and a control unit for controlling a function of the device, wherein the control unit can control so that when a user's first input for an icon of the application displayed on the sub-region is received through the bended display, the icon is transformed into a preset form of an image and is displayed on the sub-region, and when a user's second input for the image is received through the bended display, a function corresponding to the second input among the functions of the application can be performed. ## Claims ### Claim 1 A bended display device, the device comprising: a bended display containing a main region located on a front side of the device and a sub-region extended from the main region and having a prescribed curvature; and a control unit configured to: control a function of the device; when a first touch input is received on an icon of an application displayed on the sub-region, transform the icon into a button image such that the button image is displayed instead of the icon on the sub-region, wherein the first touch input comprises dragging the icon in a first direction away from the main region, wherein the button image has a switch form, and wherein the button image has a size smaller than a size of the icon of the application; when a second touch input is received on the button image execute a function corresponding to the second touch input among a plurality of functions of the application; and when a third touch input is received on the button image, re-transform the button image into the icon of the application such that the icon is displayed instead of the button image on the sub-region, wherein the third touch input comprises dragging the button image in a second direction toward the main region. ### Claim 2 (depends on 1) The device of claim 1, wherein when a touch input of the user is received on the icon of the application displayed on the sub-region, the control unit is further configured to execute the application and cause the bended display to display a screen of the executed application on the main region. ### Claim 3 (depends on 1) The device of claim 1, wherein the button image is displayed at a position of the sub-region corresponding to a side of the device. ### Claim 4 (depends on 1) The device of claim 1, wherein the button image comprises an identifier identifying the application. ### Claim 5 (depends on 1) The device of claim 1, wherein the second touch input corresponds to at least one of a single touch input, a double touch input, or a long touch input for maintaining a touch for prescribed time. ### Claim 6 (depends on 1) The device of claim 1, wherein the control unit is further configured to cause the bended display to display an interface capable of configuring the function of the application corresponding to the second touch input on the main region. ### Claim 7 (depends on 1) The device of claim 1, wherein the control unit is further configured to cause the bended display to display a graphic effect on the button image to indicate that the application is in an active state when the function of the application corresponding to the button image is executed. ### Claim 8 (depends on 7) The device of claim 7, wherein the graphic effect corresponds to a graphic effect related to the function corresponding to the second touch input. ### Claim 9 (depends on 1) The device of claim 1, wherein the control unit is further configured not to display a screen of the application on the main region when the function corresponding to the second touch input is executed. ### Claim 10 A method of controlling a bended display device, which comprises a bended display containing a main region located on a front side of the device and a sub-region extended from the main region and having a prescribed curvature, the method comprising: when a first touch input is received on an icon of an application displayed on the sub-region, transforming the icon into a button image such that the button image is displayed instead of the icon on the sub-region, wherein the first touch input comprises dragging the icon in a first direction away from the main region, wherein the button image has a switch form, and wherein the button image has a size smaller than a size of the icon of the application; when a second touch input is received on the button image executing a function corresponding to the second touch input among a plurality of functions of the application; and when a third touch input is received on the button image, re-transforming the button image into the icon of the application such that the icon is displayed instead of the button image on the sub-region, wherein the third touch input comprises dragging the button image in a second direction toward the main region. ### Claim 11 (depends on 10) The method of claim 10, further comprising displaying a graphic effect on the button image to indicate that the application is in an active state when the function of the application corresponding to the button image is executed.
