4, when a menu including an input window for inputting a character is selected, the controller 180 displays a screen including one or more input windows included in the selected menu as a display including a touch screen And displays it on the display unit 151 (S400). Here, the term " character " means numbers, Hangul characters, alphabets, symbols, special characters, and the like. Next, the control unit 180 determines which one of the one or more displayed input windows is selected (S405). That is, it is determined whether a touch signal, a drag signal, a flick signal, or the like is input through one of the one or more input windows. As a result of the determination in step S405, if one input window is not selected, the control unit 180 holds the display of one or more input windows on the display unit 151 (S400), and waits until one input window is selected .

If it is determined in operation S405 that the input window is selected, the control unit 180 displays the keypad input window corresponding to the selected input window on the display unit 151 (S410). In addition, the controller 180 can display the screen in which only the corresponding keypad input window is displayed so as to share a part or all of at least one side with the upper, lower, left, and right sides of the screen in which the one or more input windows are displayed. For example, when the keypad input window is displayed as a rectangle, the screen displaying only the keypad input window may share the lower side of the screen in which one or more input windows are displayed, and one or more input windows may be displayed to share a part of the left and right sides of the displayed screen .

The keypad input window corresponding to the selected input window is a keypad input window for displaying characters mainly used in the selected input window, and can be freely changed by the setting. For example, if the selected input window is an email input window in which alphabetic characters are mainly input, the keypad input window corresponding to the selected input window is a keypad input window for displaying alphabetic characters. Also, when a number is mainly inputted to the selected input window, the corresponding keypad input window may be a keypad input window for displaying a number. When an image is mainly input in the selected input window, the corresponding keypad input window can display a list of images or a gallery listing the images themselves. In step S410, the control unit 180 may display a part or all of the keypad input window on the display unit 151, and may display only the boundary area included in the keypad input window on the display unit 151. [ The border area is an area included in the keypad input window, and can be displayed in various forms. For example, the border area can be displayed as a tab in the keypad input window. The border area of the keypad input window displayed in S410 is always displayed on the display unit 151 except when an input for ending display of the keypad input window occurs.

Next, the control unit 180 determines whether a character is input through the keypad input window displayed in step S410 (S415). As a result of the determination in step S415, if a character is input, the control unit 180 displays the input character on the selected input window displayed on the display unit 151 (S420). Here, the controller 180 determines that the one character is input only when the touch signal is input through one character included in the keypad input window and ends through the one character, and displays the character on the display unit 151 Display.

If it is determined in step S415 that the character is not input or after the character is input in step S420, the control unit 180 determines whether an area other than the one or more input windows and the keypad input window displayed on the display unit 151 is selected (S425). That is, the controller 180 determines whether an input for terminating the display of the keypad input window is received by inputting a touch signal, a drag signal, a flick signal, or the like through an area other than the one or more input windows and the keypad input window. If it is determined in step S425 that the area other than the one or more input windows and the keypad input window is selected, the controller 180 terminates the display of the keypad input window (S430), and one or more input windows are displayed on the display unit 151 (S400).

If an area other than the one or more input windows and the keypad input window is not selected as a result of the determination in step S425, the controller 180 determines whether a drag signal in the first direction is inputted through the displayed keypad input window at step S435. Here, the first direction may be defined as a left-right direction around a screen on which at least one input window is displayed. In addition, a point where the input of the drag signal in the first direction starts is a point included in an area other than the border area. Also, unlike the case where a character is input through the keypad input window in step S415, the drag signal is started through one character included in the keypad input window and terminated through another character included in the keypad input window Can be defined as a drag signal in the first direction.

If it is determined in step S435 that the drag signal in the first direction is input, the controller 180 terminates the display of the displayed keypad input window, and displays a keypad input window including the displayed character string on the display unit 151 (S440). For example, when a drag signal in the first direction is inputted through a keypad input window including a number, display of a keypad input window including numbers is terminated, and a keypad input window including a Korean character string is displayed. Here, the size of the newly displayed keypad input window may be the same as the size of the completed keypad input window. Next, the control unit 180 determines whether a character is input through the newly displayed keypad input window (S415), and then performs steps S425 and S435.

On the other hand, if it is determined in step S435 that the drag signal in the first direction is not input, the control unit 180 determines whether a signal for dragging the border area of the keypad input window, which is parallel to one side shared with the displayed screen, Is input (S445). If it is determined in step S445 that the drag signal is not input, the control unit 180 determines whether a character is input through the displayed keypad input window (S415), and then performs steps S425, S435, and S445.

On the other hand, if it is determined in step S445 that the drag signal is input, the control unit 180 moves the border area in parallel with the shared side according to the drag signal, And displays the keypad input window in the area between the keypad input window and the keypad input window (S450).

In step S450, the keypad input window may be displayed in various ways. For example, when a region in which a keypad input window is displayed is expanded as a result of dragging a boundary region, a keypad input window is displayed based on the boundary region, and a new character string is displayed in a keypad input window Alternatively, a keypad input window may be displayed on the basis of the shared side, and a new character string may be displayed on the keypad input window that touches the boundary area. In another embodiment of the present invention, when a region in which a keypad input window is displayed is reduced as a result of a dragging of a boundary region, a keypad input window is displayed based on the boundary region, The display of the character string displayed on the keypad input window touching the keypad input window may be terminated or the keypad input window may be displayed on the basis of the shared side so that the display of the character string displayed on the keypad input window, Can be terminated.

Next, the control unit 180 determines whether a character is input through the keypad input window displayed in step S450 (S415), and then performs steps S425, S435, S445, and S450.

When the displayed keypad input window is terminated and another input window is selected, steps S410 to S450 may be repeated. However, if another input window is selected without ending the displayed keypad input window, a kind of indication that a cursor movement or a character can be input is moved between input windows, and the display of the keypad input window already displayed may not be changed. For example, when an email input window is selected and a keypad input window of a corresponding English character string is displayed on the display unit 151, when a number input window is selected, the control unit 180 displays a keypad input window of a numeric character string corresponding thereto, The keypad input window of the English character string may be displayed on the display unit 151 as it is. If the keypad input window of the English string is displayed as it is, the user can change the keypad input window through the drag input in the first direction in step S435. The keypad input window displayed in S410 to S450 may be displayed transparently so as to overlap with one or more input windows.
