Button, video call button, item edit button, item delete button, item add button, etc.) are displayed.

In this case, when all of the execution buttons 450 cannot be displayed in the extended area 440, the controller 180 is displayed at the left (or right) end as shown in a) of FIG. 7. Process the button (eg delete button) so that only a portion of it appears on the screen, as if it was cut off by the screen.

The execution button 450 executes each assigned function, and may be displayed in different sizes as shown in b) of FIG. 7 according to the importance (or priority, frequency of use) of the corresponding function.

The user can intuitively know which execution button can be executed in the corresponding list item or the frequency of use through the execution buttons of different sizes.

8 is an exemplary view illustrating a method of displaying an execution button usable in an expanded list item.

As described above, when an item including detailed information (eg, 'List 7') is selected, the controller 180 expands the area of the selected item (eg, 'List 7') and expands the expanded area 440. The execution buttons 450 are displayed at the bottom (bottom) of the.

The expanded area 440 is moved according to a user's manipulation (eg, key input or touch input (eg, dragging, flicking, etc.)). Even in this case, the controller 180 controls the execution buttons 450 not to disappear from the screen while placing the execution buttons 450 at the lower end (bottom portion) of the extended area 440. The execution buttons 450 do not disappear from the screen until the enlarged area 440 is reduced, that is, until it returns to its original state.

9 is an exemplary view illustrating a display method of a scroll bar according to the present invention.

As shown in FIG. 9, in outputting a list of various contents of the terminal, the controller 180 does not display a scroll bar until a separate external input (eg, a user's touch input) is detected. Of course, the scroll bar is not displayed even if the number of items in the list does not exceed one screen.

If an external input (eg, a user's touch input) is detected on the touch screen, the controller 180 displays a scroll bar on the screen. When the detected user's touch disappears, the scroll bar is controlled to disappear from the screen after a predetermined time elapses.

When the user wants to scroll the list, the user may grab the scroll bar displayed on the screen and scroll in the desired direction before the predetermined time elapses after touching the screen.

As described above, the list display method according to each embodiment of the present invention can be embodied as computer readable codes on a medium on which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and are also implemented in the form of a carrier wave (for example, transmission over the Internet). It includes being. The computer may include the controller 180 of the mobile terminal.

In the present invention, when the list item includes detailed information (or sub-items), the area of the corresponding item is expanded, thereby eliminating the inconvenience of opening a new window or switching the screen. The present invention allows a user to manipulate a user interface (UI) with psychological stability.

In addition, the list display method according to the present invention implements so that the user can intuitively know whether there are more items other than the list items displayed on the screen, thereby increasing the convenience of the terminal user and fully utilizing the limited space of the terminal screen. The presentation method is presented.
