a sensing unit installed in the display unit to sense a bending direction of the display unit; and a controller which changes a screen mode of an object displayed on the display unit according to the bending direction. ### Claim 2 (depends on 1) The display apparatus of claim 1, wherein if the display unit is concavely bent along with a screen, the controller moves an object, which has been displayed on the screen, toward a bending axis depending on the external pressure. ### Claim 3 (depends on 2) The display apparatus of claim 2, wherein the controller adjusts at least one of a display form and a size of the object displayed on the screen according to a distance from the bending axis in order to display a different perspective of an object which is moved toward the bending axis. ### Claim 4 (depends on 2) The display apparatus of claim 2, wherein if the display unit which has been concavely bent is convexly bent along with the screen, the controller moves an object, which is moved toward the bending axis, to an edge of the screen. ### Claim 5 (depends on 4) The display apparatus of claim 4, wherein the controller adjusts at least one of a display form and a size of the object displayed on the screen according to a changed distance from the bending axis according to an external pressure in order to display a different perspective of an object which is moved to the edge of the screen. ### Claim 6 (depends on 2) The display apparatus of claim 2, wherein the sensing unit senses a bending degree of the display unit, and wherein the controller changes a moving speed of the object, according to the bending degree of the display unit. ### Claim 7 (depends on 2) The display apparatus of claim 2, wherein the controller displays a Graphical User Interface (GUI) for selecting one of a plurality of objects displayed on the screen and moves and displays an object overlapping with the GUI to a center of the screen at a time when the display unit which has been concavely bent along with the screen returns to its original state. ### Claim 8 (depends on 1) The display apparatus of claim 1, wherein the sensing unit senses an incline direction of the display unit, wherein the controller moves and displays an object, which is positioned in the incline direction of the display unit on the screen, to the center of the screen. ### Claim 9 (depends on 1) The display apparatus of claim 1, wherein if the display unit is convexly bent along with the screen, the controller displays additional information related to an object which has been displayed on the screen. ### Claim 10 (depends on 9) The display apparatus of claim 9, wherein the additional information comprises at least one of a preview and detailed information of the object which has been displayed on the screen. ### Claim 11 A method of changing a screen mode of a display apparatus comprising a display unit which is bendable by external pressure, the method comprising: sensing a bending direction of the display unit; and changing a screen mode of an object displayed on the display unit according to the bending direction. ### Claim 12 (depends on 11) The method of claim 11, wherein changing the screen mode comprises, if the display unit is concavely bent along with a screen, moving an object, which has been displayed on the screen, toward a bending axis depending on the external pressure. ### Claim 13 (depends on 12) The method of claim 12, wherein changing the screen mode further comprises adjusting at least one of a display form and a size of an object displayed on the screen according to a distance from the bending axis in order to display a different perspective of an object which is moved toward the bending axis. ### Claim 14 (depends on 12) The method of claim 12, wherein changing the screen mode further comprises, if the display unit which has been concavely bent is convexly bent along with the screen, moving an object, which is moved toward the bending axis, to an edge of the screen. ### Claim 15 (depends on 14) The method of claim 14, wherein changing the screen mode further comprises, adjusting at least one of a display form and a size of an object displayed on the screen according to a changed distance from the bending axis according to an external pressure in order to display a different perspective of an object which is moved to the edge of the screen. ### Claim 16 (depends on 11) The method of claim 11, further comprising: sensing a bending degree of the display unit, wherein changing the screen mode comprises changing a moving speed of the object, according to the bending degree of the display unit. ### Claim 17 (depends on 12) The method of claim 12, wherein changing the screen mode further comprises: displaying a GUI for selecting one of a plurality of objects displayed on the screen; and moving and displaying an object overlapping with the GUI to a center of the screen at a time when the display unit which has been concavely bent along with the screen returns to its original state. ### Claim 18 (depends on 11) The method of claim 11, further comprising: sensing an incline direction of the display unit, wherein changing the screen mode comprises moving and displaying an object, which is positioned in the incline direction of the display unit on the screen, to the center of the screen. ### Claim 19 (depends on 11) The method of claim 11, wherein changing the screen mode comprises, if the display unit is convexly bent along with the screen, displaying additional information related to an object which has been displayed on the screen. ### Claim 20 (depends on 19) The method of claim 19, wherein the additional information includes at least one of a preview and detailed information of the object which has been displayed on the screen.
