5 is a flowchart illustrating a method of controlling the operation of the portable terminal according to the first embodiment of the present invention.

5, in the portable terminal in which only the touch screen of the first display unit is exposed, the flexible display unit folded or rolled in the portable terminal is extended (S500). A menu icon or an execution screen of a menu may be displayed on the first display unit.

Next, the control unit 180 displays the contents on the flexible display unit and displays the pointer (S505). Here, the content may be a web page transmitted from a web server, or may be a digital multimedia broadcasting (DMB) broadcast. The content includes a moving image, an image, and text that can be displayed on the flexible display unit. Here, the pointer POINTER is an indicator that can indicate a specific area of the content displayed on the flexible display unit. It can be displayed in the form of arrows or fingers in general. In the display area of the flexible display unit, not only contents and pointers but also execution icons for performing specific operations on the contents can be displayed. For example, a storage icon for storing content, a scroll icon for scrolling the screen on which content is displayed, a playback icon for playing music or moving images, and the like may be displayed on the flexible display unit. Since the flexible display unit can also be implemented as a touch screen, the touch signal can be input to the execution icon through the flexible display unit.

When contents and pointers are displayed on the flexible display unit, the controller 180 may not display anything on the first display unit so that the first display unit may function as the touch pad of the mouse. Alternatively, the menu icon displayed on the first display unit or the execution screen of the menu may be deactivated and used as a simple keypad in step S500. That is, even if a touch signal for selecting the menu icon displayed on the first display unit is input through the touch screen of the first display unit, the menu icon is not executed and the input touch signal operates as a signal for the content displayed on the flexible display unit .

Next, the control unit 180 determines whether a directional touch signal is input through the touch screen of the first display unit (S510). Hereinafter, a directional touch signal will be described as an embodiment using a drag signal. If it is determined in operation S510 that the drag signal has been input, the controller 180 moves the pointer corresponding to the input drag signal and displays the pointer on the flexible display unit (S515). The pointer moves according to the trajectory of the drag signal, that is, according to the direction and movement distance of the drag signal. In general, since the touch screen of the first display unit is smaller than the display area of the flexible display unit, not only the pointer moves in the same direction and movement distance as the input drag signal, but also the display area of the flexible display unit of the first display unit The pointer can be moved and displayed in the direction in which the trajectory of the input drag signal is magnified and the movement distance in proportion to the relative size. On the other hand, as a result of the determination in S510, if the drag signal is not input, the position at which the pointer is displayed is not changed.

Next, the control unit 180 determines whether a plurality of touch signals are input at the same position of the touch screen through the touch screen of the first display unit (S520). Here, the same position of the touch screen refers to a range where the same position can be judged even if it is not necessarily the same physically. The range that can be judged as the same position can be set by the user. If it is determined in step S520 that a plurality of touch signals have been input, the menu corresponding to the position of the pointer displayed on the flexible display unit is executed, and the execution screen of the menu is displayed (S525). That is, a plurality of touch signals can serve as a signal for selecting a menu. For example, when a pointer is displayed on a specific product image among a plurality of product images, a plurality of touch signals are input, so that detailed information on a specific product image can be displayed on the flexible display unit. Since the execution screen of the menu is also a kind of content, the execution screen of the menu and the pointer are displayed on the flexible display unit. On the other hand, if it is determined in step S520 that the plurality of touch signals are not input, the contents and the pointer displayed on the flexible display unit are not changed.

Next, the control unit 180 determines whether there is a signal input through the touch screen of the first display unit for a predetermined time (S530). The predetermined time can be set by the user. If it is determined in step S530 that there is a signal input through the touch screen of the first display unit for a predetermined time, the content or the pointer is changed according to the input signal (S550), and the content and pointer are displayed on the flexible display unit ). For example, when the input signal is a drag signal, the pointer can be moved and displayed. When the input signal is a plurality of touch signals, a menu can be executed and displayed. If the input signal is a non-directional touch signal, the screen may not be changed.

If it is determined in operation S530 that there is no signal input through the touch screen of the first display unit for a predetermined time, the controller 180 ends the display of the pointer on the flexible display unit S535. That is, when there is no signal input through the touch screen of the first display unit for a predetermined time, the pointer disappears in the flexible display unit.

After the display of the pointer is completed, the control unit 180 determines whether a signal is input through the touch screen of the first display unit (S540). As a result of the determination in step S540, if a signal is input, the pointer is displayed again (S545), and the content or the pointer is changed according to the input signal (S550), and the content and the pointer are displayed on the flexible display unit (S505).

FIG. 6 is a flowchart illustrating a method of controlling a mobile terminal operation according to a second embodiment of the present invention.

As shown in FIG. 6, the flexible display part folded or rolled in the portable terminal is extended and unfolded (S600). Next, the control unit 180 displays the content on the flexible display unit and displays a pointer (S605). Here, the content may be a web page transmitted from a web server, or may be a DMB broadcast. Execution icons for performing a specific operation on the content may also be displayed in the display area of the flexible display unit.

Next, the controller 180 divides the touch screen of the first display area into three areas (S610). The three areas can be changed according to the user's setting. For example, the touch screen of the first display area can be divided into three areas evenly, and the area of each area can be divided into three areas. The roles of the first region, the second region, and the third region are changed.

Next, the control unit 180 determines whether a directional touch signal is input through the first area of the touch screen of the first display unit (S615). Hereinafter, a directional touch signal will be described as an embodiment using a drag signal. If it is determined in operation S615 that the drag signal has been input, the controller 180 moves the pointer corresponding to the trajectory of the input drag signal and displays the pointer on the flexible display unit (S620). On the other hand, if it is determined in step S615 that no drag signal is input, the position at which the pointer is displayed is not changed.

Next, the control unit 180 determines whether a touch signal is input through the second area of the touch screen of the first display unit (S625). If it is determined in operation S625 that the touch signal is input through the second area, a menu corresponding to the position of the pointer displayed on the flexible display unit is executed and an execution screen of the menu is displayed (S630). For example, it can act as the left button of the mouse. Since the execution screen of the menu is also a kind of content, the execution screen of the menu and the pointer are displayed on the flexible display unit. On the other hand, if it is determined in operation S625 that no touch signal is input through the second area, the content and pointer displayed on the flexible display unit are not changed.

Next, the control unit 180 determines whether a touch signal is input through the third area of the touch screen of the first display unit (S635). If it is determined in operation S635 that the touch signal is input through the third area, an information menu corresponding to the content displayed on the flexible display unit is displayed (S640). The information menu means a menu for editing, printing, saving, etc. the contents displayed on the flexible display unit. For example, it can act as a right mouse button. The information menu may be displayed to be opaque over the content. On the other hand, if it is determined in step S635 that the touch signal is not inputted through the third area, the content and pointer displayed on the flexible display unit are not changed.

Next, the control unit 180 determines whether there is a signal input through the three areas of the touch screen of the first display unit for a predetermined time (S640). If it is determined in step S640 that there is a signal input through the touch screen of the first display unit for a predetermined time, the content or the pointer is changed according to the input signal (S665), and the content and the pointer are displayed on the flexible display unit ). For example, when a signal is inputted through the first area of the touch screen, the pointer can be moved and displayed. When a signal is inputted through the second area of the touch screen, a menu can be executed and displayed, The information menu for the content can be displayed.
