5 is a flowchart illustrating a method of operating a portable terminal according to an embodiment of the present invention.

As illustrated in FIG. 5, in the portable terminal in which only the touch screen of the first display unit is exposed in appearance, the flexible display unit disposed in a folded or rolled state in the portable terminal is extended and expanded (S400).

Next, the controller 180 displays an image and a pointer on the flexible display unit, and activates the first display unit to serve as a touch pad (S405). The image and the pointer may be displayed in an appropriate size to correspond to the size of the unfolded area of the flexible display unit. The image may be a web page transmitted from a web server, a broadcast service transmitted through the broadcast receiving module 111, or an execution screen on which a predetermined menu is executed. Therefore, the image includes a video, a photo, text, a text input window, etc., which can be displayed on the flexible display unit. Here, the pointer POINTER is an indicator capable of pointing to a specific area of the image displayed on the flexible display unit. In general, they may be displayed in the form of arrows or fingers.

When an image and a pointer 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 a touch pad of a mouse. In addition, since the flexible display unit has a larger display area than the first display unit, the controller 180 may control the first display unit to act as a touch pad of a mouse with respect to the entire flexible display unit. 1 Scroll bar and scroll area can be displayed on the display. Alternatively, the controller 180 may deactivate the menu icon or the execution screen of the menu displayed on the first display unit in step S400 and use it as a simple touch pad. That is, even when a touch signal for selecting a 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 an image displayed on the flexible display unit. do.

Meanwhile, when the gravity sensor 143 is used, the controller 180 may display an image on the flexible display unit based on the value output from the gravity sensor. For example, when the flexible display unit extends in a parallel direction with respect to the horizontal line, the up-down direction of the displayed image is displayed perpendicular to the extending direction, but when the flexible display unit extends in the vertical direction with respect to the horizontal line, The vertical direction of the image may be displayed horizontally with the extended direction.

Next, the controller 180 determines whether a directional touch signal is input through the touch screen of the first display unit (S410). Hereinafter, an example of a directional touch signal will be described using a drag signal. As a result of determination in S410, when a drag signal is input, the controller 180 moves the pointer to display the flexible display unit in response to the input drag signal (S415). The pointer is moved according to the trajectory of the drag signal, that is, the direction and the moving 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, the area where the drag signal can be input is changed by using the scroll bar and the scroll area displayed on the first display unit, and the drag signal is applied to the changed area. By input, the pointer may be moved over the entire display area of the flexible display unit.

As a result of the determination of S410, when the drag signal is not input or after the pointer is moved and displayed in operation S415, the controller 180 determines whether the pointer is displayed at a position where a text input window for inputting a character is displayed (S420). . That is, it is determined whether the pointer is displayed on the text input window included in the image displayed on the flexible display unit. In the character input window, Korean, numbers, English, special symbols, etc. may be input.

As a result of the determination in S420, when the pointer is displayed in the text input window, the controller 180 displays an editor on the touch screen of the first display unit in operation S425. That is, when the pointer is displayed in an area other than the text input window, the first display unit only serves as a touch pad for moving the pointer. However, when the pointer is displayed on the text input window, the first display unit may input text. It acts as an editor. Editors that can be displayed on the first display unit include a selective editor and a character editor. The selective editor is an editor displayed in the form of a keyboard or a keypad. When the touch signal is input, the selective editor is an editor for inputting characters displayed at the touch input position. The text editor is an editor that converts an input touch signal into a text and inputs the converted text according to the trajectory of the input touch signal. On the other hand, if the pointer is not displayed on the text input window as a result of S420, the screen displayed on the first display unit is not changed. Meanwhile, when the gravity sensor 143 is used, the controller 180 can display an editor on the first display unit based on the value output from the gravity sensor.

Next, the controller 180 determines whether a touch signal is input through the editor displayed on the first display unit in step S425 (S430). As a result of the determination of S430, when a touch signal is input through the editor, the controller 180 displays a character corresponding to the input touch signal in the character input window in which the pointer is displayed (S435). For example, when the selective editor is displayed on the first display unit, a character corresponding to the position at which the touch signal is input is displayed on the character input window, and when the character editor is displayed on the first display unit, according to the trajectory of the touch signal. The converted text is displayed in the text input window. Next, the text input to the text input window is terminated based on the user command (S440). Character input may be terminated through the input character storage icon or the editor end icon. When the text input to the text input window is finished in step S440, the controller 180 ends the display of the editor displayed on the touch screen in step S425 (S445). On the other hand, if the touch signal is not input through the editor as a result of S430, the character is not input to the text input window.
