Abstract

An image display device including a touchscreen display configured to display information; a controller configured to display a touch input window with a predetermined transparency while maintaining the information displayed on the touchscreen display based on a received request, the touch input window including a pad region for controlling a pointer displayed on the touchscreen display, move the pointer displayed on the touchscreen display in accordance with a touch movement on the mouse pad region, select and execute an application corresponding to a display object displayed on the touchscreen display when the pointer is displayed on the display object and an execute command is received, and select and execute the application corresponding to the display object when the pointer is not displayed on the display object and a touch direct input of the display object is received.

Claims

1. An image display device;

comprising;

a touchscreen display configured to display information; and

a controller configured to;

receive a request to display a touch input window on the touchscreen display,

display the touch input window with a predetermined transparency while maintaining the information displayed on the touchscreen display based on the received request, said touch input window including a pad region for controlling a pointer displayed on the touchscreen display,

move the pointer displayed on the touchscreen display in accordance with a touch movement on the pad region of the touch input window,

select and execute an application corresponding to a display object displayed on the touchscreen display when the pointer is displayed on the display object and an execute command is received, and

select and execute the application corresponding to the display object when the pointer is not displayed on the display object and a touch direct input of the display object is received.

2. The image display device of claim 1, wherein the touch input window further includes:

first and second touch click areas to perform additional functions assigned to the first and second touch click areas; and

a preset region to perform moving of the touch input window,

the controller is further configured to move the touch input window corresponding to a touch applied to the preset region of the touch input window.

3. The image display device of claim 2, wherein the controller is further configured to set predefined boundaries of where the touch input window can be displayed on the touchscreen display, and prevent the touch input window from being moved out of the predefined boundaries.

4. The image display device of claim 2, wherein the preset region includes first and second modes, and

wherein the controller is further configured to:

stop displaying the touch input window and the pointer when the preset region is in the first mode and a touch action outside of the touch input window is received, and

continue displaying the touch input window and the pointer when the preset region is in the second mode and the touch action outside of the touch input window is received.

5. The image display device of claim 1, wherein the controller is further configured to display the touch input window and the pointer at locations that have been displayed for a previously received request to display the touch input window.

6. The image display device of claim 2, wherein the first click area of the touch input window executes a double click function for the display object pointed at by the pointer, and the second click area of the touch input window displays a menu for executing at least one function associated with the display object.

7. The image display device of claim 6, wherein the controller is further configured to display a display in a region to which a start point of the first touch input is applied between the first and second click areas, which is visually distinguished from the other region.

8. The image display device of claim 2, wherein a touch action from the first click area to an outside of the first click area is determined as selection of the first click area, and

a touch action from the second click area to an outside of the second click area is determined as selection of the second click area.

9. The image display device of claim 6, wherein the controller is further configured to:

display the first and second click areas to be separated from each other at a preset location of the touchscreen display upon receiving a first input signal,

control to display a pointer moving along the movement of the drag touch input to be displayed in one region of the touchscreen display in response to a drag touch input being sensed in at least one of the first and second click areas, and

control the touchscreen display to contain the first and second click areas within one touch input window upon receiving a second input signal.

10. The image display device of claim 1, further comprising:

a sensing unit configured to sense an orientation of the image display device,

wherein the controller is further configured to display an orientation of the touch input window to match the sensed orientation of the image display device.

11. The image display device of claim 1, wherein the controller is further configured to control to switch a function corresponding to the first touch input executed in the first and second click areas based on setting of the image display device.

12. The image display device of claim 1, wherein the controller is further configured to change a size of the touch input window based on a touch and resizing command.

13. The image display device of claim 12, wherein when the size of the touch input window is a full screen of the touchscreen display,

the controller is further configured to move the pointer to a location of another touch on the touchscreen display, and execute an application corresponding to another display object at the location of said another touch in response to an execute command being received.

14. The image display device of claim 1, wherein the controller is further configured to:

when a touch and drag at a first position inside of the touch input window and to a second position outside of the touch input window is received,

move the pointer displayed on the touchscreen display in accordance with the received touch and drag, and

when a touch and drag of an object at a first position outside of the touch input window, through the touch input window, and to a second position outside of the touch input window is received,

move the object from the first position to the second position, and maintain the display status of the object moving along the touch and drag of the object even when the touch and drag applied to the object displayed outside of the touch input window enters to the touch input window.

15. The image display device of claim 1, wherein the controller is further configured to:

display an indicator icon for adjusting the transparency of the touch input window, and

adjust the transparency of the touch input window according to a manipulation of the indicator icon.

16. The image display device of claim 1, wherein the controller is further configured to display at least one control key associated with the information displayed on the touchscreen display within the touch input window in response to a preset touch being applied to the touch input window.

17. The image display device of claim 1, wherein the controller is further configured to:

display a pop up at least partially over the touch input window, and

selectively deactivate a touch input to a region of the touch input window overlapped with the pop up window.
