Abstract

A method of controlling a display device that displays an application execution window on a screen of the display device is provided. The method includes displaying at least one windows, each of the at least one window displaying an application, determining whether a lock command is input into a particular window of the at least one window, and if it is determined that the lock command is input, displaying only a window into which the lock command has been input in a locked state.

Claims

1. A method of controlling a display device that displays an application execution window on a screen of the display device, the method comprising:

displaying at least one window, each of the at least one window displaying an application;

determining whether a lock command is input into a particular window of the at least one window; and

if it is determined that the lock command has been input, displaying only a window into which the lock command has been input in a locked state.

2. The method of claim 1, wherein the displaying of the at least one window comprises:

displaying a title bar including a lock control button for inputting at least one of a lock command and an unlock command of the window; and

displaying an application execution screen.

3. The method of claim 2, wherein the determining of whether the lock command is input into the particular window of the at least one window comprises determining whether a lock control button, included in the particular window, is touched.

4. The method of claim 2, wherein the determining of whether the lock command is input into the particular window of the at least one window comprises determining whether a downward drag gesture, from a title bar included in the particular window, is input.

5. The method of claim 1, wherein the determining of whether the lock command is input into the particular window of the at least one window comprises determining whether a gesture of covering a camera module, included in the display device, is input.

6. The method of claim 1, wherein the determining of whether the lock command is input into the particular window of the at least one window comprises determining whether a gesture of covering a particular window is input.

7. The method of claim 6, wherein it is determined that the lock command has been input based on at least one of the gesture of covering the particular window photographed by the camera module included in the display device and a touch of the particular window corresponding to a preset percentage or more area.

8. The method of claim 1, wherein the displaying of only the window into which the lock command has been input in the locked state comprises:

replacing an application execution screen of the window into which the lock command has been input with a lock screen; and

displaying the replaced lock screen.

9. The method of claim 8, wherein the lock screen has at least one of a color and a brightness different from that of the application execution screen of the window into which the lock command has been input.

10. The method of claim 2, wherein the displaying of only the window into which the lock command has been input in the locked state comprises:

controlling to place a title bar, included in the window into which the lock command has been input, on a lower end of a touch screen of the display device; and

controlling not to display an application execution screen included in the window.

11. The method of claim 1, wherein the displaying of only the window into which the lock command has been input in the locked state comprises controlling not to display the window into which the lock command has been input.

12. The method of claim 1, further comprising determining whether an unlock command is input into the window into which the lock command has been input after the displaying of only the window into which the lock command has been input in the locked state.

13. The method of claim 12, wherein the displaying of the at least one window comprises displaying at least one of a title bar, including a lock control button used for inputting at least one of a lock command and an unlock command of the window, and an application execution screen, and

wherein the determining of whether the unlock command is input into the window into which the lock command has been input comprises determining whether the lock control button is touched.

14. The method of claim 12, wherein the determining of whether the unlock command is input into the window into which the lock command has been input comprises determining whether an upward drag, from a lower boundary of the window displayed in the locked state, is input.

15. The method of claim 12, wherein the lock command is a downward drag gesture input from a title bar included in the particular window,

wherein the displaying of only the window into which the lock command has been input in the locked state comprises:

moving the title bar to an end point of the downward drag gesture to display the title bar on the end point of the downward drag gesture; and

displaying remaining areas of the window into which the lock command has been input as a lock screen, and

wherein the determining of whether the unlock command is input into the window into which the lock command has been input comprises determining whether an upward drag, from the moved and displayed title bar, is input.

16. The method of claim 12, wherein the determining of whether the unlock command is input into the window into which the lock command has been input comprises determining whether a gesture of tilting or shaking the display device, in at least one of a left direction and a right direction, is input.

wherein the unlock command is an upward drag from the title bar placed on the lower end of the touch screen.

18. The method of claim 12, further comprising displaying a password input screen into which a password, for unlocking the window into which the lock command has been input, is inputted after the determining of whether the unlock command is input into the window into which the lock command has been input.

19. The method of claim 18, further comprising:

replacing a lock screen displayed in the locked state with an application execution screen; and

displaying the replaced application execution screen when the password input into the password input screen matches a preset password.

20. The method of claim 19, wherein the replacing of the lock screen displayed in the locked state with the application execution screen and the displaying of the replaced application execution screen comprise:
