Abstract

A portable terminal for sensing a touch input, including a direct touch input and a proximity touch input, includes a touch screen configured to receive the touch input via a touching object and responsively displaying at least a first portion of a page and a controller configured to recognize the direct touch input when the touching object contacts the touch screen and recognize the proximity touch input when the touching object is located within a threshold distance relative to the touch screen for a period of time, the proximity touch input being effective as long as the touching object remains within the threshold distance, wherein in response to the proximity touch input, a size of the displayed page is changed from a first size to a second size, or a second portion of the page is displayed on the touch screen, the second portion being different from the first portion.

First claim

What is claimed is:

1. A method for controlling display in a mobile terminal, the method comprising:
displaying a first object on a touchscreen of the mobile terminal, the first object including at least one first sub-object;
receiving a first proximity touch input over the first object by a touch media for a prescribed time;
displaying at least one preview image corresponding to the at least one first sub-object on the touchscreen while the touch media maintains the first proximity touch input;
receiving a second proximity touch input over a second object on the touchscreen, the second object including at least one second sub-object, wherein the second proximity touch input comprises the touch media moving from a first position of the second object to a second position of the second object while the touch media maintaining a distance from the touch screen; and
displaying at least one preview image corresponding to the at least one second sub-object on the touchscreen while the touch media maintains the second proximity touch input,
wherein the second object overlaps a portion of the first object, and
wherein the second object includes an entire area of the first object in a reduced size.

2. The method of claim 1 , wherein the at least one second sub-object is displayed on an area adjacent to the first object on the touchscreen.

3. The method of claim 1 , wherein the at least one second sub-object is displayed such that the at least one second sub-object overlaps the first object on the touchscreen.

4. The method of claim 1 , wherein the at least one first sub-object is displayed on an entire area of the touchscreen.

5. The method of claim 1 , wherein the at least one first sub-object is displayed in a slide format.

6. The method of claim 1 , wherein each of the first object and the second object includes an icon corresponding to a prescribed web-page, and each of the first sub-object and the second sub-object includes a browser to the prescribed web-page.

7. The method of claim 1 , further comprising:
receiving a first touch input on one of the at least one preview image corresponding to the at least one first sub-object; and
displaying the first sub-object whose preview image receives the first touch input on the touchscreen.

8. The method of claim 7 , wherein the first sub-object whose preview image receives the touch input is displayed on an entire area of the touchscreen.

9. The method of claim 1 , further comprising:
recognizing that the first proximity touch input is being released; and
terminating display of the at least one preview image corresponding to the at least one first sub-object.

10. The method of claim 1 , further comprising:
receiving a first touch input on the preview image corresponding to the at least one first sub-object which receives a third proximity touch input; and
displaying the first sub-object whose preview image receives the first touch input as a wallpaper on the touchscreen.

11. The method of claim 1 , wherein the first object includes an image folder and the first sub-object includes an image in the image folder.

12. The method of claim 1 , wherein the second object further includes a scroll box indicating a portion of the at least one preview image corresponding to the at least one second sub-object that is currently displayed on the touchscreen.

13. The method of claim 12 , wherein the at least one preview image corresponding to the at least one second sub-object is scrolled according to movement of the scroll box that is caused by the movement of the touch media.

14. A mobile terminal comprising:
a touchscreen configured to display a first object including at least one first sub-object; and
a controller configured to:
receive a first proximity touch input over the first object by a touch media for a prescribed time;
control the touchscreen to display at least one preview image corresponding to the at least one first sub-object while the touch media maintains the first proximity touch input;
receive a second proximity touch input over a second object on the touchscreen, the second object including at least one second sub-object, wherein the second proximity touch input comprises the touch media moving from a first position of the second object to a second position of the second object while the touch media maintaining a distance from the touch screen; and
control the touchscreen to display at least one preview image corresponding to the at least one second sub-object while the touch media maintains the second proximity touch input,
wherein the second object overlaps a portion of the first object, and
wherein the second object includes an entire area of the first object in a reduced size.

15. The mobile terminal of claim 14 , wherein the controller is further configured to control the touchscreen to display the at least one second sub-object adjacent to the first object on the touchscreen.

16. The mobile terminal of claim 14 , wherein the controller is further configured to control the touchscreen to display the at least one second sub-object such that the at least one second sub-object overlaps the first object.

17. The mobile terminal of claim 14 , wherein the controller is further configured to control the touchscreen to display the at least one first sub-object on an entire area of the touchscreen.

18. The mobile terminal of claim 14 , wherein the controller is further configured to control the touchscreen to display the at least one first sub-object in a slide format.

19. The mobile terminal of claim 14 , wherein the controller is further configured to:
receive a first touch input on one of the at least one preview image corresponding to the at least one first sub-object; and
control the touchscreen to display the first sub-object whose preview image receives the first touch input.

20. The mobile terminal of claim 19 , wherein the controller is further configured to control the touchscreen to display the first sub-object whose preview image receives the touch input on an entire area of the touchscreen.

21. The mobile terminal of claim 14 , wherein the controller is further configured to:
recognize that the first proximity touch input is being released; and
control the touchscreen to terminate display of the at least one preview image corresponding to the at least one first sub-object.

22. The mobile terminal of claim 14 , wherein the controller is further configured to:
receive a first touch input on the preview image corresponding to the at least one first sub-object which receives a third proximity touch input; and
control the touchscreen to display the first sub-object whose preview image receives the first touch input as a wallpaper.

23. The mobile terminal of claim 14 , wherein the first object includes an image folder and the first sub-object includes an image in the image folder.
