Abstract

A mobile terminal and a displaying method thereof are provided. The mobile terminal includes a first touch screen which displays a first object, a second touch screen which displays a second object, and a controller which controls display of a virtual keypad on the second touch screen when a touch input is applied to the first touch screen.

Claims

1. A mobile terminal, comprising:

a first touch screen which displays a first object;

a second touch screen which displays a second object; and

a controller which controls display of a virtual keypad on the second touch screen when a touch input is applied to the first touch screen.

2. The mobile terminal of claim 1, wherein the controller controls display of the virtual keypad over at least a portion of the second object.

3. The mobile terminal of claim 1, wherein the first object includes at least one input window, and the touch input applied to the first touch screen is a touch applied to the at least one input window which waits for an input from a user.

4. The mobile terminal of claim 3, wherein the at least one input window is one that waits for an input corresponding to an ID of the user or a password corresponding to the ID, and the controller rearranges and displays a plurality of key buttons of the virtual keypad in a corresponding order of characters of the ID or the password.

5. The mobile terminal of claim 4, wherein, when the at least one input window is one that waits for the input corresponding to the ID of the user, the first object further includes another window that waits for an input of the password corresponding to the ID, and the controller controls appearance of a key button of the virtual keypad that enables input of the password into the another window.

6. The mobile terminal of claim 1, wherein the controller controls display of a first portion of the virtual keypad over a portion of the first object on the first touch screen and a second portion of the virtual keypad over a portion of the second object on the second touch screen.

7. The mobile terminal of claim 6, wherein the controller transmits an input value input through the virtual keypad to both the first and second objects when the first and second portions of the virtual keypad are displayed over respective portions of the first and second touch screens.

8. The mobile terminal of claim 6, wherein the first and second portions of the virtual keypad are displayed over the respective portions of the first and second touch screen by a touch-and-drag of the displayed virtual keypad from the second touch screen to the portion of the first touch screen.

9. The mobile terminal of claim 1, wherein the controller displays a cursor for indicating a standby state of waiting for an input from the user in an input window to which the touch input is applied.

10. The mobile terminal of claim 1, wherein the controller reduces an area in which the second object is displayed on the second touch screen by a region in which the virtual keypad is to be displayed and displays the virtual keypad in the region.

11. The mobile terminal of claim 1, wherein the first object includes a first window, the controller control display of words or texts that were input previously by the user on the first touch screen, and, when the user drags and drops one of the words or texts on the virtual keypad, the controller controls display of the dragged and dropped word or text in the first window.

12. The mobile terminal of claim 1, wherein the first object includes a first window, the controller control display of words or texts that were input previously by the user on the first touch screen, and, when the user drag and drops one of the words or texts on the first window, the controller controls display of the dragged and dropped word in the first window.

13. The mobile terminal of claim 1, wherein the virtual keypad is a QWERTY keyboard or a handwriting recognition input board.

14. The mobile terminal of claim 1, wherein the first and second touch screens are physically separated from each other.

15. A mobile terminal, comprising:

a plurality of touch screens including at least one input window; and

a controller which controls display of a virtual keypad on one of the plurality of touch screens, on which an input window for receiving a touch input is not displayed.

16. The mobile terminal of claim 15, wherein objects are respectively displayed on the plurality of touch screens, the controller reduces an area of an object that is displayed on the one of the plurality of touch screens displaying the virtual keypad by a region allocated for display of the virtual keypad and displays the virtual keypad in the region.

17. The mobile terminal of claim 15, where the input window is one that waits for an input corresponding to an ID of a user or a password corresponding to the ID, and the controller rearranges and displays a plurality of key buttons of the virtual keypad in a corresponding order of characters of the ID or the password.

18. A displaying method of a mobile terminal, the method comprising:

receiving a touch input applied to one of first and second touch screens; and

displaying a virtual keypad on the other of the first and second touch screens.

19. The displaying method of claim 18, wherein the displaying of the virtual keypad includes reducing an area in which an object is displayed on the other of the first and second touch screens by a region in which the virtual keypad is to be displayed, and displaying the virtual keypad in the region.

20. The displaying method of claim 18, further comprising transmitting an input value that is input through the displayed virtual keypad to an object displayed on the one of first and second touch screens receiving the touch input, and displaying the input value on the object.

21. The displaying method of claim 18, further comprising:

moving the displayed virtual keypad such that respective portions of the virtual keypad is displayed on both the first and second touch screens; and

transmitting an input value input through the virtual keypad to first and second objects respectively displayed on the first and second touch screens for simultaneous display of the input value on the first and second objects.

22. A mobile terminal, comprising:

a first touch screen, when activated by a touch input thereto, is enabled to receive input of characters; and

a second touch screen, when the first touch screen is activated by the touch input, is caused to display a virtual keypad usable to input the characters for the first touch screen.

23. The mobile terminal of claim 22, wherein the first touch screen and the second touch screen each display different portions of the virtual keypad.
