4 is a flowchart illustrating a display sharing method of a mobile terminal according to an embodiment of the present invention.

First, the controller 180 of the mobile terminal 100 sets up display sharing with at least one or more other terminals according to a user input received from the user input unit 130 (S101). In this case, the controller 180 of the mobile terminal 100 may search for other terminals located close to the terminal by using near field communication, and may selectively set display sharing among the searched other terminals.

In addition, one terminal among the terminals connected to each other through the display sharing setting is set as the main terminal, and the other terminals are set as the sub terminals. In this embodiment, the mobile terminal 100 is set as a main terminal and the other terminals are set as sub terminals.

In addition, other terminals, which are sub-terminals, automatically transmit phone numbers (or identification information, terminal names, etc.) of other terminals to the mobile terminal 100 according to the connection setting information.

After the display sharing setting is completed between the terminals, the controller 180 of the mobile terminal 100 detects occurrence of a specific event while performing a predetermined task (S102). For example, as shown in FIG. 5A, when the mobile terminal 100 receives a call signal through the wireless communication unit 110 while the mobile terminal 100 plays a video file and displays the video file on the display screen, The controller 180 detects reception of the call signal.

The controller 180 checks whether the specific event occurred is a network-related event (S103).

As a result of the check, if the specific event occurred is a network-related event, the controller 180 transmits the generated specific event to another terminal for setting the display sharing (S104). For example, the controller 180 of the mobile terminal 100 forwards a call signal received during video playback to the other terminal. That is, the mobile terminal 100 transfers the incoming call to the other terminal through the display sharing setting. Accordingly, the controller 180 of the mobile terminal 100 displays the played video on the display screen without interrupting the video playback, and the controller of the other terminal 200 displays the call as shown in FIG. 5 (b). Output the reception screen to the display.

If the specific event occurs as a non-network related event, the controller 180 transmits the generated specific event to another terminal in the background using short-range communication (S105). Meanwhile, the controller 180 of the mobile terminal 100 executes a specific event that has occurred, and transmits screen information displayed on the display screen to another terminal (sub terminal) connected to the mobile terminal 100.

6 is a flowchart illustrating a display sharing method by a mobile terminal according to another embodiment of the present invention.

When the display sharing request is requested from the user or the other terminal 200 during the multitasking, the controller 180 of the mobile terminal 100 connects the display sharing with the other terminal 200 based on the display sharing setting information. (S201, S202).

When the display sharing setting is completed, the controller 180 of the mobile terminal 100 displays a list of currently running applications (job list) on the display screen (S203). In this case, the controller 180 displays execution screens (work screens) of the application in thumbnail form.

The controller 180 selects at least one or more applications from a list of applications displayed on the display screen according to a user input in operation S204. For example, as shown in FIG. 7A, any one application selected from the list of applications displayed on the display screen of the mobile terminal 100 is selected and thrown to another terminal 200 connected to the mobile terminal 100. Perform the same action.

The controller 180 of the mobile terminal 100 transmits data related to the selected application to the other terminal 200 so that the selected application can be executed in another terminal 200 connected to the mobile terminal 100 ( S205). In this case, the same application as the selected application should exist in the other terminal 200, and the controller 180 transmits data or events related to the selected application to the other terminal 200 through short-range wireless communication. The controller of the other terminal 200 processes the received data or event through the application. For example, the user may select an application 'App # 4' from the list of applications displayed on the display screen of the first mobile terminal, and perform an action such as flicking in the direction in which the second mobile terminal 200 is located. In operation, the first mobile terminal 100 transmits data related to the selected application to the second mobile terminal 200. The second mobile terminal 200 moves the first mobile terminal as shown in FIG. Receives data transmitted from the terminal 100 and executes the selected application. In other words, when the selected application is a video player, the first mobile terminal 100 transmits the video file being played to the second mobile terminal 200. The second mobile terminal 200 executes a video player to play and display the received video file.

On the other hand, if the application is to be downloaded from the web, the other terminal 200 generates a popup to inquire whether or not to receive the application so that the user can select it. In this case, when the reception of the application is permitted, the other terminal 200 downloads the application from the web and executes it.

While the first mobile terminal 100 is writing a message through the message application, the controller 180 of the first mobile terminal 100 shares the display with the second mobile terminal 200 based on preset connection setting information. To establish a connection.

When the connection setting is completed, the controller 180 of the first mobile terminal 100 classifies at least one or more items displayed on the display screen by the number of terminals connected to each other for display sharing. For example, as shown in FIG. 8, in a state in which a message writing screen and a keypad icon for message input are displayed on the display unit 151 of the first mobile terminal 100, the first mobile terminal 100 and the second mobile terminal are moved. When the terminal 200 completes the connection setting for the display sharing, the first mobile terminal 100 requests display of a keypad icon on the second mobile terminal 200. That is, only the message preparation screen is displayed on the display screen of the first mobile terminal 100, and a keypad icon is displayed on the display screen of the second mobile terminal 200.

Subsequently, when data is input through a keypad icon displayed on the touch screen of the second mobile terminal 200, the control unit of the second mobile terminal transmits data input through Wi-Fi and Bluetooth to the first mobile terminal 100. do. The controller 180 of the first mobile terminal 100 receives input data transmitted from the second mobile terminal 200 through the short range communication module 114 and inserts the input data into the message input field of the message creation screen.

In the above-described embodiment, a case of writing a text message has been described as an example, but may be applied to other application execution. For example, when executing video editing, the controller 180 of the mobile terminal 100 displays a screen for editing on the display screen, and edited on the display screen of another terminal 200 connected to the mobile terminal 100. Display the screen or display the editing tool.

9 illustrates an example in which a mobile terminal according to an embodiment of the present invention sets a display.

The controller 180 of the mobile terminal 100 performs connection setup for display sharing with at least one terminal. Thereafter, when the display setting is requested by the user, the controller 180 enters the display screen setting mode.

Upon entering the display screen setting mode, the controller 180 configures and displays the entire display screen in a plurality of areas (represented in a square shape), and displays a list of terminals (devices) connected to the terminal.

If a predetermined area constituting the entire screen is selected according to a user's touch and drag input, the controller 180 sets the size of the multi-screen as the size of the selected area (a).

In addition, when the multi-screen size setting is completed, the controller 180 allocates a terminal in the list of connected devices for each of the selected regions (b).

The controller 180 may also set an aspect ratio according to a user input. For example, if data is displayed separately on the TV and the phone screen, since the screen is larger on the TV, the data is divided into 8: 2 so that 8/10 of the data is displayed on the TV screen. It is displayed on the phone screen (c). In other words, when a device is set in the selected predetermined area, the controller 180 obtains display screen size information of the set device and determines a data ratio to be displayed among all data based on the screen size information.

In addition, when the full screen is displayed on a plurality of connected device screens, the controller 180 may change or rotate the screens for each device (d).

10 illustrates an example in which a mobile terminal according to an embodiment of the present invention stores data during display sharing.

The mobile terminal 100 divides the display screen according to the multi-screen setting and displays different data in the divided area. For example, as shown in the drawing, the controller 180 displays a preview screen of an image file transmitted from the first sub terminal and a video file transmitted from the second sub terminal. When the image file or the video file is dragged to the storage icon, the controller 180 detects the drag input and stores the image file or the video file in the memory 160 of the mobile terminal 100 (a).

In addition, if the storage icon is selected while the mobile terminal 100 plays and displays an image or video file transmitted from another terminal, the controller 180 controls the memory 160 of the mobile terminal 100 to display the displayed file. (B).
