Abstract

A mobile terminal and a method of executing a call function using the mobile terminal are provided such that the call function is executed in the mobile terminal including a plurality of touch screens, and various graphic user interfaces with respect to the call function are displayed to a user such that the user can conveniently use the call function.

Claims

1. A method of operating a mobile terminal having a first touch panel and a second touch panel, the first and second panels being movable relative to each other, the method comprising:

displaying content on at least one of the first touch panel or the second touch panel in a state other than a closed state of the first and second touch panels, wherein in a closed state, the first touch panel is parallel to the second touch panel and the first touch panel and the second touch panel face in opposite directions;

receiving a call when the content is displayed on at least one of the first touch panel or the second touch panel;

determining whether the call is accepted based on one of a user selection on the first touch panel or change of the state to the closed state; and

locking the first and second touch panel when the call is accepted.

3. The mobile terminal of claim 1, wherein the first and second panels are connected to each other by at least one hinge such that the first and second panels are foldable relative to each other.

4. The mobile terminal of claim 1, wherein the call is placed in speaker phone mode when the state of the first and second touch panels changes to an open status while the call is connected.

5. The mobile terminal of claim 4, wherein the first and second touch panels are arranged in a substantially same plane in a fully open status.

6. The mobile terminal of claim 4, wherein the speaker phone mode is cancelled when the state of the first and second touch panels changes to closed status while the call is connected in the speaker phone mode.

7. The mobile terminal of claim 1, wherein the display of content is halted when the call is received or the received call is connected.

8. The mobile terminal of claim 7, wherein the display of the content is continued when the connected call is ended.

9. The mobile terminal of claim 7, wherein the display of content is continued when the state of the first and second touch panels changes to an open status while the call is connected.

2. A method of operating a mobile terminal having a first touch panel and a second touch panel, the first and second panels being movable relative to each other, the method comprising:

providing content on at least one of the first touch panel or the second touch panel in an open state, wherein in the open state, a prescribed angle exist between the first touch panel and the second touch panel such that the first touch panel and the second touch panel face substantially in the same direction;

receiving a call when the content is displayed on at least one of the first touch panel or the second touch panel;

determining the call is accepted based on one of an initial change of the prescribed angle between the first touch panel and the second touch panel or substantially simultaneous input to the first touch panel and the second touch panel; and

locking the first and second touch panel when the call is accepted.

10. The method of claim 11, wherein the first touch panel and the second touch panel are coupled by a hinge such that the mobile terminal can be folded, a side of the mobile terminal to which the first touch panel is attached and a side of the mobile terminal to which the second touch panel is attached do not come into contact with each other in the closed status, and the first touch panel and the second touch panel are arranged in a substantially same plane in a fully open status.

11. The method of claim 2, wherein the substantially simultaneous input to the first touch panel and the second touch panel is provided by touching the first touch panel with one hand and touching the second touch panel by the other hand.

12. A display device comprising:

a first touch panel;

a second touch panel, the first and second panels being movable relative to each other; and

a controller to control the first and second touch panels,

content is provided on at least one of the first touch panel or the second touch panel in a state other than a closed state of the first and second touch panels,

in a closed state, the first touch panel is parallel to the second touch panel and the first touch panel and the second touch panel face in opposite directions, and

the first and second touch panels are locked when an incoming call is accepted based on one of user selection on the first touch panel or change of the state to the closed state.

13. A display device comprising:

a first touch panel;

a second touch panel, the first and second panels being movable relative to each other; and

a controller to control the first and second touch panels,

content is provided on at least one of the first touch panel or the second touch panel in an open state,

in the open state, a prescribed angle exist between the first touch panel and the second touch panel such that the first touch panel and the second touch panel face substantially in the same direction, and

the first and second touch panels are locked when an incoming call is accepted based on one of an initial change of the prescribed angle between the first touch panel and the second touch panel or substantially simultaneous input to the first touch panel and the second touch panel.
