Abstract

A mobile terminal and controlling method thereof are disclosed. The present invention includes displaying an e-book content on a touchscreen, determining whether a touch lock prerequisite for setting the touchscreen to a touch lock mode is met, and if the touch lock prerequisite is met, setting the touchscreen to the touch lock mode. If the touchscreen is set to the touch lock mode, the touchscreen maintains a locked status for a touch action except a specifically provided touch action. And, the touchscreen set to the touch lock mode is set to display the e-book content.

First claim

What is claimed is:

1. A method of controlling a mobile terminal comprising:
displaying a first specific page of e-book content comprising a plurality of pages on a touchscreen that is in a touch unlock mode;
causing the touchscreen, on which the first specific page is displayed, to enter a touch lock mode;
displaying the first specific page on the touchscreen that entered the touch lock mode; and
causing the touchscreen to exit the touch lock mode and display a next or previous page of the e-book content in response to receiving a drag input in a first direction at the touchscreen that is in the touch lock mode.

2. The method of claim 1 , further comprising:
displaying a memo icon on the touchscreen while the touchscreen is in the touch lock mode;
activating a memo application in response to receiving a touch input selecting the memo icon via the touchscreen;
receiving a handwriting touch input via the touchscreen to the memo application for drawing a handwriting object; and
displaying the handwriting object with a path of the handwriting touch input on the first specific page of the e-book content.

3. The method of claim 1 , wherein the touchscreen enters the touch lock mode when not receiving an input of a touch action for a threshold time duration during the touch unlock mode or when receiving a user command to lock the touchscreen.

4. The method of claim 1 further comprising, displaying the next page or the previous page in response to a tilt of the mobile terminal in a specific direction while the touchscreen is in the touch lock mode.

5. The method of claim 1 , further comprising:
displaying event information on the touchscreen while the touchscreen is in the touch lock mode, the displayed event information overlapping the displayed first specific page, wherein the event information comprises at least message caption information, call reception information, or email reception information.

6. The method of claim 1 , further comprising continuing the displaying of the first specific page on the touchscreen in the touch lock mode in response to receiving a drag input in a second direction at the touchscreen that is in the touch lock mode.

7. The method of claim 1 , further comprising:
displaying a specific indicator corresponding to a second specific page of the e-book content while the touchscreen is in the touch lock mode;
causing the touchscreen to exit the touch lock mode in response to receiving the drag input selecting the specific indicator; and
displaying the second specific page after the exiting of the touch lock mode.

8. The method of claim 7 , wherein the second specific page corresponds to at least one of a particular page of the e-book content, the next page, or the previous page.

9. The method of claim 7 , wherein the second specific page corresponds to a bookmarked page of the e-book content.

10. The method of claim 6 , wherein the first direction is perpendicular to the second direction.

11. The method of claim 6 , further comprising displaying information other than the first specific page on the touchscreen that is displaying the first specific page in the touch lock mode.

12. The method of claim 11 , wherein the drag input in the second direction is received while the information and the first specific page are displayed on the touchscreen that is in the touch lock mode.

13. The method of claim 12 , further comprising causing the touchscreen to not display the information when the first specific page is continuously displayed on the touchscreen in the touch lock mode in response to the drag input in the second direction.

14. A mobile terminal comprising:
a touchscreen; and
a controller configured to:
cause the touchscreen to display a first specific page of e-book content comprising a plurality of pages while the touchscreen is in a touch unlock mode;

cause the touchscreen, on which the first specific page is displayed, to enter a touch lock mode;
cause the touchscreen that entered the touch lock mode to display the first specific page; and
cause the touchscreen to exit the touch lock mode and display a next or previous page of the e-book content in response to receiving a drag input in a first direction at the touchscreen that is in the touch lock mode.

15. The mobile terminal of claim 14 , wherein the controller is further configured to cause the touchscreen to continue the displaying of the first specific page on the touchscreen in the touch lock mode in response to receiving a drag input in a second direction at the touchscreen that is in the touch lock mode.

16. The mobile terminal of claim 14 , wherein the touchscreen enters the touch lock mode when not receiving an input of a touch action for a threshold time duration during the touch unlock mode or when receiving a user command to lock the touchscreen.

17. The mobile terminal of claim 14 , wherein the controller is further configured to:
cause the touchscreen to display a memo icon while the touchscreen is in the touch lock mode;
activate a memo application in response to receiving a touch input selecting the memo icon via the touchscreen;
receive a handwriting touch input via the touchscreen to the memo application for drawing a handwriting object; and
cause the touchscreen to display the handwriting object with a path of the handwriting touch input on the first specific page of the e-book content.

18. The mobile terminal of claim 14 , wherein the controller is further configured to:
cause the touchscreen to display the next or the previous page in response to tilting of the mobile terminal in a specific direction while the touchscreen is in the touch lock mode.

19. The mobile terminal of claim 14 , wherein the controller is further configured to:
cause the touchscreen to display a specific indicator corresponding to a second specific page of the e-book content while the touchscreen is in the touch lock mode;
cause the touchscreen to exit the touch lock mode in response to the drag input selecting the specific indicator; and
cause the touchscreen to display the second specific page after the exiting of the touch lock mode.

20. The mobile terminal of claim 19 , wherein the second specific page corresponds to at least one of a particular page of the e-book content, the next page, or the previous page.
