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 images on a touch screen device provided with a screen comprising a display configured to display the images thereon and a detector configured to detect a touch on the screen, the method comprising:

displaying two or more display windows in a partially overlapped manner; and

if a touch is detected on an underlying display window covered by an overlying display window, changing a display form corresponding to the underlying display window in response to the touch.

2. The method as claimed in claim 1, wherein changing a display form comprising displaying the touched lower display window as an overlying display window.

3. The method as claimed in claim 1, further comprising, if a double touch is detected on the underlying display window covered by the overlying display window, canceling a toggle mode in which the display windows are displayed in an overlapped manner and displaying the double touched underlying display window on the screen in a full size.

4. The method as claimed in claim 3, further comprising, where a toggle mode in which the display windows are displayed in an overlapped manner is canceled and a single display window is displayed on the screen 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.

5. The method as claimed in claim 1, further comprising providing on the overlying display window a toggle mode cancel area for canceling a toggle mode, in which the display windows are displayed in an overlapped manner, when the toggle mode cancel area is touched.

6. The method as claimed in claim 1, further comprising displaying execution menus on the display windows.

7. The method as claimed in claim 6, wherein the execution menus belonging to the same layer are grouped and displayed on the display windows.

8. The method as claimed in claim 7, wherein lower execution menus belonging to a lower layer of the execution menu are displayed on the overlying display window.

9. The method as claimed in claim 6, wherein the execution menus are executed only by a touch input through the overlying display window.

10. A method of displaying images on a touch screen device mounted on digital equipment, comprising the method of claim 1.

11. The method of claim 10, wherein the digital equipment comprises a MP3 player, a portable media player, a portable terminal, a navigation system, or a notebook computer.

12. A touch screen device, comprising:

a screen comprising 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, wherein the controller causes two or more display windows to be displayed in a partially overlapped manner, and if the touch is detected on an underlying display window covered by an overlying display window, a display form corresponding to the underlying display window is changed in response to the touch.

13. The device as claimed in claim 12, wherein when the touch is detected on the underlying display window covered by the overlying display window, the controller causes the underlying display window to be displayed as an overlying display window;

and if a double touch is detected, the controller cancels a toggle mode, in which the display windows are displayed in an overlapped manner, and causes the double touched display window to be displayed on the screen in a full size.

14. The device as claimed in claim 12, wherein the controller causes the overlying display window in the toggle mode to be provided with a toggle mode cancel area for canceling the toggle mode when the toggle mode cancel area is touched, and a display window in a state in which the toggle mode is canceled to be provided with a toggle mode selection area for switching a display mode to the toggle mode when the toggle mode selection area is touched.

15. The device as claimed in claim 12, wherein execution menus displayed on the display windows.

16. The device as claimed in claim 15, wherein execution menus belonging to the same layer are grouped and displayed on one or more display windows displayed in an overlapped manner, and lower execution menus belonging to a lower layer of the execution menu are displayed together on the overlying display window.

17. Digital equipment comprising the touch screen device of claim 12.

18. The digital equipment of claim 17, wherein the digital equipment comprises a MP3 player, a portable media player, a PDA, a portable terminal, a navigation system, or a notebook computer.

20. The digital equipment of claim 18, wherein the digital equipment comprises a MP3 player, a portable media player, a PDA, a portable terminal, a navigation system, or a notebook computer.

19. Digital equipment mounted with a touch screen, the touch screen comprising:

a screen comprising a display configured to display the images thereon and a detector configured to detect a touch on the screen, wherein two or more display windows are displayed in a partially overlapped manner; and

if the touch is detected on an underlying display window covered by an overlying display window, a display form corresponding to the underlying display window is changed in response to the touch.

21. A touch screen device, comprising:

a touch panel for detecting a screen touch;

a touch panel controller configured to signalize the touch detected on the touch panel and controlling the touch panel;

a display configured to display images;

an image storage device configured to store display images; and

a main controller configured to control operations of the touch panel controller and the display, wherein the main controller allows two or more display windows to be displayed in a partially overlapped manner and allows a display form to be changed corresponding to an underlying display window if the touch is detected on the underlying display window covered by an overlying display window.

22. The device as claimed in claim 21, wherein the image storage device is a NOR flash memory.

23. The device as claimed in claim 22, further comprising:

a USB port connected to an external device configured to update or modify the image information stored in the image storage device.

24. The device as claimed in claim 21, further comprising:

a data storage device configured to store data of the touch screen device; and

a RAM configured to drive the touch screen device.

25. The device as claimed in claim 24, wherein a portion of the data storage device is configured into the image storage device.

26. The device as claimed in claim 21, wherein when the touch is detected on the underlying display window covered by the overlying display window, the main controller causes the underlying display window to be displayed as an overlying display window;

and if a double touch is detected, the main controller cancels a toggle mode, in which the display windows are displayed in an overlapped manner, and causes the double touched display window to be displayed on the screen in a full size.

27. The device as claimed in claim 21, wherein the main controller causes the overlying display window in the toggle mode to be provided with a toggle mode cancel area for canceling the toggle mode when the toggle mode cancel area is touched, and a display window in a state where the toggle mode is canceled to be provided with a toggle mode selection area for switching a display mode to the toggle mode when the toggle mode selection area is touched.
