However, these sensors are provided in one embodiment of the sensor unit 100, and other sensors, mechanisms or devices may also be used to detect the panning, tilting, and/or rotating operation of the touch display apparatus 1.

[0031] The user interface unit 200 may be implemented as a touch screen. The touch screen can directly receive input information on the screen so that when a hand or other objects touches a character displayed on the screen, or a specific position on the screen, a specific process is performed by stored software in accordance with the touched character or position.

[0032] The touch screen is capable of performing functions by attaching a touch panel to a screen of a general monitor. A plurality of infrared grids are formed on the screen so that a position of the screen can be determined when a finger tip or other objects touches the grid.

[0033] When a hand touches character or picture information displayed on the screen mounted with the touch panel, the selected item is understood according to the touched position and a command corresponding to the selected item is processed by a computer, enabling a user to readily obtain desired information.

[0034] The user interface unit 200 outputs a touch signal the control unit 400.

[0035] Further, the user interface unit 200 may display various kinds of screens. More specifically, the user interface unit 200 may display a background screen, which displays GUI items, such as icons indicating a plurality of applications.

[0036] The user interface unit 200 can receive instructions from the control unit 400 to display a display screen of an application currently being executed, a web browser screen, a screen corresponding to a multimedia file, or the like.

[0037] The storage unit 300 stores graphic data required to implement a screen displayed on the user interface unit 200. The storage unit 300 provides the stored graphic data to the control unit 400 in accordance with control commands of the control unit 400.

[0038] Further, the storage unit 300 may further store graphic data required to implement a new screen generated by the control unit 400.

[0039] The storage unit 300 may also store various kinds of application programs, a web browser, and multimedia files.

[0040] The control unit 400 may control an overall operation of the sensor unit 100, the user interface unit 200 and the storage unit 300.

[0041] The control unit 400 detects an operation to enter an edit mode when a preset edit mode entering operation is input to the user interface unit 200. The control unit 400 controls the user interface unit 200 to display a screen corresponding to an edit mode, i.e., a screen indicating the edit mode state.

[0042] In the edit mode, a GUI item, text, an image or the like, which are displayed on a background screen or a web browser screen may be moved to other background screens, other web browser screens, or the like.

[0043] In the edit mode entering operation, a GUI item, text or an image to be moved is designated simultaneously with entry to the mode. In an embodiment of the present invention, various edit mode entering operations are implemented, and the operations are described in greater detailed with respect to FIGS. 3A-3C.

[0044] The GUI item, text, or image to be moved, is commonly referred to as target edit content.

[0045] The screen indicating the edit mode state may be stored in the storage unit 300 in graphic data form. The control unit 400 may generate the screen indicating the edit mode state using graphic data, after the control unit 400 reads the graphic data for a background screen display from the storage unit 300.

[0046] The control unit 400 may generate graphic data for forming a corresponding screen based on a degree or direction of movement of the touch display apparatus 1 detected from the sensor unit 100. In addition, the control unit 400 may control the storage unit 300 to store the graphic data.

[0047] The control unit 400 may control the user interface unit 200 to display the corresponding screen using the graphic data generated on the basis of the motion of the touch display apparatus 1.

[0048] In particular, the control unit 400 may control the user interface unit 200 to display a screen converted according to the degree or direction of the motion of a panning, tilting or rotating of the touch display apparatus 1.

[0049] While the screen converted according to the degree or direction of the motion of the touch display apparatus 1 is displayed on the user interface unit 200, when a user inputs an edit mode releasing operation to the user interface unit 200, the control unit 400 controls the user interface unit 200 to end the edit mode with the target edit target content displayed on the converted screen.

[0068] As described above, the user can designate the target edit content and simultaneously enter the edit mode in various manners. In addition, the user can use a background screen including icons as well as a web browser screen as the edit target.

[0069] FIG. 4 is a diagram illustrating a display edit process of the touch display apparatus 1, according to an embodiment of the present invention.

