable terminal of claim 18 wherein the film passes through the first and second film connecting members. ### Claim 20 (depends on 14) The portable terminal of claim 14 wherein the hinge member and film connecting member are positioned on opposite sides of the first display panel unit.
