FIG. 3 is a conceptual diagram showing the mutual operation of the image display apparatus 200 and the external input apparatus 300 according to the present invention. Here, for the purpose of explanation, a TV is shown as an example of the video display device 200, and a space remote controller is shown as an example of the external input device 300

Referring to FIG. 3, the external input device 300 can transmit and receive signals to and from the image display device 200 according to the RF communication standard. A control menu may be displayed on the screen of the video display device 200 according to a control signal of the external input device 300. To this end, the external input device 300 may include a plurality of buttons, and may generate an external input signal according to a user's operation of the button. In addition, the external input device 300 can transmit the information about the motion of the external input device 300 sensed through the sensing unit in the 3D space to the image display device 200. [

3, in response to the user moving or rotating the external input apparatus 300 up / down, left / right, front / back, or the like, the screen of the image display apparatus 200 displays, on the movement of the external input apparatus 300, A corresponding pointer is displayed. The external input device 300 can be referred to as a spatial remote controller because the pointer moves according to the motion in the 3D space and is displayed on the screen of the image display device 200. [

The information on the motion of the external input device 300 sensed through the sensing unit of the external input device 300 is transmitted to the image display device 200. Then, the image display apparatus 200 can calculate the X and Y coordinates of the pointer from information on the motion of the external input apparatus 300. [ The image display device 200 can display a pointer corresponding to the calculated coordinates.

If the user moves the external input device 300 away from the screen of the video display device 200 while the specific button provided in the external input device 300 is pressed, The selection area can be zoomed in (zoomed out) and zoomed in (zoomed out). On the other hand, when the user moves the external input device 300 so as to approach the screen of the video display device 200, the selected area in the screen corresponding to the pointer displayed on the screen is zoomed out (zoomed in) .

On the other hand, when the specific button provided on the external input device 300 is pressed, the recognition of the upward / downward and leftward / rightward movement of the external input device 300 can be excluded. That is, when the external input device 300 moves away from or approaches the screen of the image display device 200, only the forward / backward movement can be recognized without recognizing the upward, downward, leftward, and rightward movement.

In addition, the moving speed of the pointer displayed on the screen of the image display device 200, the moving direction, and the screen scroll speed according to the movement can be determined according to the moving speed and / or the moving direction of the external input device 300. [ Here, the pointer may be formed in various shapes other than an arrow shape, for example, a point, a cursor, a prompt, and an outline.

The controller 270 displays at least one object whose function is activated by the pointing signal in one area of the display unit 280 of the image display apparatus 200. The controller 270 controls the interface unit 250, For example, a spatial remote controller, via the external input device 300, for example. If the pointer displayed on the display unit 280 moves in the first area where the object is not displayed according to the received pointing signal, the controller 270 controls the pointer to move to the first moving speed. If the pointer displayed on the display unit 280 moves in the second area in which the object is displayed according to the received pointing signal, the controller 270 controls the second moving speed to be slower than the first moving speed.

In this case, when an object (e.g., a key) displayed on the image display device 200 is selected using the pointing signal transmitted from the external input device 300, if the pointer enters the area where the object is displayed, So that the user can easily control the object (for example, object selection).

Hereinafter, when a screen of the mobile terminal (for example, a screen corresponding to the portrait mode of the mobile terminal) is displayed on a video display device (for example, a video display device having a 21 to 9 ratio screen) An image display apparatus and its control method capable of utilizing the unused display area by displaying information in an unused display area of the image display apparatus 200 will be described. For example, when a screen of the mobile terminal (e.g., a screen corresponding to the portrait mode of the mobile terminal) is displayed on a video display device (for example, a video having a screen of 21 to 9 ratio) through mirroring or mirroring (For example, a screen corresponding to the portrait mode of the mobile terminal) is displayed only in a partial display area of the image display device 200 when the image display device 200 is displayed on the display device 200, And the other part exists as an unused display area. On the other hand, when a screen corresponding to the landscape mode of the mobile terminal is displayed on an image display device (for example, a video display device having a screen of 21 to 9 ratio) 200, Can be displayed in the entire display area of the display device (for example, a video display device having a 21 to 9 ratio screen) (200).

For example, a screen of a video display device (for example, a video display device having a screen of 21 to 9 ratio) 200 is displayed on a screen corresponding to the portrait mode of the mobile terminal through mirroring or mirroring (For example, a video display device having a screen of 21 to 9 ratio) 200 is displayed only in a part of the display area of the mobile terminal, so that another part of the mobile terminal exists as an unused display area . On the other hand, when a screen of a video display device (for example, a video display device having a 21 to 9 ratio screen) is displayed on a screen corresponding to the landscape mode of the mobile terminal, The screen of the video display device 200 having a screen of a ratio of 9 may be displayed in the entire display area of the screen corresponding to the landscape mode of the mobile terminal.