[0070] The user interface unit 200 displays a background screen that includes a plurality of application identification icons. As shown in FIG. 4, a user may touch a specific icon displayed on the user interface unit 200. The operation is the same as that described with reference to FIG. 3A. The user designates the bottom rightmost icon of the plurality of application identification icons as an edit target icon and simultaneously enters an edit mode.

[0071] The number “1”, which is displayed at the top left portion of the user interface unit 200 is a page identification number ‘a’ indicating that a background screen that is currently displayed on the user interface unit 200.

[0072] The user may perform an operation of panning the touch display apparatus 1 to the right. When the sensor unit 100 detects that the touch display apparatus 1 is panned over a preset distance threshold value, the control unit 400 controls the user interface unit 200 to display a new screen, which now includes the target edit content, corresponding to the panning distance of the touch display apparatus 1.

[0073] In the embodiment of the present invention illustrated in FIG. 4, the user pans the touch display apparatus 1 to the right approximately twice the preset distance threshold value, and the sensor unit 100 detects the panning distance and direction and transmits the detected distance and direction to the control unit 400.

[0074] The control unit 400 controls the user interface unit 200 to display the new screen, with the target edit content, based on the information received from the sensor unit 100.

[0075] More specifically, the control unit 400 may form the new screen based on the background screen that is 2 pages from the initial page 1 in a right direction, i.e., page 3, since the touch display apparatus 1 is panned more than twice but less than thrice the distance threshold value to the right. More generally, the control unit 400 generates the new screen from a menu screen that is n pages from the initial display page, when the panning distance of the touch display apparatus 1 is more than n times and less than n+1 times the distance threshold value. Here, n is natural number.

[0076] As described above with reference to FIG. 2, the GUI generation unit 430 may read the third page from the storage unit 300 and generate a new screen that includes the target edit target in the third page.

[0077] A page identification number ‘b’ of the new screen of FIG. 4 is ‘3’. The new page is generated having the target edit contend included in background screen 3, which is 2 pages from an original background screen to the right.

[0078] After the new screen is generated, the user may perform an edit mode releasing operation for releasing the edit mode. The edit mode releasing operation of the user may be when the touch is released. The edit mode releasing operation may also be signified by touching a portion of the background other than the previously selected GUI item. However, any number of methods may be used to signify the above-described edit mode releasing operation.

[0079] When the edit mode releasing operation is input to the user interface unit 200, the control unit 400 controls the user interface unit 200 to end the edit mode and display the target edit target in its current position. The control unit 400 may control the user interface unit 200 so that an edit-related function is not displayed even when the edit-related operation is input to the user interface unit 200.

[0080] The effect resulting from panning the touch display apparatus 1 to right may also result from panning the touch display apparatus 1 upwards or downwards. Further, the control unit 400 may control the user interface unit 200 so that the process of changing from a previous screen to next screen is identified by the user before the new screen is displayed on the user interface unit 200.

[0081] For example, the user interface unit 200 may display that the previous edit mode screen is gradually converted into the next edit mode screen while sliding or scrolling the previous edit mode screen according to the degree and direction of the motion.

[0082] The screen being displayed on the user interface unit 200 during the conversion process may be a screen having a portion of the previous edit mode screen and a portion of the next edit mode screen. Further, the screen being displayed during the conversion process may be a display screen between the previous edit mode screen and the next edit mode screen, for example, page 2.

[0083] The control unit 400 may determine a speed of sliding or scrolling based on the degree of the motion. For example, when the user pans the touch display apparatus 1 at fast speed, the control unit 400 may control the user interface unit 200 to display sliding at fast speed.

[0084] In addition, the control unit 400 may determine the speed of sliding or scrolling as proportional to the panning distance.

[0085] According to the above-described embodiments of the present invention, the user may pan the touch display apparatus 1 to edit the background screen including the application identification icon.
