Here, an example of the key input unit 100 refers to up, down, left and right manipulation key buttons provided in the mobile devices. When the user manipulates the up, down, left and right manipulation key buttons, the key input unit 100 outputs the input signal to the controller 120 in response to the user's manipulation.

The control unit 120 controls the graphic user interface unit 140 to move the virtual display screen up, down, left, and right and display it on the display window in response to an input signal of the key input unit 100. For example, if the signal input from the key input unit 100 is the signal of the left and right operation buttons, the graphic user interface unit 140 is instructed to move and display the virtual display screen as much as the left and right operation buttons. In addition, if the signal input from the key input unit 100 is a signal of the up / down operation button, the graphic user interface unit 140 is instructed to move and display the virtual display screen by the amount corresponding to the up / down operation button.

The graphical user interface unit (GUI) 140 generates a virtual display screen that is at least larger than the display window and displays the generated virtual display screen on the display window.

2 is a diagram illustrating an example of a display window and a virtual display screen. As shown in FIG. 2, it can be seen that the virtual display screen is larger than the actual display window size in the mobile device. As such, the graphical user interface unit GUI generates a virtual display screen that is at least larger than the display window.

When the controller 120 is instructed to display the screen according to the left and right or up and down movement of the virtual display screen, the graphic user interface unit 140 displays some screens of the virtual display screen corresponding to the movement instruction in the display window. An example of some screens of the virtual display screen may be a screen corresponding to a specific item, as shown in FIG. 2.

The graphic user interface 140 may distinguish the selected item from the virtual display screen from other items and display the distinguished item. As shown in FIG. 2, the item ① of the artist named "Boa" is displayed separately from other items. In such a display method, a method of changing colors may be used, or the size of an icon representing an item may be enlarged and displayed.

FIG. 3 is a diagram illustrating an example of displaying the virtual display screen illustrated in FIG. 2 on a display window according to a user's key manipulation. First, FIG. 2A shows that the first screen set as a default is displayed on the display window. At this time, the item of the artist "Boa" corresponding to the first item (Artist) is displayed to be distinguished from other items. In addition, the text for the item is also displayed. When the user operates the right button through the key input unit 100, the artist lists are highlighted in sequence as shown in FIG. At this time, the virtual display screens that are out of the display window are scrolled horizontally and sequentially displayed on the screen. Meanwhile, when the user manipulates the down button through the key input unit 100, as shown in FIGS. 2C and 2D, a category corresponding to the item is displayed. That is, a list corresponding to the album, genre, etc. as a category for the item "Boa" is sequentially displayed on the display window according to the operation of the down button. When the user operates the OK button, as shown in FIG. 4E, items (songs) corresponding to the genre selected from the artist Boa and the album (1 single album) are displayed at the top.
