9, the control unit 407 displays the folder 9-1 in the first horizontal area 7-1 of the file browser, and displays the folder 9-1 in the second horizontal area 7-2. (E.g., a thumbnail image corresponding to the image file, a thumbnail image corresponding to the music file, or a thumbnail image corresponding to the moving image file) 9-2 in the folder 9-1. For example, when the user selects a specific folder through the up or down key or the touch sensor, the control unit 407 displays data in the selected folder in the second horizontal area do. Here, the subfolders and files included in the folder in the first horizontal area are displayed in the second horizontal area. Therefore, the user can easily and effectively search the folder and the file by displaying the folder and data in the horizontal area so that the user can see the image horizontally.

The control unit 407 determines whether the data (for example, a thumbnail image) in the folder 9-1 exceeds a predetermined value (for example, a predetermined number) (S15) (9-3) of the excess data is displayed at the end of the second horizontal area when the data in the first horizontal area exceeds the preset value (S16). For example, the control unit 407 may set thumbnail images corresponding to the image files in the folder 9-1 to a predetermined number (for example, only five thumbnail images) in the second horizontal area By selecting any one of the excess thumbnail images when it can not be displayed in excess and displaying one half of the selected image at the left and right ends of the second horizontal area, It can be seen that there are more image files. The control unit 407 may move data (for example, an image file) according to the movement position of the cursor.

The control unit 407 may display various files included in the folder in various manners. That is, the control unit 407 can easily identify a file included in the folder by displaying the outer circumference of the thumbnail image variously according to the characteristics of each file so that the user can easily distinguish the files included in the folder without viewing the extension .

14, when the control unit 407 displays a picture file in a file browser, the control unit 407 displays a specific key (for example, the left or right side of the mouse, Key) is selected by the user, the size of the thumbnail image corresponding to the photo file is enlarged by a predetermined size (for example, 2 times) and displayed (14-1). In addition, when the user selects the specific key again, the controller 407 displays the size of the thumbnail image corresponding to the photo file in a predetermined size (for example, original size (1 time)) Many photo files can be displayed (14-2).

15 is a diagram illustrating a method of displaying a music file according to a fourth embodiment of the present invention.

As shown in FIG. 15, when the music file is displayed on the file browser, the control unit 407 displays a music file name in a file browser, Or the right key) is selected by the user, the music file name is displayed in the thumbnail image corresponding to the music file long (for example, 10 to 15 characters). At this time, the controller 407 may enlarge the size of the thumbnail image corresponding to the music file by a predetermined size (for example, 2 times) (15-1).

Further, when the user selects the specific key again, the controller 407 displays the music file name of the thumbnail image corresponding to the music file shortly (for example, within 10 characters). At this time, the control unit 407 can display a large number of music files by displaying the size of the thumbnail image corresponding to the music file in a predetermined size (for example, original size (1x)) (15-2 ).

16 is a diagram showing a display method of a movie (e.g., movie) file according to the fourth embodiment of the present invention.

16, when the user displays a movie file in a file browser, the controller 407 displays a specific file (for example, a left mouse button Or right key) is selected by the user, the movie file name is displayed on the thumbnail image corresponding to the movie file for a long time (for example, 10 to 15 characters). At this time, the controller 407 may enlarge the size of the thumbnail image corresponding to the movie file by a predetermined size (for example, double) (16-1).

Further, when the user selects the specific key again, the controller 407 displays the movie file name of the thumbnail image corresponding to the movie file shortly (e.g., within 10 characters). At this time, the controller 407 can display a number of movie files by displaying a thumbnail image corresponding to the movie file in a predetermined size (for example, original size (1x)) (16- 2).

Hereinafter, a method of effectively displaying data (e.g., a thumbnail image corresponding to a photograph, a moving image, or a music file) will be described with reference to Figs. 5 and 17. Fig.

17 is a view illustrating a thumbnail image display method according to a fifth embodiment of the present invention.

First, the control unit 407 determines whether a thumbnail image exists in a corresponding item (e.g., a picture, a moving picture, or a music file) (S21).

If a thumbnail image exists in a corresponding item (e.g., a picture, a moving picture, or a music file), the controller 407 assigns a number to each thumbnail image (S22).

The controller 407 assigns a number to the thumbnail image, and then stores the thumbnail image in the storage unit 404 automatically. Here, the controller 407 automatically stores the thumbnail image in the storage unit 404 when there is no input from the user (S23).

The control unit 407 reads out (reads) a thumbnail image corresponding to the user request from the storage unit 404 (S25) when the user requests it (S24), and transmits the read thumbnail image to the display unit 405 (S26). That is, since the thumbnail image is previously stored in the storage unit 404 rather than the time for extracting the thumbnail image from the item, the time for reading and displaying the thumbnail image from the storage unit 404 according to the user's request is faster, And the corresponding thumbnail image can be displayed on the display unit 405.

When the data capacity of the thumbnail image to be stored in the storage unit 404 exceeds the storage capacity of the storage unit 404 (S27), the control unit 407 stores the thumbnail image number The thumbnail image initially connected according to the connection order is deleted from the storage unit 404 (S28). For example, the control unit 407 assigns a low value to a thumbnail image that has been most recently accessed, gives a high value to files that have been accessed for a long time, and then, when the storage capacity of the storage unit is exceeded, A thumbnail image is deleted from the storage unit 404, and a new thumbnail image is stored in the storage unit 404. That is, it is possible to effectively manage data (for example, a thumbnail image) by preventing a problem caused by the limitation of the storage capacity of the storage unit 404 of the data display device.

As described in detail above, the data display method and apparatus according to the embodiments of the present invention divide the display area of the file viewer into a plurality of horizontal areas, display a folder in the first horizontal area, By displaying the data contained in the folder in the horizontal area, the user can easily and effectively search the files and folders.

The data display method and apparatus according to the embodiments of the present invention can display a file corresponding to a file differently according to the file type, thereby enabling a user to search for the file easily and effectively.

The data display method and apparatus according to embodiments of the present invention can effectively manage data by selectively deleting data according to the storage capacity of the storage unit.

Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the essential characteristics of the invention.
