Abstract

A touch screen device and method of displaying images using display windows and selecting execution menus displayed on the display windows in a touch screen device are provided. The touch screen device includes a screen, a display configured to display images thereon and a detector configured to detect a touch on the screen, and a controller configured to control operation of the touch screen device in accordance with the screen touch detected by the detector. The controller causes two or more display windows to be displayed in an overlapped manner. Further, if the touch is detected on an underlying display window covered by an overlying display window, the controller causes a display form to be changed in response to the touch. That is, if a touch is detected on the display window covered by the overlying display window, the touched display window is displayed as an overlying display window

Claims

1. A method of displaying a plurality of menu pages on a touch screen device having a touch screen display having a predetermined viewing area and a detector configured to detect a touch on the touch screen display and a controller configured to control operation of the touch screen device in accordance with the screen touch detected by the detector, the method comprising:

displaying the plurality of menu pages in an overlapped manner, each of the plurality of menu pages having a title and a plurality of menu execution portions, wherein a title and the plurality of menu execution portions are displayed for an uppermost displayed menu page and only the title is displayed for the underlying menu pages; and

if a touch is detected by the detector on a surface of the touch screen display, changing the uppermost displayed menu page.

2. The method as claimed in claim 1, wherein the title is displayed at a substantially topmost position on the uppermost displayed menu page.

3. The method as claimed in claim 1, wherein changing the uppermost displayed menu page comprises displaying one of the underlying menu pages as an uppermost displayed menu page.

4. The method as claimed in claim 1, further comprising, if a double touch is detected by the detector on one of the underlying menu pages covered by the uppermost displayed menu page, canceling a toggle mode in which the menu pages are displayed in an overlapped manner and displaying the double touched underlying menu page on the touch screen display in a full size.

5. The method as claimed in claim 4, further comprising, where a toggle mode in which the menu pages are displayed in an overlapped manner is canceled and a single display window is displayed on the touch screen display in a full size when the toggle mode cancel area is touched, providing a toggle mode selection area for switching a display mode to the toggle mode when the toggle mode selection area is touched on the single display window.

6. The method as claimed in claim 1, further comprising providing on the uppermost displayed menu page a toggle mode cancel area for canceling a toggle mode, in which the menu pages are displayed in an overlapped manner, when the toggle mode cancel area is touched.

7. A method of displaying a plurality of menu pages on a touch screen device mounted on digital equipment, comprising the method of claim 1.

8. The method of claim 7, wherein the digital equipment comprises a MP3 player, a portable media player, a portable terminal, a navigation system, or a notebook computer.

12. The touch screen device as claimed in claim 1, wherein, if a double touch is detected by the detector on one of the underlying menu pages covered by the uppermost displayed menu page, the controller cancels a toggle mode in which the menu pages are displayed in an overlapped manner and displays the double touched underlying menu page on the touch screen display in a full size.

13. The touch screen device as claimed in claim 4, wherein, where a toggle mode in which the menu pages are displayed in an overlapped manner is canceled and a single display window is displayed on the touch screen display in a full size when the toggle mode cancel area is touched, the controller provides a toggle mode selection area for switching a display mode to the toggle mode when the toggle mode selection area is touched on the single display window.

14. The touch screen device as claimed in claim 1, wherein the controller provides on the uppermost displayed menu page a toggle mode cancel area for canceling a toggle mode, in which the menu pages are displayed in an overlapped manner, when the toggle mode cancel area is touched.

9. A touch screen device configured to display a plurality of menu pages, the touch screen device comprising:

a touch screen display having a predetermined viewing area;

a detector configured to detect a touch on the touch screen display; and

a controller configured to control operation of the touch screen device in accordance with the screen touch detected by the detector, wherein the controller displays the plurality of menu pages on the touch screen display in an overlapped manner, each of the plurality of menu pages having a title and a plurality of menu execution portions, wherein a title and the plurality of menu execution portions are displayed for an uppermost displayed menu page and only the title is displayed for the underlying menu pages, and wherein if a touch is detected by the detector on a surface of the touch screen display, the controller changes the uppermost displayed menu page.

10. The touch screen device as claimed in claim 9, wherein the title is displayed at a substantially topmost position on the uppermost displayed menu page.

11. The touch screen device as claimed in claim 9, wherein the controller changes the uppermost displayed menu page by displaying one of the underlying menu pages as an uppermost displayed menu page.

15. Digital equipment, comprising the touch screen device of claim 9.

16. The touch screen device of claim 15, wherein the digital equipment comprises a MP3 player, a portable media player, a portable terminal, a navigation system, or a notebook computer.
