Abstract

A mobile terminal is disclosed. A mobile terminal according to one embodiment of the preset invention includes a first touch screen including a sub display, a second touch screen including a main display, a touch recognition sensor configured to recognize a first touch input and a second touch input starting on a first position of the first touch screen, a memory configured to store the recognized first touch input and the second touch input as a unlock pattern and if a third touch input and a fourth touch input starting on a second position of the first touch screen are recognized by the touch recognition sensor, a controller configured to compare the unlock pattern stored in the memory with the recognized third touch input and the fourth touch input and execute unlock of the main display according to a result of the comparison.

First claim

What is claimed is:

1. A method of controlling a mobile terminal, comprising:
recognizing a first touch input and a second touch input at a first touch screen, the first touch input to start at a first position on the first touch screen;
outputting, from the second touch screen, an indicator corresponding to the recognized first touch input and the second touch input, wherein the first touch screen has a different direction than the second touch screen, and the second touch screen corresponds to a main screen of the mobile terminal;
storing, in a memory, an unlock pattern based on the recognized first touch input and the second touch input;
recognizing a third touch input and a fourth touch input at the first touch screen, the third touch input to start at a second position on the first touch screen;
outputting, from the second touch screen, an indicator corresponding to the recognized third touch input and the fourth touch input;
comparing the stored unlock pattern with the recognized third touch input and the fourth touch input; and
executing an unlock of the main display based on a result of the comparing,
wherein in response to recognizing the third touch input at an end point of the first touch screen, the method further comprising adding distance information of a newly touched third touch input and distance information of a previously touched third touch input.

2. The method of claim 1 , wherein the recognized first touch input includes direction information and distance information of the first touch input, the recognized second touch input includes direction information and distance information of the second touch input, and wherein the direction information of the first touch input is opposite to the direction information of the second touch input.

3. The method of claim 1 , wherein the second position on the first touch screen is different than the first position on the first touch screen.

4. The method of claim 1 , wherein in response to recognizing the fourth touch input at the end point of the first touch screen, the method further comprising adding distance information of a newly touched fourth touch input and distance information of a previously touched fourth touch input.

5. The method of claim 1 , in response to display of an application at the first touch screen at a position adjacent to the second position on the first touch screen, the method further comprising:
generating a command for executing the application after the executing of the unlock of the main display; and
executing the application based on the generated command.

6. The method of claim 2 , further comprising:
outputting, on a first area of the first touch screen, a total number of units corresponding to the distance information of the first touch input;
outputting, on the first area of the first touch screen, a total number of units corresponding to the distance information of the second touch input on the first area of the first touch screen; and
outputting, on a second area of the second touch screen, a progressive bar based on the distance information and the direction information of the first touch input and the distance information and the direction information of the second touch input.

7. The method of claim 1 , wherein an angle between the first touch screen and the second touch screen is greater than 0 degree and less than 90 degrees.

8. A mobile terminal comprising:
a first touch screen corresponding to a sub display;
a second touch screen corresponding to a main display, wherein the first touch screen has a different direction than the second touch screen;
a touch recognition sensor configured to recognize a first touch input and a second touch input on the first touch screen, the first touch input to start at a first position on the first touch screen, and to recognize a third touch input and a fourth touch input on the first touch screen, the third touch input to start at a second position on the first touch screen;
a memory configured to store an unlock pattern based on the recognized first touch input and the second touch input; and
a controller configured to compare the stored unlock pattern with the recognized third touch input and the fourth touch input, and to execute an unlock of the main display based on a result of the comparison,
wherein when the touch recognition sensor recognizes the third touch input at an end point of the first touch screen. the controller is configured to add distance information of a newly touched third touch input and distance information of a previously touched third touch input.

9. The mobile terminal of claim 8 , wherein the recognized first touch input includes direction information and distance information of the first touch input, the recognized second touch input includes direction information and distance information of the second touch input, and wherein the direction information of the first touch input is opposite to the direction information of the second touch input.

10. The mobile terminal of claim 8 , wherein the second position on the first touch screen is different than the first position on the first touch screen.

11. The mobile terminal of claim 8 , wherein when the touch recognition sensor recognizes the fourth touch input at the end point of the first touch screen, the controller is configured to add distance information of a newly touched fourth touch input and distance information of a previously touched fourth touch input.

12. The mobile terminal of claim 8 , wherein when an application is displayed on the second touch screen adjacent to the second position on the first touch screen, the controller is configured to execute the application after the unlock of the main display is executed or at a same time as the unlock of the main display.

13. The mobile terminal of claim 8 , wherein the controller is configured to output, on a first area of the second touch screen, a total number of units corresponding to the distance information of the first touch input, to output, on the first area of the second touch screen, a total number of units corresponding to the distance information of the second touch input, and to output, on a second area of the second touch screen, a progressive bar based on the distance information and the direction information of the first touch input and the distance information and the direction information of the second touch input.

14. An apparatus comprising:
a first touch screen;
a second touch screen;
a touch recognition sensor to sense inputs at the first touch screen and the second touch screen; and
a controller to receive first information from the touch recognition sensor relating to a first touch and a subsequent second touch at the first touch screen, and the controller to store the first information in a memory as unlock information, the controller to receive second information from the touch recognition sensor relating to a third touch and a subsequent fourth touch at the first touch screen, and the controller to compare the stored first information with the second information, and to execute an unlock of the second touch screen based on a result of the comparison,
wherein in response to the third touch being at an end point of the first touch screen, the controller is to combine distance information of a newly touched third touch and distance information of a previously touched third touch.

15. The apparatus of claim 14 , wherein the first information includes direction information and distance information of the first touch and direction information and distance information of the second touch, and wherein a dir
