For example, when receiving an input for the end button 11 during a call, the controller 180 removes the call execution screen 10 and the item list 20 from the touch screen 151, before executing the call. The screen may be displayed on the touch screen 151 again. For example, when receiving an input for the message button 12 during a call, the controller 180 terminates the call after performing a process of delivering a predefined message to the call counterpart, and displays the call execution screen. May be displayed on the touch screen 151.

The item list 20 may include at least one item. The item list 20 may be a set of candidate items to be displayed on the touch screen 151 after the call ends.

The at least one item may include an execution screen, an application icon, a multimedia content icon, a multimedia content play screen, and the like of a specific item. For example, the at least one item may include an execution screen 21 of a messenger application and a standby screen 22 for displaying at least one application.

The controller 180 may display the item list 20 together with the call execution screen 10 on the touch screen 151 while the call execution screen 10 is displayed on the touch screen 151 during a call. . In addition, when a touch input for selecting one of at least one item 21 or 22 included in the item list 20 is received, the controller 180 determines that the selected item is terminated when the running call ends. The screen associated with the screen may be automatically displayed on the touch screen 151.

Therefore, when a call is connected while executing the first item through the touch screen 151, the call call connection may be an interrupt signal for stopping execution of the first item. You must go through the procedure for the execution of the first item.

According to an embodiment of the present invention, the call execution screen 10 is displayed on the touch screen 151, by providing a list of items to be provided on the touch screen 151 after the call is terminated, whereby the user is included in the list. It is possible to select one of the items, and to continue the execution of the item after the call ends.

5 is an example of an item list according to an embodiment of the present invention.

Referring to FIG. 5, the item list 20 may include an execution screen of a specific application or a capture screen 21 of an execution screen of the specific application. In addition, the item list 20 may include a standby screen (or home screen) 22 in which at least one item is arranged. In addition, the item list 20 may include a video playback screen 23.

The item list 20 may include a live image of the item as well as a captured image of the item execution screen.

Meanwhile, the controller 180 may search for a plurality of items as a flicking input is received for at least one item included in the item list 20.

The controller 180 may automatically display a screen related to the selected item on the touch screen 151 after a call is ended after the searched specific item is selected.

6 is an example of a screen displayed on the touch screen 151 after ending a call according to an embodiment of the present invention.

When the controller 180 receives an input for selecting the execution screen of the messenger application from the item list, the controller 180 may display the call execution screen after the call is completed by replacing the messenger application execution screen IE.

7 illustrates an example of moving a list of items displayed together with a call execution screen according to an embodiment of the present invention.

The controller 180 may display the item list 20 on one area of the call execution screen 10. When the controller 180 receives a predetermined touch input (for example, a long touch input) with respect to the item list 20, the controller 180 may change the position of the item list 20. In this case, when the call execution screen 10 and the overlapping region exist, the controller 180 may adjust the transparency of the item list 20.

8 is a diagram illustrating an example of adding a new item to an item list according to an embodiment of the present invention.

Referring to FIG. 8, the controller 180 may add a screen currently displayed on the touch screen 151 to the item list 20.

For example, when the controller 180 receives a predetermined touch input (long touch input) with respect to the standby screen 30 on which at least one icon is arranged, the controller 180 displays the standby screen 30 in the item list 20. Can be added to

When the controller 180 receives a long touch input with respect to the current idle screen 30 displayed on the touch screen 151, the controller 180 may provide a message pop-up window 40 for adding an application to the touch screen 151. Can be.

On the other hand, after the current standby screen 30 is added to the item list 20, when receiving a call call connection signal from an external device, the controller 180 displays the call execution screen 10 and the item list 20. It may be displayed on the touch screen 151.

Accordingly, when receiving a touch input for selecting specific items 21 and 25 included in the item list 20 during a call, the controller 180 may end the call with the selected item and then touch the screen 151. You can control it to display.

9 is a flowchart of a control method of a mobile terminal according to a second embodiment of the present invention, and FIG. 10 is a view for explaining a control method of a mobile terminal according to a second embodiment of the present invention.

9 to 10, the controller 180 may execute a specific item (S210). In addition, the controller 180 may receive an interrupt signal for stopping execution of the specific item (S220).

For example, the controller 180 may receive a call call connection signal from an external device while playing the multimedia content. Here, the call call connection signal is an interrupt signal for stopping the reproduction of the multimedia content 51.

When the call call connection signal is received (or when a call is connected), the controller 180 adds a screen 23 corresponding to the multimedia content 51 to the item list 20, and the item list. 20 may be displayed on the touch screen 151 together with the call execution screen 20.

Then, when the call ends, the controller 180 may release the mobile terminal 100 from the call mode and automatically enter the play mode of the multimedia content 51. Accordingly, continuity of multimedia content reproduction can be ensured.

The above-described method of controlling an electronic device according to the present invention can be provided by being recorded on a computer-readable recording medium as a program for execution on a computer.
